Other controls in SC - System and Communications Protection

You are reading one control. How much of FedRAMP Moderate have you already done?

FedRAMP Moderate SC-45(1) is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of FedRAMP Moderate your existing evidence covers. Hold ISO 27002:2022 and 182 of 323 FedRAMP Moderate 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. 348 were rejected on the ISO 27002:2022 pair alone.
