Mitigating Controls (NIST 800-53 r5) AI

Least privilege limits the damage an injected code fragment can perform once executed.

Developer testing and evaluation finds code paths that accept and execute externally influenced strings.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

Input validation directly stops untrusted data from being used to construct executable code without neutralization.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
prevents

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

prevents

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
