Any crime in which the computer is the primary factor Examples include : -Unauthorized Use -Forgery & Counterfeiting -Fraud & Larceny -Harassment or stalking in cyberspace -Stealing Information by obtaining the hard drive or laptop -Inappropriate use of Internet services

  4. Denial of Service • An Incident in which a user or organization is deprived of the services of a resource they would normally have and need • Destroy programming & files in a system • Does not usually result in theft information or security loss • Usually intentional and malicious but can happen accidentally

  5. DoS Examples • Commonly, a DoS attack happens when more traffic is sent to a network address than the programmers planned (basically too much information for system to handle) • Sending oversized ICMP packets • SYN Attack, Teardrop Attack, Smurf Attack, Viruses

  6. Computer Virus A program or code that is loaded onto your computer without your knowledge. Facts about Viruses: - all viruses are manmade and are spread by human action - simple viruses are dangerous because they use up memory and bring system to a halt - more complex viruses can transmit across networks and bypass security systems - commonly spread by sharing infecting files and sending viruses as attachments in email

  7. Virus vs. Worm Worm- subclass of a virus and similar by design Difference is its capability to travel within the computer without outside help of a person. Has the capability to replicate itself on the computer Example: worm replicates and send itself out to everyone in receiver's address book and continues in the same manner
