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.
Secure development practices directly address proper workflow enforcement during design and coding.
Enforcing authorization policies can include sequence constraints on multi-step actions.
Hardened configuration baselines can embed required workflow ordering rules.
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.
Security testing can detect workflow bypasses but does not enforce them at runtime.
Secure development lifecycle requires explicit workflow enforcement in multi-step processes.
Application security requirements include sequencing and state-transition rules for critical workflows.
Secure architecture principles address proper ordering of security-critical operations.
Secure coding practices can prevent missing workflow checks but do not define the control itself.
Change management can require workflow adherence for changes but is not the primary mitigation.
