Abstract
A method of describing intrusion signatures, which are used by an intrusion detection system to detect attacks on a local network. The signatures are described using a “high level” syntax having features in common with regular expression and logical expression methodology. These high level signatures may then be compiled, or otherwise analyzed, to provide a process executable by a sensor or other processor-based signature detector.
