How far do the values of Kino Essay Example for Free

How far do the values of kino EssayA. The Novelette, The drop cloth was written by John Steinbeck in 1944. Steinbeck is a magnificent author who uses dramatic, narrative and musical themes only told to bulge outher . e. g. the song of diabolical and the song of family to convey his idea effectively. He is able to attain an effect on the reader without lengthy details on emotions, places etc. All his novels are set in Salinas Valley and the main(prenominal) themes of his novels are on man versus nature and how man abuses it. Drama, visual effects and music all blend together in Steinbecks novel making it an all time classic.The Pearl is the story about gum kino (Main character Mexican fall diver) who is the leader of his race. In the story he goes on to finding a pearl, which affects him greatly. The pearl of the world gives him dreams of wealth and prosperity but all this changes when things dont turn out the way he planned them to. The pearl gives him suffering and bri ngs out the annoyance in man. At the beginning of the novel we follow out the Mexicans oneness with nature as they do songs about it which brought them happiness. The fishercommon people lives were very simple as they lived in destitution and yet they enjoyed the fruits of nature.They lived in brush houses and ate simple food like hot corn-cake. Their sense of unity in the family is shown as they hardly communicate through and through words because they know what and how one another thinks. (Page 10)- They had spoken once, but there is not need for speech if it is only a habit anyway. Songs were important in their culture as they linked everything to music. The tribe was so closely united and were always ready to help each other. We agree this when all the neighbors assist kino when he takes Coyotito to the doctor for the scorpion bite as a child was a most important thing in life.Another example of concentration is when the tribe goes with kino to sell the pearl as it a his toric event as one of their members are going to get a lot of money. This all shows the homage of the neighbors. The tribe is superstitious and at the same time religious, as it is shown to us when Juana prays and chants magic at the same time when seeing the scorpion. They had experience in treating the dangers of nature . e. g. scorpion bites. Both Kino and Juana are superstitious and this is evident when they find the pearl of the world, they hid excite workforcet and the pageant Gods were angry at them.The only thing that made the tribe unhappy was the whites treatment towards them which they thought was unjust. The whites brought fear and distrust . e. g. the way the doctor looks after and treats the rich rather than the poor. The poor lived in brush houses charm the rich lived in stone and plaster houses. The whites poison the minds of the tribe as they are victims of ignorance and illiteracy. They were made to believe that their remedies were inferior to those of the white when in most cases they were not.The tainted values of the whites are seen when the doctor misuses his skills and knowledge to make the baby sick instead of curing him. There is also ill-treatment of the beggars we see this when they dont help Kino in finding a doctor and they feel it is a source of entertainment when a fisherman comes for help in the city. Eg(When Kino wants to find a doctor for his son as he got bitten by a scorpion, and instead of the beggars helping Kino finding one, they made fun of him) The irony is that the beggars have no dignity compared to the fishermen who work for a living.When the tribe found the pearl they never thought of riches, only things that will help them where as compared to the whites they only thought of riches and themselves e. g. the doctor was fond of rich silk and expensive clothes compared to the fisher folks who just wore rags. Here a sense of irony is shown as the fisher folks are the whites main source of income and despite this, th ey still feel disgusted by the fisher folks. The priest was also a disgrace to religion as he too only thought about himself and riches as they wanted materialistic things.We also see how the whites treat their culture as to be very inferior and at the same time exploit them because the tribe is illiterate. Kino represents all the men in the tribe, he was the head of the family and showed the superiority of men e. g. when he eats first in his family and makes decisions. He is a protective father. This is evident when we see him confront the three trackers and when he tries to save his son from the scorpion bite. We see how the pearl changes him from a dependable, hard working man to a man who wants power.The main thing of a man is to have a canoe, as it was a sign of life. The tribe was of fishermen and they depend on canoe to fish in. Here we see Kinos loyalty to the family and family possessions as we see how he valued his canoe which he got from his grandfather-(Kinos grandfather had brought it from Nayarit, and he had given it to Kinos father, and so it had come to Kino) This is how the canoe is passed down from genesis to generation.. A canoe was passed down from ancestors and without one they wouldnt be able to get married as it would be hard to support a family.The canoe was a symbol of livelihood, prosperity, independence and survival. Many things were passed down from generations such as Pearl diving, fishing and use of seaweed for remedies. Kinos life is focused on his family whom he loved a lot. His love for Juana is shown when he wants the pearl to help them in getting married. The closeness and the sense of brotherly unity between Kino and his brother Tomas, they gain from the values of their forefathers, as we see how Tomas advises him about the pearl and also helps Kino when the pearl brings bad luck to him.Kino shows his care for the races when he wants the pearl to bring prosperity to the tribe rather than to himself alone we see how he wants education for his son as with education they wouldnt be victims to the whites, he wants his son to spread knowledge and understanding to his tribe in the future through the things he learned. Kino is a skilled fighter where his response to danger is fierce and quick. It is a primitive replete(predicate) of the tribe. He is known as a noble savage he is uncorrupted by a false coating of civilization that we see through the behavior and character of the doctor, priest and the pearl trader.The primitive violent reaction is shown when he attacks the thief that comes and robs him and when he murders one of the attackers in self-defense. When Kino finds a big hole in his canoe there is anger and deep herb of grace as without a canoe a man is helpless. He is like a machine when he flees from the attacker to high ground like an instinct of an animal. There is stubborn courage in Kino he displays a tragic courage for he is a man opposing all the forces against him. We see Kino is a man c onstant struggle against any prison that binds him.We see at the end of the story Kinos emotion when he loses his son and everything he owns because of the evil pearl and so a result he throws the pearl where it belongs. The situation of Kino could have happened to anyone in the tribe as all he imagined was that everyone would share his joy, but he was wrong. Juana represents all the females in the tribe as a womans character was obedient and respected. Her femininity was shown when she waits for Kino to finish eating and accordingly she would start eating. She respected her husband by making him choose decisions.Juana is an ideal partner for Kino like her instincts when she wants to throw the pearl, and by showing unquestionable loyalty by wanting to stay with Kino and refuses to leave him even though it meant life or death for her and her baby. She shows strength when Kino is weakened by the evil of the pearl. Because of this action Kino draws strength to her loyalty. When Kino s aid to Juana I am a man he meant that he was half insane and half idol and she knew in her womans soul that the forces of nature and society would crush him in the end, yet she needed such a man.Sometimes the female makes decisions for the men as a desperate measure like when she tells Kino to throw away the pearl. Both Kino and Juana were superstitious when finding the pearl and hence both of them suffered from the evil it brought as their simplicity and gullibility made them unaware about the pearls poison and the pain it brought as they suffered a terrible loss and were neglected by society. The dream Kino conjured from its shiny surface was to bring sorrow and death, as too much good luck gave them something bad at the end. But at last he had learnt his lesson and throws the pearl back into the sea where it belongs.There is always a limit to which you can make use of something. Once you begin to abuse it you pay the consequences and this is what happened. ending is a very impo rtant aspect of life as not only is it a symbol/identity but it is also something which no automobile trunk can take away from you as it becomes part of you. Every culture has its own occasions, celebrations, beliefs, dress etc. In The Pearl John Steinbeck used Kino and Juana very specifically to portray the importance of culture and the way things go about in a particular culture. Eg the way the canoe was passed down from generation to generation etc.

