Mitigating Controls (NIST 800-53 r5) AI

Requires digital signature verification before component installation, directly stopping execution of code downloaded without integrity checks.

Requiring cryptographic protection mechanisms forces correct signature verification to be implemented for data protection.

Mandating integrity verification tools directly requires proper cryptographic signature checking to detect unauthorized changes.

Protecting session authenticity requires correct verification of cryptographic signatures or equivalent mechanisms.

ID.RA-09 full match
prevents

Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.

PR.DS-01 mostly match
prevents

Digital signatures are explicitly cited to protect integrity of data-at-rest, so proper verification directly mitigates the weakness.

PR.DS-02 mostly match
prevents

Digital signatures are explicitly cited to protect integrity of data-in-transit, so proper verification directly mitigates the weakness.

PR.PS-05 mostly match
prevents

Prevents execution of unauthorized software, blocking the outcome of an unchecked download.

PR.PS-06 partial match
prevents

Secure SDLC practices include code signing and signature verification requirements, addressing the weakness during development.

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.

prevents

Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.

prevents

Establishing approved cryptographic solutions and usage practices lowers the probability that signature-verification steps will be omitted or incorrectly implemented.

none

Requiring suppliers to disclose vulnerabilities and mandating verified updates lowers the chance that code lacking integrity checks will be deployed.
