DIACAP (DoD Information Assurance Certification and Accreditation Process) is a Department of Defense (DoD) process that applies to the acquisition, operation, and sustainment of any DoD system that collects, stores, transmits, or processes unclassified or classified information since December 1997. DIACAP is designed to provide a standard process for DoD organizations to identify, implement, and maintain appropriate information assurance (IA) controls and to assess and manage the risk associated with operating DoD information systems.
The following are the six phases of DIACAP:
A. Identification: The identification phase involves identifying the information system and the assets associated with it, as well as the risks that are associated with operating the system. This phase establishes the scope of the IA effort and defines the objectives of the IA activities.
B. System Definition: In the system definition phase, the system is defined in terms of its purpose, capabilities, and security requirements. This phase includes the development of a system security plan (SSP) that describes the security controls that will be implemented to protect the system.
C. Accreditation: The accreditation phase involves the formal assessment of the security controls that have been implemented for the system. This phase includes the development of a risk management framework (RMF) that identifies the controls that are necessary to protect the system and the assessment of those controls to ensure that they are working effectively.
D. Verification: The verification phase involves testing the security controls that have been implemented to ensure that they are working effectively. This phase includes vulnerability testing, penetration testing, and other testing activities to assess the effectiveness of the security controls.
E. Validation: The validation phase involves the formal review and acceptance of the system's security controls. This phase includes the review of the RMF, the SSP, and other documentation to ensure that the system is compliant with DoD IA policies and procedures.
F. Re-Accreditation: The re-accreditation phase involves the periodic reassessment of the system's security controls to ensure that they remain effective. This phase includes the development of a new SSP and the re-assessment of the security controls that have been implemented.
In summary, the DIACAP process includes six phases: Identification, System Definition, Accreditation, Verification, Validation, and Re-Accreditation. These phases are designed to ensure that DoD information systems are secure, that risks are managed effectively, and that IA controls are implemented and maintained to protect DoD information assets.