Why We Shouldnt Illegalize Guns Essay Example for Free

Why We Shouldnt Illegalize Guns EssayThe Sandy Hook shooting. The theater shooting. What do they have in public? Guns. The question though, is how we should limit them. Many think that we should completely illegalize them, but is it really going to solve the problem? The truth of the matter is that zeps dont turn thumbs down people the criminal that wields the gun kills people. Limiting the use of guns is non an ideal solution and it will not stop criminals from killing others.Its apprehensible that many people want to completely restrict guns be guinea pig of their personal experiences or tragedies of someone they know dealing with shootings or guns. Its also understandable that gun laws atomic number 18 passed only to look out for the safety of others. Guns stub be really dangerous once its placed in the wrong hands. expression from complete honesty, we can all agree that guns actually do help criminals kill or injure the innocent. Using a gun, a thief can easily rob a bank, or even a psychopath can easily gun down a school with just a press of a trigger. I mean, guns are dangerous right?Yes and no. Yes, because they can be a tool for evil and destruction. No, because they dont cause people to kill others, they serve only as a catalyst for the inevitable. If someone is insane enough to pick up a gun and kill innocent civilians, the problem doesnt lie inwardly the gun, but the beholder of the gun. This means that the thought of killing someone else will eventually manifest whether guns are present or not. Taking away guns isnt going to make criminals mentally sane or even less dangerous. The problem shouldnt be emphasized on the tool the perpetrator used, but on the perpetrator himself. Saying that it was a gun that caused a person to kill is like axiom if someone had a knife, he would automatically go out and slaughter innocent bystanders. Intentions are intentions. If someone really wanted to kill another person, they would, with or without a gun.But ok. Say a law was passed to illegalize all guns. Would it finally be a stop to all the madness and violent killings in America? Of course not. Illegalizing guns will only take away firearms from the law abiding citizens. Criminals that are likely to commit crimes are the ones that wont can to laws. And even if its against the law, whose stopping the criminals from obtaining arms illegally? This means that the law abiding citizens will have no guns to protect themselves, and the people that dont follow laws will have guns regardless.Even though a series of new-fashioned tragic events occurred, it shouldnt mean that owning guns should be made illegal. Illegalizing firearms will not cause anything but even more chaos. In fact, Crime rates in Great Britain have doubled since handguns were banned along with heavy parapet on long guns. Clearly, illegalizing guns will not decrease crime rates, but instead, increase them.Illegalizing guns. It does not seem to be a relevant respon se to recent shootings. Even if looking out for the safety of fellow citizens of America is the main goal, making guns illegal will not solve anything. The issue of the matter lies within the intentions of the gun wielder. Though guns may be a destructive tool, it is still the persons responsibility to adequately own and operate the gun bit obeying the laws. Guns themselves might seem like the easiest thing to blame for unforgivable crimes but, in truth, America should first focus on the people and the logical part of the situation.

Big Skinny Online Marketing Development

great(p) tight fitting Online Marketing Development tolerant thin consequence AnalysisExecutive SummaryIn 2010, prodigious tight CEO Kiril Alexandrov was looking to transcend from retail distribution and print advertising to the world of online selling to achieve maximum growth. The retail sales pitch was an easy one, as Alexandrov focused on the de marchesine of the purse and the impulsiveness of consumers (Benjamin Kominers, 2012). Unfortunately, translating this type of sales pitch was some(prenominal) harder to do in the world of cyberspace. swelled Skinny centered their online commercialiseing efforts around exhibit Ads, keyword searches, social media and relationships with online distributors and deep DISCOUNTED ranks such as Amazon and Groupon respectively. The intricacy caused much hardship, as super Skinny received negative feedback on the review website Yelp that stemmed from their Groupon experiment. They also faced a glitch in their online promotion that al lowed 4,000 people to order free wallets from their online store.Big Skinny needs to refocus their online marketing st enjoingy by getting rid of display Ads, down keyword searches and severing ties with deep DISCOUNTED sites. Big Skinny foundation make believe value for their crossing and manage their orders better by being more selective with who distributes their harvest-festival and by keeping the price steady. A more durational approach surrounding keyword searches can create new tax revenue from those who ar looking to propose quick and impulsive procures. Lastly, by being responsible for who distributes their overlaps, Big Skinny can deliver their product in prompt and timely manner, which give get back the majority of customer complaints against Big Skinny.Problem StatementDespite successful in- someone sales campaigns, Big Skinny struggled to find an effective online marketing curriculum that would grow and connect them to their consumer base. Big Skinny also ran into glitches with their current online marketing campaigns that brought unwanted negative attention and resentment towards the company.Data AnalysisWhen Big Skinny transcended into the world of online marketing, it had to develop a way to attract visitors to the website while attempting to convince these visitors to vitiate wallets. Since most of their wallets were being sold at trade shows or retail stores that centered on a straight-forward approach regarding impulse and value, the translation of this system to the internet proved to be a tall task.Big Skinny looked at various means of advertising such as display ads, algorithmic search, sponsored search, A/B Testing and social media. Display ads offered a two-frame animation unless, the click- through with(predicate) rate of general display ads in 2009 was only .1% (Bejamin Kominers, 2012). Algorithmic searches use algorithms that the search engine deems most relevant to the users interview. The websites that most rese mble the query appear the highest on the search engines list. Sponsored searches use keywords that the advertisers specify that they want to target. These are mostly sold on a per-click basis however the company loses money if the clicks arent converted into sales. A/B testing is a marketing technique that shows different advertisements to different users to compare the response grade between the two. Lastly, social media utilizes websites such as Facebook and Twitter to try and create an interactive relationship with consumers.AlternativesBig Skinny could eliminate their means of online distribution and compensable ONLINEmarketing, only utilizing social media and their website to conduct advertising and handicraft transactions.Big Skinny could be more selective in their selection of online distribution, while tailoring their salaried sponsored searches to generate interest and sales.Big Skinny could scrap their online marketing plans, with the exception of social media, and rea llot their advertising money strictly on deep DISCOUNTED sites corresponding Groupon and Living well-disposed.Big Skinny could focus their efforts on expanding in more brick and mortar retail stores by target marketing towards different demographics. They could use traditionalistic media such as TV and communicate to drive these efforts.Key Decision CriteriaIncrease customer satisfaction and corporate imageIncrease sales and market shareImprove (or at least maintain) profitabilityEase or speed of implantationBe consistent with corporate mission or strategyWithin our present resources or capabilitiesWithin acceptable risk parametersMinimize environmental impactMaintain and build employee morale and prideAlternatives Analysis1. By limiting their online marketing to free social media sites such as Twitter or Facebook, Big Skinny can greatly reduce their marketing embodys. With display advertisements only getting clicked through .1% of the time the money is essentially thrown away. Investing in A/B testing requires the hiring of a permanent person and huge overhead. Getting rid of online distributors allows Big Skinny to eliminate the 7-15% commission they put up to Amazon and eBay while being able to manage their order load. Social Media is more than enough because 71% of social media participants formulate they are more likely to purchase from a brand they follow online. 91% of local searchers say they use Facebook to find local businesses online (Bennett, 2013). The cons of this are that they are missing out on a lot of authorization customers by eliminating Amazon and eBay. While ONLINE paying marketing can be expensive, there is still benefit to sponsored searches. Some of the cost per conversions are profitable and by completely eliminating these searches would be throwing away potential opportunities.2. The pros of Big Skinny being more selective with their online distributors allows for a happy customer base. There have been several negative review s on the Yelp site regarding slow delivery and non-existent customer service. By eliminating deep discounting sites such as Groupon, Big Skinny can manage their order load and keep customers happy. Big Skinny would also keep the revenue from the top paid sponsored searches rather than eliminating them all together. The negatives of this are that Big Skinny could miss out on a lot of revenue by not using Groupon or Living Social. They could also miss out on the paraphrase customers that are generated by these sites as well as missing out on the people who want to try their product without having to pay full price.3. Instead of eliminating sites like Groupon and Living Social, Big Skinny could embrace the huge influx of customers that it brings. According to the customer satisfaction and analytics company ForeSee, 91% of customers have already or plan to conduct business with the merchant since buying the deal (Bedigian, 2013). This strategy generates a large influx of customers in a short time while attempting to generate residual income by repeat customers. The cons of this are that companys often lose money during the initial Groupon. The product is discounted by 50% or more and then Groupon takes a 50% commission on the sale price, which leaves the seller receiving only 25% of the original selling price of the item (which in some cases is less than the cost of the