Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Designation of a manager and policy dissemination ensures privileges are assigned according to defined roles.
Regular reviews catch incorrect privilege assignments to users, roles, or processes.
Explicitly specifying privileges and group/role memberships for accounts reduces the risk of incorrect privilege assignments.
The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.
Enforces the least privilege principle to avoid violations of minimal necessary access.
Enforcing only the minimal set of functionality implements least privilege by eliminating unneeded capabilities that could be abused.
The control mandates acknowledgment of least-privilege expectations, making violations by authorized users less likely.
Risk Executive role ensures least privilege is applied uniformly rather than left to individual system owners or projects.
