DE.CM-02 The physical environment is monitored to find potentially adverse events
The physical environment is monitored to find potentially adverse events. Control from NIST Cybersecurity Framework 2.0 framework, domain: DE - Detect.
Source: NIST CSF 2.0, DE.CM-02. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST CSF 2.0 in the compliance library.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.
