A. B. C. D.C.
The person responsible for accepting or rejecting the residual risk for a system is the Designated Approving Authority (DAA).
The DAA is a senior official in an organization who is responsible for making decisions regarding the authorization of an information system to operate. This includes making risk-based decisions on whether the residual risk associated with the system is acceptable or not.
Residual risk is the risk that remains after security controls have been implemented. It is the risk that an organization is willing to accept or retain after all efforts have been made to mitigate it.
The DAA reviews the system security plan, security assessment report, and other relevant documents to determine whether the residual risk associated with the system is acceptable or not. The DAA then makes a decision on whether to authorize the system to operate or not based on the residual risk assessment.
The System Owner is responsible for ensuring that the system is operated in accordance with its security requirements, while the Information Systems Security Officer (ISSO) is responsible for implementing and maintaining the security controls for the system. The Chief Information Security Officer (CISO) is responsible for the overall security of the organization's information systems.
In summary, the DAA is responsible for accepting or rejecting the residual risk associated with a system. The other roles, such as the System Owner, ISSO, and CISO, have different responsibilities related to the security of the system and the organization as a whole.
