STUXNET - Research Paper Example As the engineer hooked the computer to the Internet, the worm spread far and wide. How the Stuxnet Worm Spread The Stuxnet worm started to spread in March 2010, but it took its first variant about three months from then to appear. As people learnt about the existence of the worm on 15 July 2010, the servers for two mailing lists were attacked with the distributed denial-of-service on the industrial-systems security. Although at that time, the source of attack could not be worked out, yet it was suspected to be the Stuxnet worm. As a result of the attack, one of the two mailing lists got disabled, thus interrupting a very important informative source for the factories and the power plants. Two more variants of the Stuxnet worm surfaced; the first in March 2010 and the second in April 2010. In the authors’ opinion, the second and substantially improved variant showed up because of slow progression of the Stuxnet worm. The third variant that surfaced in April 2010 had only minor improvements. There is a build time-stamp in thee worm that starts from 3 February 2010. According to the report delivered by the Sky News on 25 November 2010 in the United Kingdom, an anonymous source whose IT security organization was also unidentified sent the news to Sky News that the black market had received a variation of the Stuxnet worm, but there was lack of consensus among the security experts over this matter. How the Stuxnet Worm Works Stuxnet makes use of vulnerability just like Windows uses the shortcut files to expand to new systems. The Stuxnet worm’s design was bottom-up so that it could effectively attack the systems implemented for the management of industrial networks like chemical manufacturing facilities and power plants as well as the systems of Supervisory Control and Data Acquisition (SCADA). In the start, the Stuxnet worm was thought to progress through such removable drives as USB sticks. However, about two weeks after the Stuxnet worm was first id entified, researchers of the Kaspersky Lab working in Moscow found that an unknown security flaw in the sharing of printer resources by the Windows could also help the Stuxnet worm spread. Microsoft found a way to fix this vulnerability with MS10-061 which varies in risk from one type of windows to another. â€Å"At least one aspect of what Stuxnet does is to take control of the process and to be able to do†¦whatever the author or programmer wants it to do. This has potentially devastating consequences, and there needs to be a lot more attention focused on it† (Weiss cited in â€Å"‘Stuxnet’ Worm Far†). The Target of the Stuxnet Worm The main target of the Stuxnet worm is the Siemens software. One trait that distinguishes the Stuxnet worm from most viruses that have been identified to date is that it remains silent till the time the worm locates Siemens software in the Windows system. Once the Siemens software is found, the Stuxnet worm exploits up to four 0-day attacks. The Stuxnet worm infected the SCADA systems in 14 functional plants of Siemens, though the infections could not hold the infected plants’ productions. According to the IDG News reports, the Stuxnet worm has infected systems at the Siemens plants in North America, Korea, and the UK, while the maximum infections have so far been made in the plants operating in

Write a Critical Review paper on Students with disabilities enrolled Research

Write a Critical Review on Students with disabilities enrolled at educational institutions at all levels - Research Paper Example On top of that, the lawsuit also alleged that the state of New Jersey had violated its constitutional obligation to oversee the implementation of IDEA requirements at the grassroots; in defense, the state of New Jersey filed a motion to dismiss citing a constitutional challenge to the implementation of the IDEA. According to the state of New Jersey, it was immune to private lawsuits regarding enforcement of the IDEA under the provisions of the Eleventh Amendment but the section of parents were not convinced by this argument. In their earnest search for justice, the section went ahead to seek intervention in defending the constitutionality of IDEA, which was eventually granted to them; in their battle to defend the constitutionality of IDEA, the section fronted two strong arguments as the foundation of their case. In their first argument, the section proposed that the state of New Jersey had accepted the federal IDEA funds that were meant to meet the cost of educating students with disabilities consequently agreeing to act in accordance with the IDEA by relinquishing its sovereign immunity. In the second argument, the section contended that following the enactment of the Fourteenth Amendment, Congress had in fact genuinely repealed the state sovereign immunity, which the New Jersey was still claiming to have in its argument for a dismissal motion. In accordance with the Rules 12(b) (1) and (b)(6), of the Federal Rules of Civil Procedure, the NJDOE and the State officials filed a motion of dismissal of the complaint by arguing that they were immune to the suit under the provisions of the Eleventh Amendment. They also held that the plaintiff’s complaint should be dismissed for failure to exhaust administrative remedies and that given the state’s sovereign immunity, it was wrong for an injunctive relief to be entered against it, particularly because it was not the right subject of an order for the provision of free and appropriate public

