Weaknesses this control addresses (4)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+ | Personnel screening before access authorization directly strengthens access control decisions and reduces the chance that unvetted individuals can exploit improper access control weaknesses. |
CWE-269 | Improper Privilege Management | 3,400+ | Vetting individuals before privilege assignment lowers the likelihood that privileges will be given to people who will misuse them, directly mitigating improper privilege management. |
CWE-285 | Improper Authorization | 1,500+ | Screening verifies trustworthiness prior to granting rights, making it harder for attackers to exploit improper authorization by placing malicious or unqualified personnel in authorized roles. |
CWE-250 | Execution with Unnecessary Privileges | 300+ | Screening supports assignment of access only to those who have been evaluated, reducing execution with unnecessary privileges by untrusted or unqualified personnel. |
