[edit] 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.

[edit] Theory

In theory, It assumes that abnormal behaviour and activity has a simple to define model. Its advantage is simplicity of adding known attacks to the model. Its disadvantage is its inability to recognize unknown attacks.
