Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Requires validation of information inputs, which structurally stops reliance on untrusted file names or extensions by forcing content-based checks.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require content-based validation instead of trusting file extensions for externally supplied files.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect the weakness, but the control does not guarantee its elimination.

A.8.19 Installation of software on operational systems partial match
degrades

Restricting software installation can limit dangerous file types but does not enforce content-based validation.

A.8.23 Web filtering partial match
degrades

Web filtering can block risky file extensions but does not address server-side file handling logic.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC requires proper file-type validation, directly mitigating reliance on untrusted names or extensions.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate content inspection, but the control itself does not prescribe the technique.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles encourage safe file handling, yet the control is broader than this specific weakness.
