Master Assessment Datasheet

Implementation Guidance

The organization being inspected/assessed identifies unauthorized use of the information system through techniques and methods defined in SI-4, CCI 2645. The organization must maintain an audit trail of identified instances of unauthorized use.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the audit trail of identified instances of unauthorized use to ensure the organization being inspected/assessed identifies unauthorized use of the information system through techniques and methods defined in SI-4, CCI 2645.

Compelling Evidence

1.) Audit trail of identified instances of unauthorized use to ensure the site identifies unauthorized use of the information system through techniques and methods defined in SI-4, CCI 2645.
