Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Requires establishing the most restrictive configuration settings, which directly overrides or prevents use of insecure default variable initializations.

CM-2 Baseline Configuration good match

Requires maintaining a documented baseline configuration that can enforce secure initial values instead of insecure defaults.

SA-8 Security and Privacy Engineering Principles partial match

Mandates application of security engineering principles during development that include use of secure defaults and proper variable initialization.

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-01 mostly match

prevents

Hardened baselines and configuration management directly replace insecure product defaults with secure values.

PR.PS-06 mostly match

prevents

Secure software development practices explicitly include choosing safe initial values instead of insecure defaults.

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 insecure defaults but does not prevent them.

A.8.9 Configuration management mostly match

prevents

Configuration management enforces secure default values and prevents insecure initialization.

A.8.25 Secure development life cycle partial match

prevents

Secure development life cycle requires explicit secure initialization of variables.

A.8.27 Secure system architecture and engineering principles partial match

prevents

Secure architecture principles include avoiding insecure defaults in design.
