Assessment Objective

Determine if:

• system access for users (or processes acting on behalf of users) is authorized only when necessary to accomplish assigned organizational tasks.
• access to [Assignment: security functions] is authorized.
• access to [Assignment: security-relevant information] is authorized.
• the privileges assigned to roles or classes of users are reviewed [Assignment: frequency] to validate the need for such privileges.
• privileges are reassigned or removed, as necessary.

Assessment Methods

Examine

• access control policy and procedures
• procedures for least privilege
• list of assigned access authorizations (i.e., privileges)
• system configuration settings
• system audit records
• list of security functions (implemented in hardware, software, and firmware)
• security-relevant information for which access must be explicitly authorized
• list of system-generated roles or classes of users and assigned privileges
• validation reviews of privileges assigned to roles or classes of users
• records of privilege removals or reassignments for roles or classes of users
• system security plan
• system design documentation
• other relevant documents or records

Interview

• personnel with responsibilities for defining least privileges
• personnel with information security responsibilities
• system administrators

Test

• mechanisms for implementing least privilege functions
• mechanisms for implementing reviews of user privileges