item). Forbes has found that 1/3rd of businesses have lost money on a Groupon deal and there is no guarantee that the customers ever return to pay full price from the merchant again (Gleeson, 2012).4. The pros of using a more traditional advertising medium such as TV or radio would bring brand recognition for Big Skinny. Big Skinny has always had success selling in retail stores because they market their products based on value and impulse. By putting the product in more retail stores, there is a greater chance people will put it in their hands and buy on impulse. Instead of targeting just one bi g audience, Big Skinny should advertise by target market such as Big Skinny Sport or Big Skinny Women. By doing this they could partner with big retail chains to get into more stores and generate more revenue the old fashioned way. The average time an American spends watching TV is 5 hours compared to just 1 hour browsing the internet, which leads for greater exposure. The cons of doing this are that TV advertising is much more expensive than online marketing (Nielsen, 1997). Another con is Tivo allows people to record their favorite shows and then fast-forward past the commercials. The last con is that TV advertising seems to be a thing of the past, as the amount spent on TV advertising was only up 4.5% in 2011 as compared to 21.7% via online marketing (Gleeson, 2012).RecommendationsBased on the data, it is best for Big Skinny to be more selective of their online distribution, while tailoring their paid sponsored searches to generate interest and sales. In regards to online distrib ution, Big Skinny should keep eBay and Amazon, however, should drop deep-discount sites such as Groupon or Living Social. To offer a Groupon deal, Big Skinny is guaranteed to be taking a loss. To be eligible to offer a Groupon, Big Skinny must discount the price of their wallet by at least 50%. This turns a $20 wallet into a $10 wallet. Groupon takes a commission of 50% on the sale price, which leaves Big Skinny walking away with only $5 for any wallet sold (Bice, 2012). Essentially, they are taking a loss with every wallet they sell on Groupon. The goal of a Groupon is to try and get repeat customers however, the people that use Groupon are bargain-hunters. They wont return to Big Skinny, but rather, they will return to Groupon again looking for another bargain deal. By using Groupon, Big Skinny also decreases the value of their brand (Gibbard, 2011). Why would a customer pay full price for a $40 wallet when they just bought it on Groupon for $15 or $20 just a short time ago? In kick inition to dropping Groupon, Big Skinny needs to manage their online distribution better because of customer satisfaction issues.On the review site Yelp, Big Skinnys wallets are only receiving a rating of 2.5 out of 5 stars. A lot of the reviews include gripes about not receiving their order for 3-4 weeks or non-existent customer service (most of the negative reviews are from users who bought a Big Skinny wallet on Groupon). If the online distributor doesnt ship your product in a timely manner, your company risks a tarnished reputation. Whether Big Skinny didnt have enough stock to fulfill orders or whether Groupon didnt ship the products in a timely manner, Big Skinny is taking the eliminate and abuse from customers. When people do research for a product they are going to see Big Skinnys products with poor ratings. These poor ratings can scare potential customers away. Big Skinny should only use Amazon, eBay and their website to sell their wallets. This allows them to manage their inventory, not get behind on orders and make sure their product gets shipped in a timely manner. Big Skinny has excellent Amazon ratings and should continue to grow their product through the sterling reputation of Amazon. They should sell the product for a higher price on their website so that people are encouraged to buy through Amazon. This is a win-win for Big Skinny because if people buy through Amazon then Big Skinny doesnt have to waste time and effort fulfilling and shipping orders. If they choose to buy direct than Big Skinny receives a larger profit on their wallets.Lastly, Big Skinny needs to tailor their sponsored keyword searches. They need to eliminate the term leather wallet. They dont manufacture a true leather wallet and the cost per conversion for this keyword is a sky-high $20.26. Big Skinny should also bid less for the term thinnest wallet. The cost per conversion for thinnest wallet also has a high cost, which is $10.53. After replacing leather wallet and l owering the bid for thinnest wallet, Big Skinny should add keywords centered on holidays. Wallets are popular gifts on occasions such as Fathers Day and Christmas. Big Skinny should add season keywords such as Fathers Day Wallet, Wallet for Dad, Best Wallet for Gift and Wallet for Christmas. This will bring seasonal shoppers into the mix who are looking to spend quickly and impulsively.Action and Implementation PlanCEO Kiril Alexandrov will be responsible for delegating the following tasks. The Director of Marketing will pull any promotions or future plans with deep discounted sites such as Groupon or Living Social. The Director of Marketing in combination with the Director of harvest-home Management will reach out to all of those who left negative reviews on Yelp to satisfy the customer complaints and retract the negative ratings. The Director of gross revenue will carefully select the online distribution channels which Big Skinny will sell through. Big Skinny will only sell throu gh Amazon, eBay and any online outlets of the retail stores that they are currently featured in. The Director of Sales will also raise the prices of wallets on the Big Skinny Website by 10-15% to create value for the product and promote customers to purchase through the select online distribution. Doing this saves Big Skinny the time it would take to fulfill and pack orders, however, if a customer decides to purchase direct, then Big Skinny recoups the 10-15% it would pay Amazon or eBay to sell and fulfill the order. This new price point will be conveyed in a message from the Director of Sales to Big Skinnys distribution channel.ReferencesBedigian, L. (2013).

PZT Material for Excessive Vibration

PZT Material for Excessive VibrationIn this regard it is designed and implemented a robust control technique to suppress excessive shaking and also get along health supervise of a structure using a wholeness piece of PZT material. The main idea is to use sliding elbow room controller to achieve the vibration suppression, impedance-based structural health supervise technique, and to implement sliding mode observer to prevent any undesirable interaction between the health monitoring system and the control system, when they are implemented together. The usage of smart materials to perform nondestructive assessment of structures is of great interest to civil engineering and other engineering fields, since the integrity of the structure is not compromised. In addition, the modern each day to a greater ex ext flexible structures bring to interrogationers in the field the need to find alternatives in vibration suppression. Implementing health monitoring together with vibration cont rol is therefore the junto of these two need in a practical and economic manner, in the sense that uses the smart materials and control devices/techniques.Smart materials have the ability of changing their properties when subjected to certain external conditions, such as electric or magnetic fields, for example. In this study the smart material used is in the form of piezoelectric patches. The health monitoring technique used in this research is the impedance-based health monitoring, which is based in changes in the structural impedance. The fundamental idea of this approach is to screen the changes in structural mechanical impedance brought on by damage. An experimental set up was performed in a free-free aluminum bar in order to drive out the applicability of this method. In this experiment, five pairs of PZT patches had been attached to the bar and an electrical impedance analyzer measured the electrical impedance. Damage was simulated by attaching two ten millimeters bolts be tween the third and the fourth PZT patch. As far as the control technique goes, it is implemented a sliding mode controller, which is designed to attain a robust vibration control performance in the movement of the uncertainties and disturbances.Sliding mode control is a nonlinear control strategy that adjusts the dynamics of a nonlinear system by forcing the system to slide alongside a surface of the systems regular behavior. One problem this study has to deal with is the health monitoring signal that enters the feedback control loop, since the same PZT patch is used to simultaneously perform health monitoring and to sense the control system in the feedback control loop. In order to try to solve this issue, a sliding mode observer is designed. In order to evaluate the feasibility of the method proposed, both experimental and numeral studies were performed to a single cantilever shine. The controller and observer were designed based on the four lower vibration modes of the beam.T he experimental set-up performed to assess the impedance-based health monitoring technique showed that a great change in impedance happens in the region where damage occurs. The experimental and numerical results showed the sliding mode observer was undefended of filter the high frequency content that comes from the health monitoring, and the sliding mode control was able to suppress successfully the excessive vibration even after disturbances were introduced. The results from both numerical study and experimental set-up show that this integrated approach can provide significant vibration suppression, while simultaneously detecting damage.The research is important in the sense that brings together the concepts of health monitoring and structural control, and confirms the feasibility of this using sliding mode control/observer and impedance-based health monitoring. However, the study has that are some weaknesses, for example, not much detail is providing regarding the health monitor ing of the experimental set-up of the cantilever beam, only vibration suppression results. Also, is not very wee-wee if the results shown are from experimental or analytical evaluation. Only impulse response was verified in this study, and it would be interesting to see how the control behaves in the presence of different types of more complex loads, such as seismic. It is not practical or economically possible to use 4 to 5 PZT patches to every beam a complex civil engineering structure, so the study fails to address how to choose the location of the patches so they can be enough to suppress vibration and detect damage to a more complex structure, such as a building.