Curriculum Development Paper - Essay Example To wash hands is the best strategy to prevent the spread of germs in the healthcare environment. The hospitals are full of germs (disease causing micro organisms) and nurses have some power of ensuring that their spread is prevented. In order to impact this knowledge to the nurses, a lesson plan will be designed to guide the process of refreshing the knowledge on why washing hands is extremely significant in the healthcare environment, Hand washing Liaison Group (1999) About 20 nurses washing their hands will spend only five minutes when this is done at fifteen seconds each and if this is done throughout the day, a lot of time will be spent but it would be worth it as germs will be reduced considerably and the spread will also be limited. The nurses will have to wash their hands in warm water by using the hospital soap dispenser and leally lather it up. The nurses will wash the front as well as the back of their hands and they will pretend that they are going to handle a very delicate situation like surgery. The soap should be massaged between the fingers ensuring that the nails are properly washed and this should take about fifteen seconds per individual. The nurses can be timed (Bergquist & Pogosian 2000). The scrubbing action is very important as it helps to break up germs and remove them altogether. After this, hands should be properly rinsed with clean water and dried with a clean piece of cloth preferably clean white towel or the fresh paper towels currently in use. Nurses should note that when cleaning hands in the washrooms used by many people, the paper towel is the one to be used to open the door knobs and handles as they are in most cases contaminated. Since nurses are professionals in the medical field, they are in a better position to explain how the germs spread disease and due to this; the hand washing habit should be habitual and needing less prompting (Hoffman & Wilson 1994). Nurses have a responsibility of their own health and that of the patients as well because they are the ones offering professional assistance in this case. Learning the Importance of Hand Washing In order to ensure that nurses are updated on the correct procedure of washing hands, they will have to discuss why hand washing is important citing possible consequences of not doing so. On the other hand a list of benefits of washing hands will be established. There are lots of micro-organisms that cause diseases yet many of these cannot be seen by a necked eye. Precaution is therefore very important since the hospital also present an environment that could host even more germs than a normal home or house (Rosenau et al 2009). Objectives Nurses will have to concrete reasons as to why they have to wash their hands Nurses will also be required to explain and comprehend that

It is therefore a particularly difficult decision to make but then a decision must be reached and one that serves the best interests of the business. It must be just and sufficient considering employment and labour laws. Gordo has been tolerated for a very long time and for this reason his behaviour has continued to determinate up the current level where he appears not to uphold company values any more. Considering the company’s PCP, Gordo’s unpleasant behaviour has already been discussed verbally in his presence and a written warning issued but he did not show any significant effort to turn things around. He appeared to continue with a careless attitude and would always give reasons for his financial underperformance hence a probation was necessary. Probation would also serve as a good notice to him that the company is concerned with his performance and therefore requires of him to improve or face dismissal. The situation got worse with the latest discovery touching on lack of professionalism. He has lost two important accounts; this has significant implications to the market share, business and growth and financial performance of the company. There have also been cases of customer complains on his conduct. He fails to respond to customer calls and more importantly a physician complained that he had attempted to convert what was company business to his personal business.

UK Childrenswear Sector Essay Example | Topics and Well Written Essays - 1500 words

