Evidence Types and Assessment Approaches for AC.L2-3.1.1 Assessment Objective [b]

Ranking of Evidence Types for Assessment Objective [b]

For the assessment objective "[b] processes acting on behalf of authorized users are identified," I recommend prioritizing evidence types in this order:

1. **Artifacts**: System-generated lists of automated processes, service accounts, scheduled tasks, and process ownership records provide the strongest direct evidence of how processes acting on behalf of users are identified and tracked within the system.

2. **Documents**: Documentation that defines policies and procedures for managing automated processes, service accounts, and scheduled tasks that act on behalf of users.

3. **Screen Share**: Observing administrators demonstrating how processes and service accounts are configured, monitored, and associated with authorized users.

4. **Physical Review**: On-site examination would be less valuable for this objective, as processes are primarily digital entities.

Prioritizing Assessment Approaches

For assessment objective [b], I recommend prioritizing the three assessment approaches as follows:

1. **Test**: This should be your primary approach for this objective because processes acting on behalf of users are technical in nature:

  - Examine system mechanisms that track process ownership
  - Verify that automated tasks are properly associated with authorizing users
  - Check system logs that show process attribution to users
  - Test process authentication mechanisms
  - Verify that service accounts are properly configured and documented

2. **Examine**: Follow with document examination to verify formal documentation:

  - Review system configuration settings that manage process authorization
  - Examine documentation of automated processes and service accounts
  - Review policies for process creation and management
  - Check system records that map processes to authorizing users
  - Examine audit logs showing process attribution

3. **Interview**: Complete your assessment with targeted interviews:

  - Speak with system administrators who configure automated processes
  - Interview security personnel about process authorization controls
  - Discuss with IT staff how they track and manage processes acting on behalf of users

This prioritization reflects the technical nature of this assessment objective, where seeing the actual implementation and technical controls in action provides the most direct evidence that processes acting on behalf of users are properly identified and tracked within the system.
