Implementation Guidance

The organization being inspected/assessed documents and implements a process to verify in an operational environment, following changes to the information system, the security functions are implemented correctly. The organization must maintain an audit trail of the verification of security functions.

Validation Procedures

The organization conducting the inspection/assessment obtains and examines the documented process as well as the audit trail of the verification of security functions to ensure the organization being inspected/assessed verifies in an operational environment, following changes to the information system, the security functions are implemented correctly.

Compelling Evidence

1.) Signed and dated documentation of a process to verify that after changes to the information system are completed, the security functions are implemented correctly in an operational environment. 2.) Audit trail of the verification of security functions.
