Mitigating Controls

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.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle includes type-safety reviews that reduce incorrect casts.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against attacks such as buffer overflows or SQL injection) be identified and specified during development or acquisition; it does not itself enforce, implement, or prevent any type-conversion defects from arising or being exploitable.

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

Secure architecture principles discourage unsafe type conversions in design.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid or detect incorrect type casts.

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

Security testing can uncover type-conversion defects before release.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-704, a class-level weakness, and none of its children carries one either.