Types of Security Threats and Protection Against Them

Types of Security Threats and aegis A invitest ThemIntroduction musical composition endeavours on calculating machines by outside intruders argon to a greater extent publicized, attacks perpetrated by insiders argon genuinely common land and often more damaging. Insiders re mystify the superior bane to estimator warrantor be vitrine they infrastand their organizations wrinkle and how their computer dodges work. They draw two(prenominal) the confidentiality and nark to perform these attacks.An inside attacker will have a higher opportunity of successfully disruption into the clay and extracting slender learning. The insiders besides act the greatest ch totallyenge to securing the comp each entangle ment because they be authorized a level of penetration to the register system and granted a degree of trust.A system administrator angered by his diminished role in a thriving defense manufacturing firm whose computer ne dickensrk he al unity had developed and man aged, centralized the softwargon that fighted the comp alls manufacturing processes on a single emcee, and then intimidated a coworker into large him the only(prenominal) backup tapes for that softw ar.Following the system administrators termination for inappropriate and black treatment of his coworkers, a logic bomb antecedently set by the insider detonated, deleting the only rebrinying copy of the critical softw atomic number 18 from the accompanys server. The company estimated the cost of rail at in excess of $10 million, which light-emitting diode to the layoff of few 80 employees.An application developer, who lost his IT sector job as a guide of company downsizing, expressed his displeasure at being put off just prior to the Christmas holidays by launching a systematic attack on his former employers computer internet. Three weeks following his termination, the insider employ the username and password of one of his former coworkers to gain remote rile to the net work and modify some(prenominal) of the companys web pages, changing text and inserting sexy images.He also sent each of the companys customers an email message advising that the website had been hacked. separately email message also contained that customers usernames and passwords for the website. An investigating was initiated, neverthe slight(prenominal) it failed to learn the insider as the culprit. A month and a half later, he again remotely accessed the network, executed a script to reset all network passwords and changed 4,000 pricing records to reflect bogus tuition. This former employee ultimately was determine as the perpetrator and prosecuted. He was sentenced to serve five months in prison and two years on supervised probation, and ordered to pay $48,600 restitution to his former employer.A urban center organization employee who was passed over for promotion to finance director retaliated by deleting files from his and a coworkers computers the day before the red-hot finance director took office. An investigation identified the disgruntled employee as the perpetrator of the calamity. City government officials disagreed with the main(a) police detective on the font as to whether all of the set offd files were recovered.No criminal charges were filed, and, under an agreement with city officials, the employee was allowed to resign.These incidents of sabotage were all pull by insiders individuals who were, or previously had been, authorized to use the selective information systems they eventually employed to perpetrate harm. Insiders bugger off a substantial curse by virtue of their fellowship of, and access to, employer systems and/or databases. Keeney, M., et al (2005)The Nature of Security ThreatsThe greatest flagellum to computer systems and information comes from humans, through actions that argon either malicious or unbelieving 3 . Attackers, trying to do harm, exploit vulnerabilities in a system or aegis policy employin g various methods and tools to farm over their aims. Attackers usually have a motive to disrupt normal business operations or to steal information.The supra diagram is depicts the types of gage holy terrors that exist. The diagram depicts the all threats to the computer systems but main emphasis will be on malicious insiders. The greatest threat of attacks against computer systems are from insiders who know the codes and trade protection measures that are in place 45. With very specific objectives, an insider attack can affect all components of aegis. As employees with legitimate access to systems, they are familiar with an organizations computer systems and applications.They are believably to know what actions cause the to the highest degree damage and how to get away with it undetected. Considered members of the family, they are often above suspicion and the last to be considered when systems malfunction or fail. disgruntle employees create mischief and sabotage against systems. Organizational downsizing in both public and esoteric sectors has created a group of individuals with significant knowledge and capabilities for malicious activities 6 and revenge. Contract professionals and foreign nationals either brought into the U.S. on work visas to meet labor shortages or from offshore outsourcing projects are also included in this category of learned insiders.Common Insider ThreatCommon cases of computer- associate employee sabotage include changing data deleting data destroying data or programs with logic bombs crashing systems holding data hostage destroying hardware or facilities entering data incorrectly, exposing sensitive and embarrassing proprietary data to public slang such(prenominal)(prenominal) as the salaries of top executives. Insiders can plant viruses, trojan horses or worms, browse through file systems or program malicious code with superficial chance of detection and with al or so total impunity.A 1998 FBI go over 7 investi gating computer crime found that of the 520 companies consulted, 64% had accountinged security breaches for a total quantifiable fiscal loss of $136 millions. (See chart)The survey also found that the largest number of breaches were by unauthorized insider access and concluded that these figures were very conservative as to the highest degree companies were unaware of malicious activities or reluctant to report breaches for fear of negative press. The survey reported that the average cost of an attack by an alien (hacker) at $56,000, go the average insider attack cost a company excess $2.7 million. It found that hidden costs associated with the loss in staff hours, juristic liability, loss of proprietary information, decrease in productivity and the potence loss of credibility were impossible to quantify entirely.Employees who have caused damage have used their knowledge and access to information resources for a range of motives, including greed, revenge for comprehend grieva nces, ego gratification, resolution of personal or professional bothers, to protect or advance their careers, to quarrel their skill, express anger, impress others, or some combination of these concerns.Insider CharacteristicsThe majority of the insiders were former employees.At the time of the incident, 59% of the insiders were former employees or contractors of the affected organizations and 41% were flow employees or contractors.The former employees or contractors leftover their positions for a mixing of reasons. These included the insiders being fired (48%), resigning (38%), and being laid off (7%). Most insiders were either previously or latestly employed full-time in a technical position within the organization.Most of the insiders (77%) were full-time employees of the affected organizations, either before or during the incidents. Eight per centum of the insiders worked part-time, and an additional 8% had been hired as contractors or consultants. Two (4%) of the insid ers worked as temporary employees, and one (2%) was hired as a subcontractor.lxxxvi percent of the insiders were employed in technical positions, which included system administrators (38%), programmers (21%), engineers (14%), and IT specialists (14%). Of the insiders non holding technical positions, 10% were employed in a professional position, which included, among others, insiders employed as editors, managers, and auditors. An additional two insiders (4%) worked in service positions, both of whom worked as customer service representatives.Insiders were demographically varied with regard to age, racial and ethnic background, gender, and marital status.The insiders ranged in age from 17 to 60 years (mean age = 32 years)17 and represented a variety of racial and ethnic backgrounds.Ninety-six percent of the insiders were male.Forty-nine percent of the insiders were married at the time of the incident, while 45% were single, having neer married, and 4% were divorced. Just under one- trine of the insiders had an arrest history.Thirty percent of the insiders had been arrested previously, including arrests for violent offenses (18%), alcohol or drug related offenses (11%), and nonfiscal/ fraud related theft offenses (11%).Organization CharacteristicsThe incidents affected organizations in the following critical fundament sectorsBanking and finance (8%) perseverance of government (16%)Defense industrial base (2%)Food (4%) selective information and telecommunications (63%)Postal and shipping (2%)Public health (4%)In all, 82% of the affected organizations were in privy attention, while 16% were government entities. Sixty-three percent of the organizations active in domestic natural action only, 2% engaged in international application only, and 35% engaged in activity both domestically and internationally.What strike insiders?Internal attackers attempt to break into computer networks for many reasons. The subject has been fruitfully studied and essential atta ckers are used to be motivate with the following reasons BSB03 challengeMany internal attackers initially attempt to break into networks for the challenge. A challenge combines strategic and tactical thinking, patience, and mental strength. However, internal attackers motivate by the challenge of breaking into networks often do not often think active their actions as criminal. For example, an internal attack can be the challenge to break into the mail server in order to get access to antithetic emails of any employee.RevengeInternal attackers motivated by revenge have often ill feelings toward employees of the homogeneous company. These attackers can be particularly dangerous, because they mostly focus on a single target, and they generally