Stuxnet free essay sample

Future of Cyber War David Adams Legal and Ethical Issues in Computing CIS 4253 The discovery in June 2010 that a cyber worm dubbed ‘Stuxnet’ had struck the Iranian nuclear facility at Natanz suggested that, for cyber war, the future is now. Yet more important is the political and strategic context in which new cyber threats are emerging, and the effects the worm has generated in this respect. Perhaps most striking is the confluence between cyber crime and state action. States are capitalizing on technology whose development is driven by cyber crime, and perhaps outsourcing cyber attacks to non-attributable third parties, including criminal organizations. Cyber offers great potential for striking at enemies with less risk than using traditional military means. It is unclear how much the Stuxnet program cost, but it was almost certainly less than the cost of single fighter-bomber. Yet if damage from cyber attacks can be quickly repaired, careful strategic thought is required in comparing the cost and benefits of cyber versus traditional military attack. We will write a custom essay sample on Stuxnet or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page One important benefit of cyber attack may be its greater opportunity to achieve goals such as retarding the Iranian nuclear program without causing the loss of life or injury to innocent civilians that air strikes would seem more likely to inflict. Nevertheless, cyber attacks do carry a risk of collateral damage, with a risk of political blowback if the attacking parties are identified. Difficulty in identifying a cyber attacker presents multiple headaches for responding. A key strategic risk in cyber attack, finally, lies in potential escalatory responses. Strategies for using cyber weapons like Stuxnet need to take into account that adversaries may attempt to turn them back against us. The discovery in June 2010 that a cyber worm dubbed ‘Stuxnet’ had struck the Iranian nuclear facility at Natanz suggested that, for cyber war, the future is now. Stuxnet has apparently infected over 60,000 computers, more than half of them in Iran; other countries affected include India, Indonesia, China, Azerbaijan, South Korea, Malaysia, the United States, the United Kingdom, Australia, Finland and Germany. The virus continues to spread and infect computer systems via the Internet, although its power to do damage is now limited by the availability of effective antidotes, and a built-in expiration date of 24 June 2012. (McMillan, 2010) Stuxnet is a sophisticated computer program designed to penetrate and establish control over remote systems in a quasi-autonomous fashion. It represents a new generation of ‘fire-and-forget’ malware that can be aimed in cyberspace against selected targets. Those that Stuxnet targeted were ‘air gapped’; in other words, they were not connected to the public Internet and penetration required the use of intermediary devices such as USB sticks to gain access and establish control. Using four ‘zero-day vulnerabilities’ (vulnerabilities previously unknown, so that there has been no time to develop and distribute patches), the Stuxnet worm employs Siemens default passwords to access Windows operating systems that run the WinCC and PCS 7 programs. These are programmable logic controller (PLC) programs that manage industrial plants. The genius of the worm is that it can strike and reprogram a computer target. (Garza, 2010) Some media reports mistakenly thought the Iranian light-water power reactor at Bushehr was also a target. Iran confirmed that Stuxnet infected personal computers there while denying that much damage was inflicted. (Yong, 2010) But Bushehr seems an unlikely target, because the plutonium produced by such light-water reactors is not well suited for weapons purposes. The more likely target is Irans uranium-enrichment program. Although most of the 4,000–5,000 centrifuges operating to date at the pilot and industrial-scale fuel-enrichment facilities at Natanz have been producing only low-enriched uranium, the same centrifuges could be put to use to produce highly enriched uranium for weapons. Alternatively, and in a more likely scenario, it is feared that Iran could be operating secret centrifuge facilities to produce highly enriched uranium. The key to the Stuxnet worm is that it can attack both known and unknown centrifuges. Although there is no hard evidence that Stuxnet has exposed Ahmadinejad to public criticism that the government failed to competently defend key installations, cyber can nevertheless be a tool to discredit, destabilize and weaken the authority of adversarial regimes. Cyber also offers great potential for striking at enemies with less risk than using traditional military means. For example, North Korea poses threats other than through its nuclear program. It is involved, for example, in extensive counterfeiting. Cyber attack offers potential options that may prove effective in countering such criminal activity. Cyber is, moreover, less costly than traditional military action. It is unclear how much the Stuxnet program cost, but it was almost certainly less than the cost of single fighter-bomber. Third parties currently working in concert with a state may or may not be held under tight control. Criminal groups are mercenary. They may well sell their services twice. Outsourcing to the underworld is a slippery slope.

