Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 directly requires validation of information inputs, which structurally prevents type-validation failures from being introduced or exploitable.

A.8.29 Security testing in development and acceptance mostly match

finds

Security testing can detect type-validation flaws but does not prevent them during development.

A.8.25 Secure development life cycle partial match

prevents

Secure development lifecycle mandates input validation and type checking to prevent improper type handling.

A.8.26 Application security requirements partial match

prevents

Application security requirements explicitly include validation of input data types and formats.

A.8.27 Secure system architecture and engineering principles partial match

prevents

Secure architecture principles promote defensive input handling and type enforcement at system boundaries.

A.8.28 Secure coding partial match

prevents

Secure coding standards directly require proper type validation of all external inputs.
