Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation explicitly checks that supplied data matches expected types and rejects mismatches before they reach processing logic.

finds

Security testing can detect type-handling flaws but does not itself implement the preventive control.

prevents

Secure development lifecycle includes input validation and type checking that directly mitigates improper handling of unexpected data types.

prevents

Application security requirements typically mandate strong input validation and type enforcement to prevent malformed data processing.

prevents

Secure system architecture principles encourage robust input handling but do not specifically address data-type validation.

prevents

Secure coding standards explicitly require type checking and input sanitization, directly addressing improper handling of unexpected data types.
