Mitigating Controls (NIST 800-53 r5) AI

SI-15 Information Output Filtering good match

Output filtering/validation directly stops unneutralized formula elements from being written into CSV files.

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 partial match
prevents

Secure SDLC practices directly require output neutralization for untrusted CSV content to block formula injection.

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.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and output encoding that directly prevents formula injection in CSV exports.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for safe CSV generation and handling of untrusted data.

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

Secure architecture principles encourage safe data export design but do not specifically address CSV formula neutralization.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require neutralization of special characters when writing CSV files.

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

Security testing in development can detect formula injection but does not itself implement the mitigation.
