intrusion detection parameter

This phrase is compositional rather than a term of art. "Parameter" retains its ordinary technical meaning (a configurable value, measurable feature, or boundary condition) and is simply modified by "intrusion detection" to indicate its domain of application; sources use it to describe values against which monitored events are compared to determine whether an intrusion event has occurred, where such parameters define which activity corresponds to unusual or intrusive behavior. Across patents and research literature the phrase shifts freely — referring variously to network features extracted from traffic datasets for detecting intrusions, to machine-learning weights acquired and updated by a detection system, and to configuration inputs such as maximum numbers of systems to install or cost ceilings. No authoritative standards body (NIST, ISO, AICPA, CIS, or any regulator) defines "intrusion detection parameter" as a standalone term with a fixed meaning distinguishable from its component words.

Advisory only. A term this product ships is defined by an authority document, not by a search result.