An Overview of the Motorcycles History

An Overview of the Motorcycles History Like many inventions, the motorcycle  evolved in gradual stages, without a single inventor who can lay sole claim to being the inventor. Early versions of the motorcycle were introduced by numerous inventors, mostly in Europe,  in the 19th century. Steam-Powered Bicycles American Sylvester Howard Roper (1823-1896) invented a two-cylinder, steam-powered velocipede in 1867. A velocipede is an early form of a bicycle in which the pedals are attached to the front wheel. Ropers invention can be considered the first motorcycle if you allow your definition of a motorcycle to include a coal-fired steam engine. Roper, who also invented the steam-engine car, was killed in 1896 while riding his steam velocipede.   Around the same time that Roper introduced his steam-powered velocipede, Frenchman Ernest Michaux attached a steam engine to a velocipede invented by his father, blacksmith Pierre Michaux. His version was fired by alcohol and twin belt drives that powered the front wheel.   A few years later, in 1881, an inventor named Lucius Copeland of Phoenix, Arizona developed a smaller steam boiler that could drive the rear wheel of a bicycle at the amazing speed of 12 mph. In 1887, Copeland formed a manufacturing company  to produce the first so-called Moto-Cycle, though it was actually a three-wheeled contraption.   The First Gas-Engined Motorcycle Over the next 10 years, dozens of different designs for self-propelled bicycles appeared, but its widely acknowledged that the first to use a gasoline-powered internal combustion engine was the creation of German Gottlieb Daimler and his partner Wilhelm Maybach, who developed the Petroleum Reitwagon in 1885. This marked  the moment in history when the dual development of a viable gas-powered engine and the modern bicycle collided. Gottlieb Daimler used a new engine invented by engineer  Nicolaus Otto. Otto had invented the first Four-Stroke Internal-Combustion Engine in 1876, dubbing it the Otto Cycle Engine As soon as he completed his engine, Daimler (a former Otto employee) built it into a motorcycle. Oddly,  Daimlers Reitwagon did not have a maneuverable front wheel, but instead relied on a pair of outrigger wheels, similar to training wheels, to keep the bike upright during turns.   Daimler was a prodigious innovator and went on to experiment with gasoline motors for boats, and he also became a pioneer in the commercial car manufacturing arena. The company bearing his name eventually became Daimler Benz- the company  that evolved in the corporation we now know as Mercedes-Benz. Continued Development From the late 1880s onward, dozens of additional companies sprang up to produce self-propelled bicycles, first in Germany and Britain but quickly spreading to the U.S.   In 1894, the German company,  Hildebrand Wolfmà ¼ller, became the first to establish a production line factory to manufacture the vehicles, which now for the first time were called motorcycles.  In the U.S., the first production motorcycle was built by the factory of Charles Metz, in Waltham, Massachusetts.   The Harley Davidson Motorcycle No discussion of the history of motorcycles can end without some mention of the most famous U.S. manufacturer, Harley Davidson.   Many of the 19th-century inventors who worked on early motorcycles often moved on to other inventions. Daimler and Roper, for example, both went on to develop automobiles and other vehicles. However, some  inventors,  including William Harley and the Davidsons brothers, continued to exclusively develop motorcycles. Among their business competitors were other new start-up companies, such as Excelsior, Indian, Pierce, Merkel, Schickel, and Thor. In 1903, William Harley and his friends Arthur and Walter Davidson launched the Harley-Davidson Motor Company. The bike had a quality engine, so it could prove itself in races, even though the company initially planned to manufacture and market it as a transport vehicle. Merchant C. H. Lange  sold the first officially distributed Harley-Davidson in Chicago.

Bussiness Plan for Start-up Restaurant Dissertation

Bussiness Plan for Start-up Restaurant - Dissertation Example This dissertation demonstrates a business plan, that is designed for a restaurant named ChopChop, that deals in organic food items such as salads and health juices in Doha, Qatar. As per the market analysis performed, it was observed that majority population of Qatar is expatriates that increase the scope for continental food flavors among the target customers. A primary analysis performed among the target market customers showed tendency towards consuming healthy food in comparison to fast-food items. Price is not a major issue for the customers of the selected region. The services of Chopchop will be designed in an individual manner wherein the customers can select the ingredients to be put in their salads from a large variety of vegetables in the store. Also, wraps can be served along with the salads with meat, beef and shrimp. The strategic aim of ChopChop is to capture the target market with a differentiation focus. The pricing of the products will be designed with price skimmin g strategy for increasing product life in market. The finical calculations showed that ChopChop can achieve its break-even point by the end of 7 months of its initiation. It has been recommended that the online activities such as website development should be minimized during the first year and replaced with the provision of launching ChopChop with two stores. In conclusion, the researcher recommends a possible future strategy for the company, that will be mostly focused towards identification and penetration of other potential Middle Eastern markets.

