Who approves the final authorization of a system based on risk assessments?

The final authorization of a system based on risk assessments is typically the responsibility of the Authorizing Official. This individual is tasked with the important role of evaluating and accepting the risk associated with the system's operation based on the information provided in the risk assessment, which includes various factors such as security controls, vulnerabilities, and potential impacts on the organization.

The Authorizing Official must have a comprehensive understanding of both the technical and organizational aspects of the system, including its compliance with applicable regulations and policies. This role is essential in ensuring that risks are managed according to the organization's risk tolerance, thereby facilitating informed decision-making about the security posture of the system prior to its deployment or operation within the organization.

The Chief Information Security Officer, while influential in establishing security policies and frameworks, does not typically grant final authorization alone. The Compliance Officer focuses on adherence to laws and regulations and may provide necessary insights but does not carry the authority to approve system authorization directly. The Risk Management Team plays an advisory role in identifying and assessing risks, but they do not have the authority to grant final authorization either. Therefore, selecting the Authorizing Official is the appropriate designation for this responsibility.
