You work as a security engineer for BlueWell Inc. According to you, which of the following DITSCAP/NIACAP model phases occurs at the initiation of the project, or at the initial C&A effort of a legacy system?
Suggested Answer:B🗳️
The definition phase of the DITSCAP/NIACAP model takes place at the beginning of the project, or at the initial C&A effort of a legacy system. C&A consists of four phases in a DITSCAP assessment. These phases are the same as NIACAP phases. The order of these phases is as follows: 1.Definition: The definition phase is focused on understanding the IS business case, the mission, environment, and architecture. This phase determines the security requirements and level of effort necessary to achieve Certification & Accreditation (C&A). 2.Verification: The second phase confirms the evolving or modified system's compliance with the information. The verification phase ensures that the fully integrated system will be ready for certification testing. 3.Validation: The third phase confirms abidance of the fully integrated system with the security policy. This phase follows the requirements slated in the SSAA. The objective of the validation phase is to show the required evidence to support the DAA in accreditation process. 4.Post Accreditation: The Post Accreditation is the final phase of DITSCAP assessment and it starts after the system has been certified and accredited for operations. This phase ensures secure system management, operation, and maintenance to save an acceptable level of residual risk.
B. Definition occurs at the initiation of the project or at the initial C&A effort of a legacy system in DITSCAP/NIACAP model phases as it includes defining security requirements and conducting a risk analysis.
