Mitigating Controls (NIST 800-53 r5) AI

SC-28 Protection of Information at Rest good match

SC-28 requires cryptographic or equivalent protection of sensitive data at rest, directly stopping cleartext storage in accessible resources.

When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.
