CWE Name CVEs Why this control addresses it
CWE-284Improper Access Control4,832Personnel screening before access authorization directly strengthens access control decisions and reduces the chance that unvetted individuals can exploit improper access control weaknesses.
CWE-269Improper Privilege Management2,907Vetting individuals before privilege assignment lowers the likelihood that privileges will be given to people who will misuse them, directly mitigating improper privilege management.
CWE-285Improper Authorization1,230Screening 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-250Execution with Unnecessary Privileges305Screening supports assignment of access only to those who have been evaluated, reducing execution with unnecessary privileges by untrusted or unqualified personnel.
