Mitigating Controls (NIST 800-53 r5) AI

SA-22 directly requires replacing components once vendor support ends, structurally preventing reliance on unmaintained third-party code.

GV.RM-04 partial match
prevents

GV.RM-04's high-level risk-response criteria can indirectly discourage unmaintained third-party use via policy, but alone removes none of the concrete supply-chain or maintenance decisions that produce CWE-1104.

finds

A maintained asset inventory plus scheduled scanning and patching directly reduces the window during which known vulnerable third-party components remain exploitable.

prevents

Periodic validation, certification demands, and life-cycle monitoring of supplier components help surface and replace unmaintained third-party elements before they become exploitable liabilities.

mitigates

Regular exposure to external advisories and vulnerability disclosures helps teams identify and replace unmaintained third-party components before attackers can exploit known weaknesses in them.
