Background: Security

  • System security affects each person who has a networked computer. Whether on an isolated private network or connected to the Internet, the possibility exists for unauthorized users to break in to a machine or cause the machine to become unusable through a denial of service attack. They may also use the network to perform insertion (also known as man in the middle) attacks.
  • Even home computer users must, in this day and age, protect themselves by securing their systems.