UK Childrenswear Sector - Essay Example According to the statistics, the value sector in 2006 accounted for 35.9% of all UK childrenswear sales, whereas the total clothing market accounted for 23.6% and it is estimated that the growth can increase further. The slow growth rate of Childrenswear in UK can be attributed to the factors like, slower birthrate in UK and the rapid growth of the value market in childrenswear. In spite of the overall sector growth, only the value and low-price fashion retailers have exhibited a continuous growth. Of the nine leading childrenswear retailers in UK, only seven that have a value or low price fashion positioning have gained market share between 2002 and 2007. Under traditional mid market retailers group, the market leaders like Next and Debenhams have only gained the equal share in market. The UK childrenswear market can be considered as the clothing supplier sector for the children under the age of 15 years. This sector produces or promotes the categories like infant clothing, toddler clothing, kids wear- girls clothing boys clothing, sports clothing, night wear etc., The childrenswear have experienced a risen value of 13.1% from 2001 to 2005 worth of PS6.3bn. The price deflation in UK has also influenced the childrenswear market, due to the increasing number of supermarkets and value retailers. However, the retailers like ASDA, Primark, Tesco have concentrated much on childrenswear rather than other non food sales. During this period these giants have concentrated much on pricing which have created a pricing strategic war in the childrenswear sector. In order to sustain and make a competitive position in the market, many other retailers have to follow the leader strategy, by cutting down the prices. Also the recent raise in the UK birth rate have also contributed rise for the baby wear sales In the recent years the UK retail childrenswear market have become a value conscious market trying to observe value through out the supply chain. Also the market is trying to impress the customer through various innovative and technology oriented services like creating email lists etc., rather than regular promotions. The UK market has become more product and brand led allowing the retailers to keep their own labels and to establish their exclusive lines of sales. This has gained a marked success over the supermarkets and value retailers who tend to focus on non branded items. The trend of success led the market to concentrate on the pricing. The childrenswear market is driven by 3 types of consumers. 1. Parents, 2. Children, 3. Non Parents who want to gift. Parents always wants the best and stand out look for their kids, which can hinder the market share of the non innovative product suppliers. People began to look for 'latest and unique fashion' for their kids. Though the female population under-15 years age is smaller than the male, the Childrenswear market have experienced a growth for Girls wear than the boys wear. This difference can be attributed to the behavioural and attitudinal differences between consumer behaviour of male and female. Girls do maintain an extensive wardrobe and are also much fashion consciousness, and can make high purchase with the changing trends. The girls' wear market in the UK shows some characteristics when divided on the basis of age group: under-nines and above-nines. Under-nines can be classified and targeted for more traditional children's

Racism in South Africa Essay Example | Topics and Well Written Essays - 1250 words

Racism in South Africa - Essay Example In South Africa for instance, Apartheid, a racist system was introduced in the 1940s by the Nationalist Party (ICFTU, 1984). These comprised of a 4.5 million minority that ruled over 21.5 majority Blacks. They propelled the racist dominance through the establishment of untrammeled system of abnormal powers that affected every other aspect of life. Symbolically Apartheid was inclined towards separation, exploitation and domination of the Whites over the preconceived inferior Blacks. Apartheid defined individuals in any social setup by racial segregation and the formal designation of individuals basing on color. The oppression was however exercised in myriad ways: disenfranchising all, impoverishing most, relegating them to Bantu education and thus permanent economic inferiority, expelling millions from ancestral land, imprisoning hundreds of thousands, and killing many. The machinery of apartheid was supported by laws, which were passed by a sovereign parliament which had the power to pass any law it wished, however oppressive, the courts were powerless to challenge them except on narrow interpretation or administrative law grounds. In short, the legal system was doctored to suit the interest of racism. Race conceptualised as a constraining and external characteristic. According to Durkheim concept of social facts racism could be portrayed as a conditional external repressive system. Created by a minority of individuals in a society and racially imposed upon a majority of the society against their will. The evil that Jim Crow's system exercised upon the Afrikaans was subversive, barbaric and unwelcome and acted contrary to the free will. Practical constrains of racism are evident when segregation soared greater heights that determined of where people lived, whom they could marry, where their children went to school, what they were taught, whether they could be in a particular area (cities especially) without a pass, what swimming pool, library and restaurant they could use, and, of course, whether they could vote. Less formally, the situation was even worse: police brutality was legendary, civil rights in daily life virtually nonexistent, wage differentials immense, and women's household labor virtually domestic slavery (Marcuse, 1995). Consequently the fact that Apartheid was enforced in foreign languange implied that Africans had to be familiar with the same language in order to enhance their aggression and agitate for their basic human rights with one voice. The social fact of language certainly meant that it was difficult, to do otherwise. In broader aspect this could be seen as a constrain that limited the freedom of action to enhance a collective mass psychology to demand and to bring about changes. This constrain behavior imposed upon individuals against there will limited their inalienable rights to free will hence unable to make decisions. And also it was impossible to resist the dominant way of doing things because to change it would require widespread co-operation. This had detrimental effects upon their social well-being. How race has been used to maintain law & order in society. In South Africa ethnic or regional "intrawhite"
