| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-284 | Improper Access Control | 6,900+ | POA&M process requires documented remedial actions and tracking for identified access control deficiencies until resolved per risk priorities. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 1,900+ | Drives systematic identification, documentation, and closure of incorrect critical-resource permission assignments through tracked milestones. |
CWE-285 | Improper Authorization | 1,500+ | Ensures authorization weaknesses discovered via assessments are captured with concrete remediation plans aligned to organizational risk strategy. |
