Which Registration Task Notifies DAA, Certifier, and User Representative of C&A Support Requirement?

D.

In the context of the Certification and Accreditation (C&A) process, Registration Tasks refer to the steps involved in initiating the C&A process for a new or updated system. The C&A process is designed to ensure that information systems are secure and that they comply with relevant security requirements.

The answer to this question is C. Registration Task 3. This is because Registration Task 3 involves notifying the Designated Accreditation Authority (DAA), Certifier, and User Representative that the system requires C&A support.

Registration Task 3 typically involves the following steps:

1. Identification of the system: This step involves identifying the system that requires C&A support. This includes defining the system boundaries and identifying the hardware, software, and data components of the system.

2. Determination of the C&A category: This step involves determining the appropriate C&A category for the system. The C&A category is based on the system's security impact level, which is determined by the system's potential impact on the organization's mission or business processes.

3. Notification of the DAA, Certifier, and User Representative: This step involves notifying the DAA, Certifier, and User Representative that the system requires C&A support. The notification should include information about the system, such as its security impact level and any known security vulnerabilities.

4. Initiation of the C&A process: Once the DAA, Certifier, and User Representative have been notified, the C&A process can be initiated. This typically involves conducting a risk assessment, developing a security plan, and conducting security testing and evaluation.

In summary, Registration Task 3 is the correct answer because it involves notifying the DAA, Certifier, and User Representative that the system requires C&A support, which is a critical step in initiating the C&A process.
