Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and code analysis can locate public non-final clone methods before deployment.

SA-15 Development Process, Standards, and Tools partial match

Documented development standards can mandate secure cloning patterns and final declarations.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can require encapsulation and final methods to block unauthorized object creation paths.

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 mostly match
prevents

Secure SDLC practices directly enforce final clone methods and constructor invariants to block object hijacking.

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 directly require final clone or defensive-copy patterns to block object hijacking.

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

Security testing can detect clone-related state corruption during acceptance testing.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes design and code reviews that can catch non-final clone methods.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate defensive coding rules that prevent unsafe cloning.

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

Secure architecture principles discourage mutable state exposure via cloneable objects.
