Sri Harsha Maddineni Z1725592 CSCI 630-3 Security Enhancements in IEEE 802.11 Wireless LANs through Wired Equivalent Privacy protocol Introduction: Wireless networks are less secure when compared to wired networks. Wired networks such as Ethernet are physically connected, where as in wireless networks are connected through wireless radio waves without physical connection between them. As a result, a security breach is easier in wireless networks when compared to wired networks. In the current world, electronic gadgets like cell phones, ipads and laptops are interconnected with other devices. In wireless device, a network radio receiver is able to hear the conversations on a wireless channel as per its range. Therefore it is easier to breach the conversations that are occurring in wireless networks. The data that is transferred on the internet should be reliable and secure because it might contain personal data information like bank login details or insurance details etc. To prevent the issues that are happening over the network, there are different algorithms used in day to day life by software engineers while designing the netw ork. Among them Wired Equivalent privacy algorithm is most important one. The main purpose of this algorithm is to produce integrity, reliability and security to data that is transferred on a wireless network. The thesis that I am writing is used for software engineers who are interested in implementing WEP protocol for their network designs andShow MoreRelatedWireless Security3835 Words   |  16 PagesWireless Network Security Jon P.

This is largely due to the increase in the value of a network as more users are attached to it. The value added to a network by nature of connecting more devices to it, is summarized in Metcalfs law. Metcalfs law states that if you connect any number, n, of machines - whether computers, phones or even cars - and you get n squared potential value.[1] The incredible growth of the Internet seems to validate Metcalfs law.

Bus 401 Mod 3 Case - 1108 Words

TUI University BUS 401 Case Study Module 3 Dr. Yi Ling Abstract Outsourcing occurs when a company either buys products or services from outside sources or sends work to outside contractors versus doing it themselves. There are several advantages and disadvantages to outsourcing to include cost savings, sharing risk and developing better leaders internally. There are also some disadvantages like lack of quality control, loss of some management functions and losing the ability to build well rounded leaders in all aspects of the company. In a country like Iraq, the United States military is outsourcing many occupations in an effort to rebuild the Iraqi economy and eliminate the need for military presence at the same time†¦show more content†¦The second advantage is the shared risks associated with outsourcing. If there are five different companies each producing one piece of an object or item to make a whole item, if something happens to one of the firms like filing for bankruptcy, the entire operation doesn’t suffer, only that o ne piece of the whole product. An example is a financial profile. I have in the Army what is called the Thrift Savings Program, like a civilian 401k. There are five different investment options and I elected to put 30% of my contributions into one fund, 30% in another, and then 40% in yet another. If one of those funds start going south, it is my hope that the other two compensate the first one. The third advantage is being able to outsource work when the need for production rises. Instead of having to hire additional employees to augment the increase in labor, a company will have a set staff and then when the need arises, they will hire out for the additional work to be completed. The fourth advantage to outsourcing is that it can help develop internal staff. As I stated in the advantage above, outsourcing projects help meet performance peaks, but it can also assist in completing projects that are nearing the end of its requirements. What this does is allow the company staff to focus on new initiatives thatShow MoreRelatedComputer Networking: a Top-Down Approach Featuring the Internet, 4th Edition - Solutions to Review Questions and Problems27823 Words   |  112 Pagespolitely cancel the engagement if they have reasonable excuses. 3.

Persuasive Article - Bowling for Columbine - Michael Moore free essay sample

By Emily Wanklyn Film maker, author and political activist, Michael Moore, created controversy in 2002 with his American documentary â€Å"Bowling for Columbine†. The documentary explores the Columbine school shooting, gun laws, and why Americans are so obsessed with violence and fear. Moore cleverly uses a variety of cinematic techniques to manipulate his audience. For instance, editing, music amp; sound, use of archival footage, and political agenda/bias. One of the cinematic techniques that Moore uses that is most affective in his documentary is editing. For example; Charlton Heston’s speech. Charlton Heston, being the president of the National Rifle Association (NRA), was an easy target to blame for America’s astronomical amount of people that are killed by firearms. Moore uses two of Charlton’s speeches by strategically cutting bits and pieces from each to create a speech that was never even spoken. â€Å"I have only five words for you: ‘from my cold dead hands’ † -Charlton Heston ‘Cold dead hands’ was nowhere in the speech and was actually given a year later in Charlotte, N. We will write a custom essay sample on Persuasive Article Bowling for Columbine Michael Moore or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page C. In doing this, Moore tactically put this footage in after showing the weeping children outside Columbine school. This made it seem that Charlton Heston and his team  rushed to Littleton to hold gun rallies and demonstrations  directly after the tragedy, portraying to the audience that Heston and the NRA are arrogant, insensitive and selfish. In the beginning of the film Michael Moore goes to a bank in the USA, and opens an account to receive a gun. However, through the use of editing this is not the case. In Michael Wilson’s film, ‘Michael Moore hates America’ , Wilson interviews the woman working at the bank and she corrects the situation in saying that in fact it took Michael Moore over 30 days to receive the gun. Moore left out the important factors of the process and made it out that it took only one day. In his efforts, Moore did this to create an idea in the audiences judgements that the gun laws in the USA are not strict and that owning a gun requires no attention. Music and sound was another manipulated technique that Moore used to persuade the audience. During the film Moore included his dry sense of humour and played the song ‘what a wonderful world’ (By Louis Armstrong) when it cut to the montage of violent war scenes and American foreign policy decisions throughout the 20th and 21st century. This perceives the US government as being at fault for the increase of violence in young adolescents. Punk rock music, Marilyn Manson, violent video games and action movies were also put to blame in the documentary. As well as blaming the government, this music and scene choice is clearly a mockery of the government. Archival footage was used to strongly persuade the audience as the use of it between the scenes which are inconsistent, makes the audience think that those inconsistencies are true. strongly persuaded the audience In doing so, this positions the audience to feel distressed, sympathetic, scared and alarmed. Near the halfway point of the film, a series of clips depicting â€Å"alarming† advice and information from the media is put together. In the background, a heart can be heard beating. As the clips continue, the heart   beat increases. This further enhances the actual anxiety the viewer experiences while watching these clips. influence -Misleads you Master of illusion Body Paragraphs: * Editing * What does the editing in that part do to the audience? * Getting the bank to give him a gun straight away, not true- took him a few days * Use of archival footage * Play sirens and distressed 911 callers * Actual phone call playacks that happened during the 911 attack and school shooting * Footage of people running and screaming,yelling, crying, freaking out * * Making the audience to feel distressed, scared, sympathetic, alarmed, Manipulated of cinematic techniques Guns don’t kill crowds of innocent people; maniacs with easy access to military-grade weapons do Maybe Im a dreamer, but I wish mental health care was as easy to get as, say, a gun. -Andy Borowitz
