Computer Defining denial of service, worm, virus and hoax. Examples of negligence or incompetence that leads to crime. CI R M E By: Megan Price

Computer Crime Overview General Facts about Computer Crime Denial of Service Information relating to Worm and Virus Causes of Computer Crime What is an hoax? Questions/ Comments References

General Information What is computer crime? 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

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

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

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

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

Hoax Intentional messages warning about false viruses and suggestions to remove a file or send the false warning to those in your address book Warning signs against a hoax: Look for phrases like “forward this to everyone you know” and “this is not a hoax” Uppercase letters and exclamation points are warning signs Check references related to the information to verify it is factual and true Hoax is often in the form of a chain letter

Protection for Computers Viruses= Anti Virus Protection Anti virus software: program that searches hard drive and floppy disk for potential viruses. If a virus is present the software will clean and delete necessary files Worm =Firewall Firewall is often a program that will not allow any unauthorized computers to get acess to protected computers. Important to protect networks from Internet hackers.
