Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
A tamperproof reference monitor ensures security tokens cannot be improperly assigned or altered outside policy.
Access enforcement directly requires that security tokens used for authorization decisions are protected from unauthorized assignment or modification.
Isolating security functions from non-security functions reduces the attack surface for tampering with token assignment logic.
Security attributes (tokens) must be associated and maintained with subjects/objects, which structurally prevents improper assignment or lack of protection.
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.
Proper definition and enforcement of authorizations directly addresses improper security token restrictions.
Pre-acquisition hardware integrity checks can detect flawed token protection mechanisms before deployment.
Logical access protections can prevent exploitation of improperly assigned hardware security tokens.
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.
Privileged access rights help ensure only authorized processes can assign or modify tokens.
Security testing can detect improper token assignment but does not prevent it at design time.
Information access restriction directly limits which entities can obtain or use security tokens.
Secure architecture principles can guide token protection mechanisms but do not enforce assignment rules.
Secure coding practices reduce the likelihood of token-assignment bugs but do not define the policy.
Cryptography can protect token confidentiality but does not address improper assignment logic.
