Cracker: Causes problems, steals data, corrupts systems; limited resources; moderate risk taking; medium frequency of attack.
Insider: Financial gain or system disruption; knowledge of systems and passwords; moderate risk taking; low frequency of attack.
Industrial Spy: Capture trade secrets or gain a competitive advantage; well funded, well trained; minimal risk taking; low frequency of attack.
Cybercriminal: Financial gain; well funded, well trained; moderate risk taking; low frequency of attack.
Cyberterrorist: Destruction to key infrastructure components; not necessarily well funded nor well trained; very high risk taking; low frequency of attack.
