Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of inputs to block the eval-style injection (CWE-95) that enables unauthorized data access.

prevent

Enforces access-control decisions so that even a successful injection cannot read sensitive user data outside the app's authorized scope.

prevent

Limits the privileges granted to apps, reducing the impact of any injection that bypasses input validation.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and avoidance of unsafe dynamic evaluation.

detects

Security testing in development can detect eval injection vulnerabilities before deployment.

prevents

Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.

prevents

Application security requirements include rules against dynamic code execution of untrusted input.

prevents

Secure architecture principles discourage unsafe dynamic evaluation constructs.

prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

none

Separation of environments limits the blast radius if eval injection occurs in non-production.
