CVE-2020-3250

Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.

Access supervision ensures privileges are assigned and managed without improper escalation or retention.

Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.

Enforces proper privilege management by requiring all decisions through the verified reference monitor.

By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.

Implements core proper privilege management by restricting to only required rights.

Policy requires training on privilege management and least privilege, making it harder to exploit improper privilege management weaknesses.

Training covers proper privilege management practices, making incorrect privilege assignments less likely.

PR.AA-01 supplies credential/identity lifecycle support that can reduce some privilege-assignment errors but does not itself assign, modify, or check privileges, leaving most of CWE-269's risk unaddressed.

Config baselines and default reviews can enforce some privilege-related settings (one facet) but do not address code-level assignment/tracking logic that defines CWE-269.

PR.PS-05 can partially limit exploitability of some privilege issues via execution restrictions, but does not address the core design/implementation flaws of CWE-269 at all.

Explicit restrictions on privileged access and segregation of duties limit the scope of privileges that can be assigned, reducing the chance that excessive or unnecessary privileges are granted to entities.

Defining and communicating authorization levels for each role limits the assignment of excessive or unnecessary privileges.
