Accreditor

D.

The role that is also known as the accreditor is the Designated Approving Authority (DAA).

The DAA is a senior-level official within an organization who has the authority to formally assume responsibility for operating an information system at an acceptable level of risk. The DAA has the ultimate decision-making authority regarding the acceptance of risk associated with an information system and is responsible for ensuring that the system meets all security requirements and is in compliance with applicable laws, regulations, and policies.

The DAA is responsible for conducting a comprehensive risk assessment of the information system and evaluating the risks associated with operating the system. Based on this assessment, the DAA will determine the level of risk that is acceptable and make recommendations for mitigating any identified risks.

The accreditation process involves the DAA making a formal determination that the information system is authorized to operate, based on the results of the risk assessment and any mitigations put in place. The DAA also has the responsibility to periodically review and reauthorize the information system to ensure that it continues to operate at an acceptable level of risk.

In summary, the Designated Approving Authority (DAA) is the role that is responsible for accrediting an information system and ensuring that it operates at an acceptable level of risk.
