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.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 full match
prevents

Encryption and cryptographic controls for data-at-rest directly prevent cleartext storage of sensitive information.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography full match
prevents

Cryptography control directly mandates encryption of sensitive data at rest.

A.5.12 Classification of information partial match
prevents

Classification identifies sensitive data that must not be stored in cleartext.

A.5.14 Information transfer partial match
degrades

Transfer policies can require encryption, indirectly reducing cleartext storage risk.

A.7.14 Secure disposal or re-use of equipment partial match
mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

A.7.9 Security of assets off-premises partial match
mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

A.8.10 Information deletion partial match
mitigates

Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.
