The initial security plan for a new application has been approved. What is the next activity in the Risk Management Framework? Response:

Assessing controls (RMF Step 4) occurs after implementation, to determine if they are correctly implemented, operating as intended, and producing the desired outcome.

Assembling the security authorization package (RMF Step 5, Authorize) occurs after controls are implemented and assessed, as the package contains the evidence for the authorization decision.

According to the NIST Risk Management Framework (RMF), after the system security plan is developed and approved (part of the Select step), the next major activity is to implement the security controls specified in that plan. This corresponds to the 'Implement' step (Step 3) of the RMF, where controls are put into place.

Developing a strategy for continuous monitoring (RMF Step 6, Monitor) is the final RMF step, occurring after authorization, to ensure ongoing security.
