Security monitoring. Level 1 (a to c): management of technical vulnerabilities; intrusion detection and/or prevention systems monitoring traffic; and current policies on network intrusion detection and prevention. Level 2 is the same; Level 3 adds regular technical compliance reviews that confirm systems stay secure as designed, with defined depth, scope, tools and methodology, and assessment of the reviewers' technical competence.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
