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	8,100+	Clear role definitions in position descriptions are a prerequisite for implementing and enforcing proper access control decisions.
`CWE-269`	Improper Privilege Management	4,000+	Documenting security and privacy duties per position provides the foundation for consistent and correct privilege management across the organization.
`CWE-732`	Incorrect Permission Assignment for Critical Resource	2,000+	Security responsibilities documented in job descriptions guide correct initial and ongoing permission assignments for critical resources.
`CWE-285`	Improper Authorization	1,700+	Explicitly stated responsibilities per position improve the accuracy and consistency of authorization decisions tied to those roles.
`CWE-250`	Execution with Unnecessary Privileges	300+	Position descriptions that explicitly define security responsibilities directly support assignment of only the privileges needed for a role, reducing execution with unnecessary privileges.
`CWE-272`	Least Privilege Violation	43	Incorporating least-privilege expectations into every position description makes violations of the principle harder to occur by default.
