A risk assessment is a process that identifies, analyzes, and evaluates the risks that an organization faces in relation to its objectives, assets, and operations. A risk assessment helps to determine the likelihood and impact of potential threats, as well as the adequacy and effectiveness of existing controls. A risk assessment also provides the basis for risk treatment, which involves selecting and implementing the appropriate risk responses, such as avoiding,transferring, mitigating, or accepting the risk. The client’s best course of action in this scenario is to perform their own risk assessment, rather than relying on the third-party service provider’s risk assessment. This is because the third-party service provider may have different risk criteria, assumptions, methods, or perspectives than the client, and may not fully understand or address the client’s specific risk context, needs, and expectations. The third-party service provider’s risk assessment may also be biased, outdated, or inaccurate, and may not reflect the current or future risk environment. By performing their own risk assessment, the client can ensure that the risk of their systems being hacked is properly identified, measured, and managed, and that the risk level is acceptable and aligned with their risk appetite and tolerance. The other options are not the best courses of action for the client, as they may expose the client to unnecessary or unacceptable risk. Implementing additional controls to address the risk may be costly, ineffective, or redundant, and may not be justified by the actual risk level. Accepting the risk based on the third-party service provider’s risk assessment may be risky, as the client may not have a clear or accurate understanding of the risk exposure or consequences. Performing an independent audit of the third party may be useful, but it may not be sufficient or timely to assess and address the risk of the client’s systems being hacked. References = CRISC Review Manual, pages 38-391; CRISC Review Questions, Answers & Explanations Manual, page 792
