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 partial match
prevents

PR.DS-01 encryption of data-at-rest can protect swapped pages but does not stop improper memory locking, addressing only one exposure facet of the weakness.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can discover unlocked sensitive buffers, but does not itself implement the locking mechanism.

A.8.24 Use of cryptography partial match
degrades

Cryptographic controls can reduce exposure of sensitive data even if it is paged, but do not directly enforce memory locking.

A.8.28 Secure coding partial match
prevents

Secure-coding standards can mandate use of locked-memory APIs, directly preventing the weakness.

A.8.12 Data leakage prevention none match
mitigates

DLP can detect leakage of sensitive data from swap, yet does not prevent the data from being written there.
