Mitigating Controls

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.AA-05 mostly match
prevents

Defining and enforcing least-privilege access permissions directly prevents unauthorized export of Android components.

PR.PS-06 mostly match
prevents

Secure SDLC practices include configuring component exports and permission checks to avoid this weakness.

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.8.28 Secure coding mostly match
prevents

Secure-coding standards require explicit permission declarations and intent-filter restrictions to avoid improper exports.

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

Security testing can detect exported components lacking proper restrictions, providing partial coverage of the weakness.

A.8.3 Information access restriction mostly match
prevents

Enforcing information-access restrictions on exported Android components directly prevents unauthorized launch or data access.

A.8.26 Application security requirements partial match
prevents

Defining application security requirements includes specifying proper export restrictions and permission checks for components.

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

Secure architecture principles discourage overly permissive component exports, though the control is broader than this single weakness.
