Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.
Implements core proper privilege management by restricting to only required rights.
Baseline configuration documents and controls privilege assignments, making improper privilege management harder to introduce or sustain.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
Defines roles and responsibilities to ensure proper privilege management during configuration changes.
Designates roles and review processes for managing physical privileges and access rights.
Tailoring explicitly overrides or scopes default permission assignments in the baseline to match the system's actual risk and operational needs.
Centralized privilege assignment and oversight prevent ad-hoc or excessive privilege grants that occur when each system is configured independently.
