You work as a security engineer for BlueWell Inc.
According to you, which of the following DITSCAPNIACAP model phases occurs at the initiation of the project, or at the initial C&A effort of a legacy system.
Click on the arrows to vote for the correct answer
A. B. C. D.B.
The DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process) and its replacement, the NIACAP (National Information Assurance Certification and Accreditation Process), are both security certification and accreditation frameworks for government systems. Both frameworks are composed of six phases that ensure the confidentiality, integrity, and availability of sensitive information.
The six phases of both DITSCAP and NIACAP are:
Definition: The Definition phase is the first phase of the process and occurs at the initiation of the project or initial certification and accreditation (C&A) effort of a legacy system. The purpose of this phase is to define the system's security requirements and identify the security constraints, threats, and vulnerabilities.
Verification: The Verification phase is the second phase of the process and includes the testing of the system to ensure it meets the security requirements identified in the Definition phase.
Validation: The Validation phase is the third phase of the process and involves the validation of the testing results from the Verification phase.
Post Accreditation: The Post Accreditation phase is the fourth phase of the process and includes the ongoing monitoring and evaluation of the system's security posture after it has been accredited.
Maintenance: The Maintenance phase is the fifth phase of the process and involves maintaining the system's security posture by implementing necessary changes and updates.
Decommission: The Decommission phase is the final phase of the process and includes the secure disposal of the system.
Therefore, the correct answer to the question is B. Definition, as it is the first phase of the DITSCAP/NIACAP process and occurs at the initiation of the project or initial C&A effort of a legacy system.
