As the plan is executed and the controls and system are implemented, the system is tested to validate the strength of those controls.
Phase 3 - Certify & Accredit: Once the security controls have been implemented and the testing has been completed, the IA team works with the Certifying Authority (CA); or the designed Agent of the Certifying Authority (ACA) so they can make a decision on Accreditation of the system in...
