Weaknesses this control addresses (10)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-862 | Missing Authorization | 10,200+ | Requiring an access control policy ensures authorization checks are defined and applied for critical functions. |
CWE-284 | Improper Access Control | 6,900+ | The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization. |
CWE-863 | Incorrect Authorization | 3,900+ | Periodic review and update of procedures reduces incorrect authorization implementations over time. |
CWE-269 | Improper Privilege Management | 3,400+ | Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 1,900+ | Procedures support proper permission assignment for critical resources through documented controls. |
CWE-276 | Incorrect Default Permissions | 1,800+ | Access control policy can specify and enforce secure default permissions for resources. |
CWE-285 | Improper Authorization | 1,500+ | Documented procedures facilitate correct implementation and ongoing management of authorization decisions. |
CWE-266 | Incorrect Privilege Assignment | 1,000+ | Designation of a manager and policy dissemination ensures privileges are assigned according to defined roles. |
