Which of the following tasks is associated with Step 6 of RMF?

Step 6 of the Risk Management Framework (RMF) focuses on the importance of maintaining the security posture of information systems throughout their lifecycle. This step is primarily concerned with continuous monitoring, which includes evaluating changes within the system environment.

Assessing the security impact of proposed changes is a critical task in this step, as it ensures that any adjustments made to the system—such as updates, modifications, or new integrations—do not inadvertently introduce vulnerabilities or increase risk. By conducting this assessment, organizations can document risks associated with changes and implement necessary measures to mitigate them effectively, thereby maintaining a strong security posture.

While tasks like documenting control implementation, developing the system authorization package, and submitting the security assessment report are important components of the overall RMF process, they are associated with different steps in the RMF. Step 6 specifically revolves around the ongoing assessment and monitoring of security measures relative to changes in the system environment, which is why assessing the security impact of proposed changes is the correct task associated with this step.