have patience. In the case of revenge, attackers can also be former employees that feel that they have been wrongfully fired. For example, a former employee may be motivated to launch an attack to the company in order to cause financial losse s.EspionageInternal attackers motivated by espionage, steal confidential information for a third party. In general, two types of espionage existsIndustrial espionageIndustrial espionage means that a company may pay its own employees in order to break into the networks of its competitors or business partners. The company may also hire someone else to do this.International espionageInternational espionage means that attackers work for governments and steal confidential information for other governments.Definitions of insider threat1) The definition of insider threat should encompass two main threat actor categories and five general categories of activities. The commencement exercise actor category, the true insider, is defined as any entity (person, system, or code) authorized by command and ensure elements to access network, system, or data. The second actor category, the pseudo-insider, is someone who, by policy, is not authorized the accesses, roles, and/or permissions they short ly have but may have gotten them inadvertently or through malicious activities.The activities of both fall into five general categoriesExceeds given network, system or data permissionsConducts malicious activity against or across the network, system or dataProvided unapproved access to the network, system or dataCircumvents security controls or exploits security weaknesses to exceed authorized permitted activity or disguise chance on orNon-maliciously or unknowledgeablely damages resources (network, system or data) by destruction, corruption, denial of access, or disclosure.(Presented at the University of Louisville Cyber Securitys Day, October 2006)2) Insiders employees, contractors, consultants, and vendors pose as great a threat to an organizations security posture as outsiders, including hackers. Few organizations have implemented the policies, procedures, tools, or strategies to effectively address their insider threats. An insider threat assessment is a recommended first s tep for many organizations, followed by policy review, and employee awareness training.(Insider Threat ManagementPresented by infoLock Technologies)3) Employees are an organizations most important asset. Unfortunately, they also present the greatest security risks. Working and communicating remotely, storing sensitive data on portable devices such as laptops, PDAs, thumb drives, and even iPods employees have extended the security perimeter beyond safe limits. While convenient access to data is required for operative efficiency, the actions of trusted insiders not just employees, but consultants, contactors, vendors, and partners must be actively managed, audited, and monitored in order to protect sensitive data.(Presented by infoLock Technologies)4) The diversity of cyber threat has grown over time from network-level attacks and password cracking to include forward-lookinger classes such as insider attacks, email worms and social engineering, which are currently recognized as s erious security problems. However, attack modeling and threat analysis tools have not evolved at the same rate. Known formal models such as attack graphs perform action-centric vulnerability modeling and analysis. All possible atomic user actions are represented as states, and sequences which lead to the violation of a specie safety property are extracted to indicate possible exploits.(Ramkumar Chinchani, Anusha Iyer, Hung Ngo, Shambhu Upadhyaya)5) The Insider Threat scan, conducted by the U.S. Secret gain and Carnegie Mellon Universitys Software Engineering Institute CERT Program, analyzed insider cyber crimes across U.S. critical infrastructure sectors. The try indicates that charge decisions related to organizational and employee performance sometimes bring back unintended consequences magnifying risk of insider attack. Lack of tools for understanding insider threat, analyzing risk mitigation alternatives, and communicating settlements exacerbates the problem.(Dawn M. Cappe lli, Akash G. Desai)6) The insider threat or insider problem is cited as the most serious security problem in many studies. It is also considered the most difficult problem to deal with, because an insider has information and capabilities not cognize to other, external attackers. But the studies rarely define what the insider threat is, or define it nebulously. The difficulty in handling the insider threat is reasonable under those dower if one cannot define a problem precisely, how can one approach a solution, let alone know when the problem is solved?(Matt Bishop 2005)Five common insider threatExploiting information via remote access softwareA considerable amount of insider abuse is performed offsite via remote access software such as closing Services, Citrix and GoToMyPC. Simply put, users are less likely to be caught take sensitive information when they can it do offsite. Also, inadequately protected remote computers may turn up in the hands of a third-party if the computer is left unattended, lost or stolen.2.) Sending out information via e-mail and wink messaging afflictive information can simply be included in or attached to an e-mail or IM. Although this is a serious threat, its also one of the easiest to eliminate.3.) communion sensitive files on P2P networksWhether or not you allow peer-to-peer file sharing software such as Kazaa or IM on your network, odds are its at that place and waiting to be abused. The inanimate software in and of itself is not the problem its how its used that causes trouble. All it takes is a simple misconfiguration to serve up your networks local and network drives to the world.4.) Careless use of wireless networksPerhaps the most unintentional insider threat is that of insecure wireless network usage. Whether its at a coffee shop, airport or hotel, unsecured airwaves can easily put sensitive information in jeopardy. All it takes is a peek into e-mail communications or file transfers for valuable data to be stolen. Wi-Fi networks are most susceptible to these attacks, but dont over number Bluetooth on smartphones and PDAs. Also, if you have WLANs inside your organization, employees could use it to exploit the network after hours.5.) circuit board information to discussion boards and blogsQuite often users post support requests, blogs or other work-related messages on the Internet. Whether intentional or not, this can include sensitive information and file attachments that put your organization at risk.Views of different authors to the highest degree insider threat1) Although insiders in this report tended to be former technical employees, there is no demographic profile of a malicious insider. Ages of perpetrators ranged from late teens to retirement. Both men and women were malicious insiders. Their positions included programmers, graphic artists, system and network administrators, managers, and executives. They were currently employed and recently over(p) employees, contractors, and tempo rary employees. As such, security awareness training involve to encourage employees to identify malicious insiders by behavior, not by stereotypical characteristics. For example, behaviors that should be a source of concern include making threats against the organization, bragging about the damage one could do to the organization, or discussing plans to work against the organization. Also of concern are attempts to gain other employees passwords and to double-tonguedly obtain access through prevarication or exploitation of a trusted relationship.Insiders can be stopped, but stopping them is a building complex problem. Insider attacks can only be prevented through a layered defense strategy consisting of policies, procedures, and technical controls. Therefore, management must pay close circumspection to many aspects of its organization, including its business policies and procedures, organizational culture, and technical environment. Organizations must look beyond information tech nology to the organizations overall business processes and the interplay between those processes and the technologies used.(Michelle Keeney, J.D., Ph.D. atal 2005)2) While attacks on computers by outside intruders are more publicized, attacks perpetrated by insiders are very common and often more damaging. Insiders represent the greatest threat to computer security because they understand their organizations business and how their computer systems work. They have both the confidentiality and access to perform these attacks. An inside attacker will have a higher probability of successfully breaking into the system and extracting critical information. The insiders also represent the greatest challenge to securing the company network because they are authorized a level of access to the file system and granted a degree of trust.(Nam Nguyen and nib Reiher, Geoffrey H. Kuenning)3) Geographically distributed information systems achieve high availability that is crucial to their usefulness by replicating their state. Providing instant access at time of pauperization regardless of current network connectivity requires the state to be replicated in every geographical site so that it is topically available. As network environments become increasingly hostile, we have to fool that part of the distributed information system will be compromised at some point. The problem of maintaining a replicated state in such a system is enlarged when insider (or Byzantine) attacks are taken into account.(Yair Amir Cristina Nita-Rotaru)4) In 2006, over 60% of information security breaches were referable to insider behavior, yet more than 80% of corporate IT security budgets were played out on securing perimeter defenses against outside attack. Protecting against insider threats means managing policy, process, technology, and most importantly, people. Protecting against insider threats means managing policy, process, technology, and most importantly, people.The Insider Threat Assessm ent security awareness training, infrastructure reconfiguration, or third party solutions, you can take comfort in knowing that you have make the right choice to improve your security posture, and you will achieve your expected Return on Security Investment.