1. Computer and Internet Security By: Steven Siggers Instructor: Dr. Marko Puljic

2. Introduction I choose this project to discover how to protect computers from viruses and other threats that may harm computers. Explain my objectives for computer security. The background information will include information about all threats that affects computers.

3. My Objectives Explain the background information on the threats that cause security problems on the Internet. Explain why and how computer and internet security is so important to users. Discover how to keep computers safe from hacker’s, viruses, and all other threats. What has been done so far to ensure computer and internet security.

4. Background Info on Threat’s Threats include the issues that causes computer security problems. Examples of threats include computer hacker’s, viruses, worms, Trojan horse, and many other threats that will harm a computer. As of day, many of these threats can and will occur, so all user’s must be cautious at all times.

5. What is a Computer Hacker ? A Hacker is a programmer who breaks into computer systems in order to steal or change information as a form of cyber-terrorism. Case: In 1999 a 19 year old Russian hacker named Maxim broke into an e-commerce (Amazon.com) web site and stole 300,000 credit card numbers, demanding $100,000 from the site owners, and threatened to post all the credit card numbers on the Internet if he did not get the money.

6. What is a Computer Virus? A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the user. Case: In 1974, the Rabbit virus infected computers, as a result, it reduced the system’s performance just before the computers crashed. As of today there has been over 51 world known computer viruses that has affected millions of computers. Viruses can be avoided, and reinstalling a computer’s operating system is a known approach of removing viruses.