Viewer Identification with Television Characters Essay

Viewer Identification with Television Characters - Essay Example The reason I identified with his character before was because of his boyish charm that made him irresistible to all women, except Kate Beckett who seems to be immune to his charms. If I ever become a millionaire, I would want to be the gentleman millionaire that he is. He treats the women right and in exchange, the women treat him like a god as well. Just like Richard Castle, I too am a very loyal friend who is always there when any of them need my help. We are similar in the way that we treat our friends, more like family than some strangers whom I just met and have to find something in common with. We both exude this sense of familiarity that makes it easy for other people to get along with us even though we just met them. That is not hard to understand. After all, we both tend to bend over backwards for people just to make sure that we are liked. Castle was raised by a single mother just as I was. We both respect and and love our mothers to the extent that we would give our respective mothers the shirts off our backs if she asked us to. That is the kind of gratitude that Richard Castle displays for his mother. Even though he sometimes acts like he is just putting up with his mothers presence (name any man who does not pretend that at one time or another with his mom), the reality of their situation is that he loves her deeply and would never want to see her hurt in any way by any person. We all know that men are constantly looking for their partner in life. Sometimes, men get married because they have found the one for them. That is what Richard Castle did at one point in his life. The result was a an intelligent daughter named Alexis who was left in his custody after he divorced his first wife. His relationship with Alexis is the kind that I would want to have with any son or daughter of mine should I ever get married and find myself divorced, or even if I dont end up divorced. As for his loyalty to women, I

Gerontology - Essay Example The authors include, Dan Buettner, Sally Beare and Howard S. Friedman. They have applied both different and similar ideologies in their work. Based on health, the authors have different views on the fitness of the individuals in the blue zones. However, they have a common understanding where they believe that health depends on individual body fitness and genetic structures. Sally has done her research on the in habitats on the island by the name Okinawa, located in Eastern China (Beare 2006). She compares and contrasts the health her research samples with those from the Western countries. The island holds a record of the longest living persons in earth. She starts by comparing their physical attributes with those of the Western in habitats. Her results show that signs of healthy lifestyles before she gets into deeper research about the diseases found in the island (Beare 2006). Unlike the West where stroke, heart attacks and cancer related deaths are common, her area of study has less than 20% cases. Most diseases are so rare among the populations raising questions on the causes of the increased health cases. Scientists involved in the research have come up with results that show the strong immune systems found in the old generations. Sally related their strength to those of the young generations where that are able to fight most deadly diseases. Dan, on the other hand, has carried out most of his researches in Central and South America in some of the indigenous communities. However, his focus is on other attributes that contribute to long living other than health (Buettner 2007). For example, his study on Costa Rica reveals the physical lifestyles where his focal point is social ways of life such as how they cook their food and diet compositions (Buettner 2007). With his knowledge from other blue zones, she has come up with different myths that are common in people from other countries such as the U.S. The cultures use

Violence in the School Systems Essay -- Violence Education Crime Essay

Violence within this country has been an ongoing problem throughout history. Due to all the media coverage of more recent violent events in school history, such as Columbine, it is of popular belief that violence in school systems is the worst it has ever been. There are many questions about what type of violence occurs most often, what gender and what ethnicity violence is most affecting in schools. Violence can be defined by any deliberate act, serving no legitimate purpose, which causes injury or which could reasonably be expected to cause injury to another person. To be considered reportable, the conduct should be either intentional or reckless in nature. (Basic Education Circular on Safe Schools, 1996) School violence can also be defined as any school related activity that produces a victim. The first table was a chart that was drawn up in conclusion to a survey that was conducted in 1999. It was asking children in grades 9-12 different question about feeling threatened and carrying or seeing weapons in school. The chart was broken down into different grades, along with various ethnicities, and gender. (www.nces.ed.gov/crime2001/tables) Out of all the questions asked in the survey, the highest positive response to a question of illegal drugs on school property. An average of 30.2% of the children responded that they had been offered, sold or given illegal drugs at school. Leading the category was Hispanic males with 36.9% of them having engaged in some form of drug distribution or some one offering them drugs. The next question with a high response was if these children have ever engaged in a physical fight on school property. A total of 14.2% answered yes to the question. In the same category Hispanic ... ... help the students set goals and come to appreciate the relationship between responsible good behavior and achieving goals. In this program they will earn privileges for good attendance, work accomplishments and goal achievements. This program will be evaluated to determine if similar programs are to be set up in the future throughout the state. (www.msde.state.md.us/juvenilejustice alt.html) Although violence in the United States is a problem that needs a lot of attention, the amount of episodes is and hopefully will remain declining over the years. Teachers, parents and peers all have an impact on each and every child that goes through school systems. As long as they keep teaching violence prevention programs, the numbers will keep dropping. Although this problem will never fully go away, the percentage of violence in schools will be constantly dropping.
