Click on the arrows to vote for the correct answer
A. B. C. D.D.
The correct order of the Certification and Accreditation (C&A or CnA) phases in a DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process) assessment is:
C. Verification, Validation, Definition, and Post Accreditation
Let's break down each phase of the DITSCAP assessment process:
Definition phase: During this phase, the scope and security requirements of the system are defined. The system owner and security personnel collaborate to define the system's security goals and objectives. This phase also includes identifying the critical components of the system and the type of data that the system will handle.
Verification phase: In this phase, the security personnel verifies whether the system complies with the security requirements identified in the definition phase. Security personnel may use various tools such as vulnerability scanners, penetration testing, and risk assessments to ensure the system's security. The verification phase also includes identifying any vulnerabilities or weaknesses that need to be addressed.
Validation phase: During this phase, the security personnel validates that the system meets the security requirements identified in the definition phase. The validation phase includes testing and evaluating the system's security controls to ensure that they are working correctly. The validation phase also ensures that the system's security requirements are met and that the system is ready for accreditation.
Post Accreditation phase: This phase involves continuous monitoring of the system after it has been accredited. Security personnel continually assess and evaluate the system to ensure that it maintains its security posture. The post-accreditation phase also includes periodic assessments of the system to ensure that it remains compliant with security policies and regulations.
In conclusion, the correct order of the C&A phases in a DITSCAP assessment is Verification, Validation, Definition, and Post Accreditation (Option C). The verification phase ensures that the system complies with security requirements, the validation phase confirms that the system meets those requirements, and the definition phase defines the requirements. The post-accreditation phase involves continuous monitoring to ensure that the system remains secure.