(Presented by infoLock Technologies)5) The threat of attack from insiders is real and substantial. The 2004 ECrime read Survey TM conducted by the United States Secret Service, CERT Coordination aggregate (CERT/CC), and CSO Magazine, 1 found that in cases where respondents could identify the perpetrator of an electronic crime, 29 percent were committed by insiders. The impact from insider attacks can be devastating. One complex case of financial fraud committed by an insider in a financial intromission resulted in losses of over $600 million. 2 Another case involving a logic bomb written by a technical employee working for a defense contractor resulted in $10 million in losses and the layoff of 80 employees.(Dawn Cappelli, And rew Moore, Timothy Shimeall,2005)6) Insiders, by virtue of legitimate access to their organizations information, systems, and networks, pose a significant risk to employers. Employees experiencing financial problems have found it idle to use the systems they use at work everyday to commit fraud. Other employees, motivated by financial problems, greed, or the wish to impress a new employer, have stolen confidential data, proprietary information, or intellectual property from their employer. Lastly, technical employees, possibly the most dangerous because of their intimate knowledge of an organizations vulnerabilities, have used their technical ability to sabotage their employers system or network in revenge for some negative work-related event.(Dawn M. Cappelli, Akash G. Desai ,at al 2004)7) The insider problem is considered the most difficult and critical problem in computer security. But studies that survey the distressfulness of the problem, and enquiry that analyzes the problem , rarely define the problem precisely. Implicit definitionsvary in meaning. Different definitions imply different countermeasures, as strong as different assumptions.(Matt Bishop 2005)Solution user monitoringInsiders have two things that external attackers dont privileged access and trust. This allows them to bypass preventative measures, access mission-critical assets, and conduct malicious acts all while flying under the radar unless a strong incident detection solution is in place.A number of variables motivate insiders, but the end result is that they can more easily perpetrate their crimes than an outsider who has special access. Insiders can directly damage your business resulting in lost revenue, lost customers, reduced shareowner faith, a tarnished reputation, regulatory fines and legal fees. With such an expansive threat, organizations need an automated solution to help detect and analyzeMalicious Insider ActivityThese are some points which could be helpful in monitorin g and minimizing the insider threatsDetecting insider activity starts with an expanded logand event collection.Firewalls, routers and intrusion detection systems are important, but they are not enough.Organizations need to look deeper to include mission critical applications such as email applications, databases, operating systems, mainframes, access control solutions, physical security systems as well as identity and content management products.Correlation identifying known types of suspicious and malicious behaviorAnomaly detection recognizing deviations from norms and baselines.Pattern discovery uncovering apparently unrelated events that show a pattern of suspicious activityFrom case management, event annotation and escalation to reporting, auditing and access to insider-relevant information, the technical solution must be in line with the organizations procedures. This will vouch that insiders are addressed consistently, efficiently and effectively regardless of who they are. Identify suspicious user activity patterns and identify anomalies.Visually track and create business-level reports on users activity.Automatically escalate the threat levels of suspicious and malicious individuals.Respond according to your specific and uncommon corporate governing guidelines.Early detection of insider activity establish on early warning indicators of suspicious behavior, such asStale or over(p) accountsExcessive file printing, unusual printing times andkeywords printed duty to suspicious destinationsUnauthorized peripheral device accessBypassing security controlsAttempts to alter or delete system logsInstallation of malicious softwareThe Insider Threat Study?The global acceptance, business adoption and growth of the Internet, and of Internetworking technologies in general, in response to customer requests for online access to business information systems, has ushered in an extraordinary expansion of electronic business transactions. In moving from internal (closed ) business systems to open systems, the risk of malicious attacks and fraudulent activity has increased enormously, thereby requiring high levels of information security. precedent to the requirement for online, open access, the information security budget of a typical company was less then their tea and coffee expenses.Securing cyberspace has become a national priority. In The National Strategy to Secure Cyberspace, the Presidents Critical root Protection Board identified several critical infrastructure sectors10banking and financeinformation and telecommunicationstransportationpostal and shippingemergency servicescontinuity of governmentpublic healthUniversitieschemical industry, textile industry and angry materialsagriculturedefense industrial baseThe cases examined in the Insider Threat Study are incidents perpetrated by insiders (current or former employees or contractors) who intentionally exceeded or utilise an authorized level of network, system, or data access in a mann er that affected the security of the organizations data, systems, or daily business operations.Incidents included any compromise, manipulation of, unauthorized access to, exceeding authorized access to, tampering with, or disenable of any information system, network, or data. The cases examined also included any in which there was an unauthorized or illegal attempt to view, disclose, retrieve, delete, change, or add information.A completely secure, aught risk system is one which has zero functionality. Latest technology high-performance automated systems bring with them new risks in the shape of new attacks, new viruses and new software bugs, etc. IT Security, therefore, is an ongoing process. decorous risk management keeps the IT Security plans, policies and procedures up to date as per new requirements and changes in the computing environment. To implement controls to counter risks requires policies, and policy can only be implemented successfully if the top management is comm itted. And policys effective implementation is not possible without the training and awareness of staff.The State Bank of Pakistan recognizes that financial industry is built around the sanctity of the financial transactions. Owing to the critical role of financial institutions for a country and the extreme sensitivity of their information assets, the seriousness of ITSecurity and the ever-increasing threats it faces in todays open world cannot be overstated. As more and more of our Banking Operations and products services become technology impelled and dependent, consequently our reliance on these technology assets increases, and so does the need to protect and safeguard these resources to ensure smooth mathematical process of the financial industry.Here are different area in which we can work and check insider threat, but I chose textile industry as in textile industry there is less awareness of the insider threat. If an insider attack in an industry then industrialist try to c over up this intelligence agency as these types of news about an industry can damage the reputation of the industry.Chapter 2 Review of LiteratureS, Axelsson. ,(2000)Anonymous 2001Continuity of operations and correct functioning of information systems is important to most businesses. Threats to computerised information and process are threats to business quality and effectiveness. The objective of IT security is to put measures in place which eliminate or reduce significant threats to an acceptable level.Security and risk management are tightly coupled with quality management. Security measures should be implemented based on risk analysis and in harmony with Quality structures, processes and checklists.What needfully to be protected, against whom and how?Security is the protection of information, systems and services against disasters, mistakes and manipulation so that the likelihood and impact of security incidents is minimised. IT security is comprised ofConfidentiality Sensitiv e business objects (information processes) are disclosed only to authorised persons. == Controls are required to restrict access to objects.Integrity The business need to control modification to objects (information and processes). == Controls are required to ensure objects are accurate and complete.Availability The need to have business objects (information and services) available when needed. == Controls are required to ensure dependableness of services.Legal Compliance Information/data that is collected, processed, used, passed on or destroyed must be handled in line with current legislation of the relevant countries.A threat is a danger which could affect the security (confidentiality, integrity, availability) of assets, tether to a potential loss or damage.Stoneburner et al (2002)In this paper the author draw a the risks which areTypes of Security Threats and Protection Against ThemTypes of Security Threats and Protection Against ThemIntroductionWhile attacks on computers b y outside intruders are more publicized, attacks perpetrated by insiders are very common and often more damaging. Insiders represent the greatest threat to computer security because they understand their organizations business and how their computer systems work. They have both the confidentiality and access to perform these attacks.An inside attacker will have a higher probability of successfully breaking into the system and extracting critical information. The insiders also represent the greatest challenge to securing the company network because they are authorized a level of access to the file system and granted a degree of trust.A system administrator angered by his diminished role in a thriving defense manufacturing firm whose computer network he alone had developed and managed, centralized the software that supported the companys manufacturing processes on a single server, and then intimidated a coworker into giving him the only backup tapes for that software.Following the sys tem administrators termination for inappropriate and abusive treatment of his coworkers, a logic bomb previously planted by the insider detonated, deleting the only remaining copy of the critical