cybercrime Crime committed using a computer.
threat The estimated severity of a security breach. For example, the risk of having all customer credit card numbers stolen is a severe threat.
vulnerability The likelihood of a security breach of systems or data occurring. For example, if the likelihood of a hacker stealing all the user passwords on a system is very low, the system is not very vulnerable to that risk.

cracker A hacker with malicious or criminal intent.
cyberwar Groups of international hackers attacking sites in the countries where the rival hackers live.
