CVE-2023-28640

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.

Always invoking the reference monitor prevents missing authorization checks for protected resources.

Requires verification that authorization checks are present and operational for protected resources.

Requiring explicit authorization for each internal connection prevents missing authorization.

Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly.

Manages privileges by authorizing only approved personnel and supervising those lacking required authorizations for maintenance.

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.

Separating duties such as developing software from administering production systems prevents any one person from accumulating excessive privileges that would constitute improper privilege management.
