Which document includes risk assessment processes as part of the RMF?

The correct document that includes risk assessment processes as part of the Risk Management Framework (RMF) is NIST 800-30. This publication specifically focuses on risk management and outlines the process for conducting risk assessments, which is a crucial component of the risk management lifecycle. NIST 800-30 provides guidelines for identifying, assessing, and mitigating risks to information systems, emphasizing the importance of understanding threats, vulnerabilities, and potential impacts.

While NIST 800-37 is concerned with applying the RMF to manage information security risk and outlines the overall framework, it does not delve into the specifics of conducting risk assessments as extensively as NIST 800-30. NIST 800-53 is primarily focused on security and privacy controls for federal information systems, providing a catalog of controls but not detailing the risk assessment process itself. Similarly, NIST 800-53A offers guidelines for assessing the effectiveness of those controls rather than focusing on the risk assessment process.

Therefore, NIST 800-30 is the most appropriate choice for understanding and implementing risk assessment processes within the context of the RMF.
