Mitigating Controls (NIST 800-53 r5) AI
Requires digital signature verification before component installation, directly stopping execution of code downloaded without integrity checks.
Least privilege directly requires that only the minimal necessary privileges are assigned to each actor.
Employs integrity verification tools that can identify missing or failed checks on downloaded software after the fact.
Requires documented, valid provenance for components, preventing acceptance of code from outside the trusted sphere.
Account management defines and authorizes the exact privileges granted to each account or role.
Enforces only the authorizations that were assigned, so correct assignment is a prerequisite.
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.
Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.
Directly enforces least-privilege policy definition, management, and review that prevents incorrect privilege assignments.
Supply-chain program directly governs inclusion of third-party executable code.
Contractual requirements can mandate trusted sources and integrity checks for included functionality.
Supplier risk assessment explicitly covers risks from their products and libraries.
Critical-supplier assessment reduces risk of importing executable functionality from untrusted parties.
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.
The access-rights control governs the entire lifecycle of privilege assignment, directly eliminating incorrect assignments.
By requiring suppliers to propagate security requirements and to disclose component provenance, the control limits the inclusion of functionality obtained from untrusted third-party sources without oversight.
Privileged-access-rights control explicitly requires least-privilege assignment and ongoing validation, directly mitigating CWE-266.
Access control policy directly prevents incorrect privilege assignment by defining who may receive which rights.
Segregation of duties reduces blast radius of any single incorrect privilege but does not prevent the assignment itself.
Restricting privileged utility programs limits exposure from over-privileged accounts but does not address how privileges are assigned.