software from the companys server. The company estimated the cost of damage in excess of $10 million, which led to the layoff of some 80 employees.An application developer, who lost his IT sector job as a result of company downsizing, expressed his displeasure at being laid off just prior to the Christmas holidays by launching a systematic attack on his former employers computer network. Three weeks following his termination, the insider used the username and password of one of his former coworkers to gain remote access to the network and modify several of the companys web pages, changing text and inserting pornographic images.He also sent each of the companys customers an email message advising that the website had been hacked. Each email message also contained that customers usernames and passwords for the website. An investigation was initiated, but it failed to identify the insider as the perpetrator. A month and a half later, he again remotely accessed the network, executed a script to reset all network passwords and changed 4,000 pricing records to reflect bogus information. This former employee ultimately was identified as the perpetrator and prosecuted. He was sentenced to serve five months in prison and two years on supervised probation, and ordered to pay $48,600 restitution to his former employer.A city government employee who was passed over for promotion to finance director retaliated by deleting files from his and a coworkers computers the day before the new finance director took office. An investigation identified the disgruntled employee as the perpetrator of the incident. City government officials disagreed with the primary police detective on the case as to whether all of the deleted files were recovered.No criminal charges were filed, and, under an agreement with city officials, the employee was allowed to resign.These incidents of sabotage were all committed by insiders individuals who were, or previously had been, authorized to use the information systems they eventually employed to perpetrate harm. Insiders pose a substantial threat by virtue of their knowledge of, and access to, employer systems and/or databases. Keeney, M., et al (2005)The Nature of Security ThreatsThe greatest threat to computer systems and information comes from humans, through actions that are either malicious or ignorant 3 . Attackers, trying to do harm, exploit vulnerabilities in a system or security policy employing various methods and tools to achieve their aims. Attackers usually have a motive to disrupt normal business operations or to steal information.The above diagram is depicts the types of security threats that exist. The diagram depicts the all threats to the computer systems but main emphasis will be on malicious insiders. The greatest thr eat of attacks against computer systems are from insiders who know the codes and security measures that are in place 45. With very specific objectives, an insider attack can affect all components of security. As employees with legitimate access to systems, they are familiar with an organizations computer systems and applications.They are likely to know what actions cause the most damage and how to get away with it undetected. Considered members of the family, they are often above suspicion and the last to be considered when systems malfunction or fail. Disgruntled employees create mischief and sabotage against systems. Organizational downsizing in both public and private sectors has created a group of individuals with significant knowledge and capabilities for malicious activities 6 and revenge. Contract professionals and foreign nationals either brought into the U.S. on work visas to meet labor shortages or from offshore outsourcing projects are also included in this category of kn owledgeable insiders.Common Insider ThreatCommon cases of computer-related employee sabotage include changing data deleting data destroying data or programs with logic bombs crashing systems holding data hostage destroying hardware or facilities entering data incorrectly, exposing sensitive and embarrassing proprietary data to public view such as the salaries of top executives. Insiders can plant viruses, Trojan horses or worms, browse through file systems or program malicious code with little chance of detection and with almost total impunity.A 1998 FBI Survey 7 investigating computer crime found that of the 520 companies consulted, 64% had reported security breaches for a total quantifiable financial loss of $136 millions.

It found that hidden costs associated with the loss in staff hours, legal liability, loss of proprietary information, decrease in productivity and the potential loss of credibility were impossible to quantify accurately.Employees who have caused damage have used their knowledge and access to information resources for a range of motives, including greed, revenge for perceived grievances, ego gratification, resolution of personal or professional problems, to protect or advance their careers, to challenge their skill, express anger, impress others, or some combination of these concerns.Insider CharacteristicsThe majority of the insiders were former employees.At the time of the incident, 59% of the insiders were former employees or contractors of the affected organizations and 41% were current employees or contracto rs.The former employees or contractors left their positions for a variety of reasons.

Whether intentional or not, this can include sensitive information and file attachments that put your organization at risk.Views of different authors abo ut insider threat1) Although insiders in this report tended to be former technical employees, there is no demographic profile of a malicious insider. Ages of perpetrators ranged from late teens to retirement. Both men and women were malicious insiders. Their positions included programmers, graphic artists, system and network administrators, managers, and executives. They were currently employed and recently terminated employees, contractors, and temporary employees. As such, security awareness training needs to encourage employees to identify malicious insiders by behavior, not by stereotypical characteristics. For example, behaviors that should be a source of concern include making threats against the organization, bragging about the damage one could do to the organization, or discussing plans to work against the organization. Also of concern are attempts to gain other employees passwords and to fraudulently obtain access through trickery or exploitation of a trusted relationship.I nsiders can be stopped, but stopping them is a complex problem. Insider attacks can only be prevented through a layered defense strategy consisting of policies, procedures, and technical controls. Therefore, management must pay close attention to many aspects of its organization, including its business policies and procedures, organizational culture, and technical environment. Organizations must look beyond information technology to the organizations overall business processes and the interplay between those processes and the technologies used.(Michelle Keeney, J.D., Ph.D. atal 2005)2) While attacks on computers by outside intruders are more publicized, attacks perpetrated by insiders are very common and often more damaging. Insiders represent the greatest threat to computer security because they understand their organizations business and how their computer systems work. They have both the confidentiality and access to perform these attacks. An inside attacker will have a higher pr obability of successfully breaking into the system and extracting critical information. The insiders also represent the greatest challenge to securing the company network because they are authorized a level of access to the file system and granted a degree of trust.(Nam Nguyen and Peter Reiher, Geoffrey H. Kuenning)3) Geographically distributed information systems achieve high availability that is crucial to their usefulness by replicating their state. Providing instant access at time of need regardless of current network connectivity requires the state to be replicated in every geographical site so that it is locally available. As network environments become increasingly hostile, we have to assume that part of the distributed information system will be compromised at some point. The problem of maintaining a replicated state in such a system is magnified when insider (or Byzantine) attacks are taken into account.(Yair Amir Cristina Nita-Rotaru)4) In 2006, over 60% of information sec urity breaches were attributable to insider behavior, yet more than 80% of corporate IT security budgets were spent on securing perimeter defenses against outside attack. Protecting against insider threats means managing policy, process, technology, and most importantly, people. Protecting against insider threats means managing policy, process, technology, and most importantly, people.The Insider Threat Assessment security awareness training, infrastructure reconfiguration, or third party solutions, you can take comfort in knowing that you have made the right choice to improve your security posture, and you will achieve your expected Return on Security Investment.(Presented by infoLock Technologies)5) The threat of attack from insiders is real and substantial. The 2004 ECrimeWatch Survey TM conducted by the United States Secret Service, CERT Coordination Center (CERT/CC), and CSO Magazine, 1 found that in cases where respondents could identify the perpetrator of an electronic crime , 29 percent were committed by insiders. The impact from insider attacks can be devastating. One complex case of financial fraud committed by an insider in a financial institution resulted in losses of over $600 million. 2 Another case involving a logic bomb written by a technical employee working for a defense contractor resulted in $10 million in losses and the layoff of 80 employees.(Dawn Cappelli, Andrew Moore, Timothy Shimeall,2005)6) Insiders, by virtue of legitimate access to their organizations information, systems, and networks, pose a significant risk to employers. Employees experiencing financial problems have found it easy to use the systems they use at work everyday to commit fraud. Other employees, motivated by financial problems, greed, or the wish to impress a new employer, have stolen confidential data, proprietary information, or intellectual property from their employer. Lastly, technical employees, possibly the most dangerous because of their intimate knowledge o f an organizations vulnerabilities, have used their technical ability to sabotage their employers system or network in revenge for some negative work-related event.