What framework should a risk auditor contracted by a U.S. government agency use for risk assessments?

The National Institute of Standards and Technology (NIST) Risk Management Framework (RMF) is specifically designed to help U.S. federal agencies manage cybersecurity risk. This framework provides a structured approach that integrates security and risk management activities into the system development lifecycle.

Using the NIST RMF ensures compliance with the Federal Information Security Management Act (FISMA) and aligns with the federal government's requirements for cybersecurity. The framework emphasizes continuous monitoring, assessment, and improvement of risk management processes, which is crucial for maintaining the security of government information systems.

In contrast, while other frameworks like ISO 31000, COBIT, and COSO have valuable risk management concepts, they are not specifically tailored to the unique regulatory and operational context of U.S. government agencies. ISO 31000 provides general guidelines on risk management but lacks the specificity required for federal compliance. COBIT primarily focuses on IT governance and management rather than specifically on risk assessment, and COSO is concerned with internal controls and enterprise risk management but does not address the specific requirements of government cybersecurity frameworks. Therefore, for a risk auditor working with U.S. government agencies, the NIST RMF is the most appropriate choice for conducting risk assessments.
