CMMC 2.0 AC.L2-3.1.22: Control Public Information

Control CUI that is posted to or processed on publicly accessible systems so CUI is not released to the public.

What else in your programme already covers this

This control maps to 36 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.

Other controls in Access Control

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

CMMC 2.0 AC.L2-3.1.22 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.

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.