(Dawn M. Cappelli, Akash G. Desai ,at al 2004)7) The insider problem is considered the most difficult and critical problem in computer security. But studies that survey the seriousness of the problem, and research that analyzes the problem, rarely define the problem precisely. Implicit definitionsvary in meaning. Different definitions imply different countermeasures, as well as different assumptions.(Matt Bishop 2005)Solution User monitoringInsiders have two things that external attackers dont privileged access and trust. This allows them to bypass preventative measures, access mission-critical assets, and conduct malicious acts all while flying under the radar unless a strong incident detection solution is in place.A number of variables motivate insiders, but the end result is that they can more easily perpetrate their c rimes than an outsider who has limited access. Insiders can directly damage your business resulting in lost revenue, lost customers, reduced shareholder faith, a tarnished reputation, regulatory fines and legal fees. With such an expansive threat, organizations need an automated solution to help detect and analyzeMalicious Insider ActivityThese are some points which could be helpful in monitoring and minimizing the insider threatsDetecting insider activity starts with an expanded logand event collection.Firewalls, routers and intrusion detection systems are important, but they are not enough.Organizations need to look deeper to include mission critical applications such as email applications, databases, operating systems, mainframes, access control solutions, physical security systems as well as identity and content management products.Correlation identifying known types of suspicious and malicious behaviorAnomaly detection recognizing deviations from norms and baselines.Pattern dis covery uncovering seemingly unrelated events that show a pattern of suspicious activityFrom case management, event annotation and escalation to reporting, auditing and access to insider-relevant information, the technical solution must be in line with the organizations procedures. This will ensure that insiders are addressed consistently, efficiently and effectively regardless of who they are.Identify suspicious user activity patterns and identify anomalies.Visually track and create business-level reports on users activity.Automatically escalate the threat levels of suspicious and malicious individuals.Respond according to your specific and unique corporate governing guidelines.Early detection of insider activity based on early warning indicators of suspicious behavior, such asStale or terminated accountsExcessive file printing, unusual printing times andkeywords printedTraffic to suspicious destinationsUnauthorized peripheral device accessBypassing security controlsAttempts to alte r or delete system logsInstallation of malicious softwareThe Insider Threat Study?The global acceptance, business adoption and growth of the Internet, and of Internetworking technologies in general, in response to customer requests for online access to business information systems, has ushered in an extraordinary expansion of electronic business transactions. In moving from internal (closed) business systems to open systems, the risk of malicious attacks and fraudulent activity has increased enormously, thereby requiring high levels of information security. Prior to the requirement for online, open access, the information security budget of a typical company was less then their tea and coffee expenses.Securing cyberspace has become a national priority. In The National Strategy to Secure Cyberspace, the Presidents Critical Infrastructure Protection Board identified several critical infrastructure sectors10banking and financeinformation and telecommunicationstransportationpostal and s hippingemergency servicescontinuity of governmentpublic healthUniversitieschemical industry, textile industry and hazardous materialsagriculturedefense industrial baseThe cases examined in the Insider Threat Study are incidents perpetrated by insiders (current or former employees or contractors) who intentionally exceeded or misused an authorized level of network, system, or data access in a manner that affected the security of the organizations data, systems, or daily business operations.Incidents included any compromise, manipulation of, unauthorized access to, exceeding authorized access to, tampering with, or disabling of any information system, network, or data. The cases examined also included any in which there was an unauthorized or illegal attempt to view, disclose, retrieve, delete, change, or add information.A completely secure, zero risk system is one which has zero functionality. Latest technology high-performance automated systems bring with them new risks in the shape of new attacks, new viruses and new software bugs, etc. IT Security, therefore, is an ongoing process. Proper risk management keeps the IT Security plans, policies and procedures up to date as per new requirements and changes in the computing environment. To implement controls to counter risks requires policies, and policy can only be implemented successfully if the top management is committed. And policys effective implementation is not possible without the training and awareness of staff.The State Bank of Pakistan recognizes that financial industry is built around the sanctity of the financial transactions. Owing to the critical role of financial institutions for a country and the extreme sensitivity of their information assets, the seriousness of ITSecurity and the ever-increasing threats it faces in todays open world cannot be overstated. As more and more of our Banking Operations and products services become technology driven and dependent, consequently our reliance on these technology assets increases, and so does the need to protect and safeguard these resources to ensure smooth functioning of the financial industry.Here are different area in which we can work and check insider threat, but I chose textile industry as in textile industry there is less awareness of the insider threat. If an insider attack in an industry then industrialist try to cover up this news as these types of news about an industry can damage the reputation of the industry.Chapter 2 Review of LiteratureS, Axelsson. ,(2000)Anonymous 2001Continuity of operations and correct functioning of information systems is important to most businesses. Threats to computerised information and process are threats to business quality and effectiveness. The objective of IT security is to put measures in place which eliminate or reduce significant threats to an acceptable level.Security and risk management are tightly coupled with quality management. Security measures should be implemented based on risk analysis and in harmony with Quality structures, processes and checklists.What needs to be protected, against whom and how?Security is the protection of information, systems and services against disasters, mistakes and manipulation so that the likelihood and impact of security incidents is minimised. IT security is comprised ofConfidentiality Sensitive business objects (information processes) are disclosed only to authorised persons. == Controls are required to restrict access to objects.Integrity The business need to control modification to objects (information and processes). == Controls are required to ensure objects are accurate and complete.Availability The need to have business objects (information and services) available when needed. == Controls are required to ensure reliability of services.Legal Compliance Information/data that is collected, processed, used, passed on or destroyed must be handled in line with current legislation of the relevant countries.A threat is a danger which could affect the security (confidentiality, integrity, availability) of assets, leading to a potential loss or damage.Stoneburner et al (2002)In this paper the author described a the risks which are

Epilepsy Research Paper -- Papers Disorder Health Essays

Epilepsy Research Paper People most often associate red twitching, falling to the floor and drooling with epilepsy. However the described event is only one kind of an epileptic seizure, which is called a tonic-clonic seizure. There are many other kinds of seizures, and all(prenominal) has different sets of signs and symptoms. During generalized seizures the full brain is affected and the initial symptom is loss of consciousness. This category includes such seizures as absence seizure, myoclonic seizure, and atonic attack. Those seizures affect the whole body and brain of the patient, and are much more serious than social functionial or focal seizure, which only affects one muscle or one part of the body, and not accompanied by loss of consciousness. Epilepsy occurs when nerve cells in the brain fire electrical impulses at a rate of up to four time higher than normal. This causes a sort of electrical storm in the brain, known as a seizure. During a s eizure the normal neuronal activity, which is usually liable for human thoughts, feelings, and actions of glands and muscles, becomes disturbed and as a result strange behavior, convulsions and loss of consciousness might occur. Epilepsy knows no geographical, racial or social boundaries. It occurs in hands and women and can begin at any age, but is most frequently diagnosed in childhood or old age. Anyone can be affected by seizures. In fact, up to 5% of the worlds population may have a single seizure at some time in their lives, but a person might be diagnosed with epilepsy only after they had two unprovoked seizures. From many studies around the world it has been estimated that the m... ...mpted to move, chair should be put in irresistible position, everything should be out of the way and passive restraint should be used to prevent patient from hitting anything or falling out of the chair. Emergency assist should be summoned right away. Epilep sy is not contagious and is not caused by mental illness or mental retardation. Many commonwealth with epilepsy have normal or above-average intelligence. Famous people who are known or rumored to have had epilepsy include the Russian writer Dostoyevsky, the philosopher Socrates, the military general Napoleon, and the inventor of dynamite, Alfred Nobel, who established the Nobel prize. Many people with epilepsy lead productive lives. Many medical and research advances in the past two decades have led to a better understanding of epilepsy and seizures than ever before.
