intrusion detection and prevention mechanism

** This phrase is compositional rather than a term of art. The field standardizes on the established label *intrusion detection and prevention system (IDPS)* — software that automates the process of monitoring events in a computer system or network, analyzing them for signs of possible incidents, and attempting to stop detected possible incidents — while "mechanism" functions only as a generic structural substitute for "system," carrying no distinct meaning of its own. IDPS technologies are focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators. Substituting "mechanism" for "system" in this phrase does not create a separate concept; it merely describes the same class of capability at a more abstract level. **VERDICT:** COMPOSITIONAL --- **Sources:** - NIST CSRC Glossary, *Intrusion Detection and Prevention System (IDPS)*: [csrc.nist.gov/glossary/term/intrusion_detection_and_prevention_system](https://csrc.nist.gov/glossary/term/intrusion_detection_and_prevention_system) — sourced from NIST SP 800-137. - NIST SP 800-94 Rev. 1 (Draft), *Guide to Intrusion Detection and Prevention Systems (ID
