The DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process) is a systematic approach to assess and certify the security posture of DoD (Department of Defense) information systems. The DITSCAP consists of six phases, and Phase 4 is called Post Accreditation.
Phase 4: Post Accreditation
Phase 4 starts after the system has been accredited in Phase 3. The primary objective of Phase 4 is to maintain the system's security posture and ensure that the system continues to operate in a secure and compliant manner. The process activities of Phase 4 are as follows:
A. Security operations: This activity includes monitoring and maintaining the system's security posture and detecting and responding to security incidents.
B. Continue to review and refine the SSAA: The System Security Authorization Agreement (SSAA) is a critical document that describes the security posture of the system. In Phase 4, the SSAA must be reviewed and updated to reflect any changes in the system or its environment.
C. Change management: This activity includes assessing the security impact of proposed changes to the system and implementing security controls to mitigate any risks associated with those changes.
D. Compliance validation: This activity includes conducting periodic reviews and audits to ensure that the system continues to comply with all applicable security policies, standards, and regulations.
E. System operations: This activity includes maintaining the system's hardware and software components, performing backups and restores, and ensuring that the system is available when needed.
F. Maintenance of the SSAA: This activity includes updating the SSAA as necessary to reflect any changes in the system or its environment.
In summary, Phase 4 of the DITSCAP C&A process is critical to ensuring the ongoing security and compliance of the system. The process activities of Phase 4 must be carefully planned and executed to maintain the system's security posture and ensure that it continues to operate in a secure and compliant manner.
