Requires monitoring of the system to detect attacks and attack indicators against defined monitoring objectives, and to detect connections that were not authorized whether local, networked or remote, with unauthorized use identified by defined techniques, monitoring capability placed strategically and at ad hoc points, the monitoring itself protected from tampering, activity heightened on credible threat information, legal review obtained where required, and findings issued to defined personnel at a defined frequency.
NIST SP 800-53 Rev 5 NIST800-SI-4 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of NIST SP 800-53 Rev 5 your existing evidence covers. Hold ISO 27001:2022 and 163 of 300 NIST SP 800-53 Rev 5 controls already carry evidence.
Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 342 were rejected on the ISO 27001:2022 pair alone.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
