Identify the main stakeholders to the IT system. The main stakeholders to the IT system are company and government who uses secuID 3. Describe one ITGS social/ethical concern in the article. The Data Breach in this article refers to their security system data being violated by an outside offender, such as it being stolen or copied when it's not supposed to be. The advanced cryptographic system is the security system that has an extra layer of security by an electronic token authenticator that generates a time-based number for the users to input while logging in with their password. It is suspected that the master key for the encryption algorithm was stolen, which is the huge secret number that is part of the system. 4. Describe ITGS terminology and systems. SecurID- a mechanism developed by RSA Security for performing two-factor authentication for a user to a network resource 5. If possible, describe a solution to the concern (issue). The solution for this issue is to update the security system often and try to get against from hackers. Having SecurID make up a new algorithm to be used for the system could reinforce the system's security again, if it's possible to make up a new algorithm. Other than that, SecurID would probably have to make up a whole new security system since their current stolen algorithm is probably going to be published and recopied, and the system not secure anymore.

Explain how Google's algorithm works. Why is it hard to rank high? all nov 9 johny

The Google algorithm is also called as page ranking. Page Rank depends on the outstandingly democratic nature of the web via to enormous link structure as the sign of the values for each individual page. Google would understand a page A to page B as vote; it would look noticeably more at links age receiver and the sheer volume of votes. It would analyze what you are searching for and it would pick pages the most important page from the rest of the file that is relevant to your topic. Sometimes important pages wont answer you question. That's why Google page rank is combined with complicated text matching techniques to find the page that is important and similar to your question. Google does more then searching pages that has a match to your question it would examine the feature of the page content (satisfied) and that it would decide that is this page is a good match of your question. Because many websites don't have the possibilities to get highly ranked, because they also need to compete with other websites that comes from the company and they got millions of back links. For example you want to make a website about selling second hand stuff. When your going to try to search about second hand stuff it would directly show you E-Bay because it more popular and it has more views. The websites that you may been searching for must be on the 15 page or more then that because the web may have not enough back links or even none.

1. Identify the area of impact the scenario relates to. Business 2. Identify all ITGS terminology and phrases (IT and social/ethical). Botnets, worm, malware, 3. Describe one ITGS social/ethical concern in the article. Security is the main issue in this article since it is dealing with worms, which infects and damage computer files. 4. Describe the relationship of the main stakeholders to the IT system. The main stakeholder, Facebook, is combating Koobface worm, which is, a malware (malicious software) to prevent it from infecting its users PC. 5. Explain the relationship between the IT system and the social/ethical issue identified in question 3. Koobface worm is a malware that could infect Facebook's users' computer, which is a security issue. It is estimated that the group earned more than $2 million from June 2009 to June 2010 by delivering the victims of its worm to unscrupulous marketers and makers of fake antivirus software. 6. Discuss at least one problem that relates to the impacts of the social/ethical issue. A Koobface attack starts with an invitation to watch a video and a message about updating the computer's Flash software. Clicking to get the update begins the download of Koobface, which gives criminals control of the computer, while the worm tries to spread itself further through the victim's social network contacts. This is a security breach to Facebook's users computer. When the criminals have control of the computer, they can do anything they want with it like, stealing personal information, etc. 7. Evaluate one solution that addresses the problem identified. Facebook need to step up their security for their users safety. To halt Koobface, Facebook uses algorithms that can detect suspicious posts and hijacked accounts, looking for unusual behavior like log-ins from odd places and a surge in messages sent. Facebook also keeps a blacklist of malicious Web links to prevent them from being shared on the site. When Koobface posts find a
