What else in your programme already covers this

This control maps to 41 controls across 20 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.

You are reading one control. How much of CMMC 2.0 have you already done?

CMMC 2.0 CM.L2-3.4.7 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of CMMC 2.0 your existing evidence covers. Hold FedRAMP Moderate and 108 of 110 CMMC 2.0 controls already carry evidence.

If you hold FedRAMP Moderate98.2% covered · 2 gaps If you hold NIST SP 800-171 Rev 394.5% covered · 6 gaps If you hold NIST SP 800-53 Rev 585.5% covered · 16 gaps If you hold ISO 27001:202279.1% covered · 23 gaps If you hold ISO 27002:202267.3% covered · 36 gaps If you hold CIS Controls v864.5% covered · 39 gaps

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. 1 were rejected on the FedRAMP Moderate pair alone.
