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.

blocks

Secure development life cycle mandates secure handling of temporary files during design and coding.

blocks

A.8.26 only requires that security requirements (including resilience against injections or input validation) be identified and specified during development or acquisition; it does not itself enforce, implement or configure any mechanism that stops an insecure temporary file from being created or exploited.

blocks

Secure system architecture principles discourage insecure temporary-file patterns but do not directly address them.

prevents

Secure coding standards explicitly require safe temporary-file APIs and permissions.

finds

Security testing can detect insecure temporary files but does not prevent their creation.

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-377, a class-level weakness. Rules are authored against its narrower children: CWE-379.
