Weaknesses this control addresses (6)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-284 | Improper Access Control | 6,900+ | Periodic purpose analysis directly detects and corrects access control decisions that permit use outside the defined mission function. |
CWE-269 | Improper Privilege Management | 3,400+ | Drives ongoing review and correction of privilege assignments that have drifted from intended operational need. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 1,900+ | Triggers re-evaluation of permission assignments on critical resources when usage deviates from declared purpose. |
CWE-285 | Improper Authorization | 1,500+ | Enforces that authorization rules remain consistent with the documented intended purpose of each resource. |
CWE-250 | Execution with Unnecessary Privileges | 300+ | Identifies privileges or capabilities that exceed what is required for the stated mission purpose, enabling removal. |
CWE-653 | Improper Isolation or Compartmentalization | 73 | Verifies that mission-essential functions remain isolated and not repurposed across compartment boundaries. |
