1. Unauthorized Internet traffic coming in (from the Internet to your computer).
2. Unauthorized Information going out (from your Hard Drive to some one else Web Server), AKA software calling home.
3. Accidental leakage. Firewall left disable, computer left in DMZ etc.
Unauthorized Information going out is mainly a function of "spyware" and programs that are "calling home". Unfortunately, the amount of programs that are calling home is growing by the day.
