Misuse detection
Misuse detection actively works against potential insider threats to vulnerable company data.
==Misuse==
Misuse detection is an approach in detecting attacks. In misuse detection approach, we define abnormal system behaviour at first, and then define any other behaviour, as normal behaviour. It stands against anomaly detection approach which utilizes the reverse approach, defining normal system behaviour and defining any other behaviour as abnormal.
In other words, anything we don't know is normal. Using attack signatures in IDSes is an example of this approach.
Misuse detection has also been used to refer to all kinds of computer misuse.〔Helman, Paul, Liepins, Gunar, and Richards, Wynette, "Foundations of Intrusion Detection," The IEEE Computer Security Foundations Workshop V, 1992〕 See Intrusion detection.
