DITSCAP Phases for Validating IS

B.

DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process) is a process used by the U.S. Department of Defense to assess and accredit their information systems. It consists of six phases, each with a specific objective.

The phase that validates that the preceding work has produced an Information System (IS) that operates in a specified computing environment is Phase 4: Validation.

Phase 4, also known as Validation, involves a comprehensive review of the information system to ensure that it operates effectively within its intended environment. This phase includes testing the system's functionality, verifying that all security controls are in place and operating as intended, and validating that the system meets all security requirements.

During this phase, the system undergoes a thorough security review to ensure that it is operating correctly and securely. This review involves a range of activities, such as vulnerability testing, penetration testing, and security audits. Once the system has been validated and approved, it is ready for accreditation.

To summarize, the correct answer to the question is A) Phase 4. This phase validates that the preceding work has produced an IS that operates in a specified computing environment. It involves comprehensive testing and review of the system to ensure that all security controls are in place and operating correctly, and that the system meets all security requirements.
