Performing a gap analysis is the best recommendation for a risk practitioner upon learning of an updated cybersecurity regulation that could impact the organization. A gap analysis can help identify the current state of compliance, the desired state of compliance, and the actions needed to achieve compliance. Conducting system testing, implementing compensating controls, and updating security policies are possible actions that may result from the gap analysis, but they arenot the best initial recommendation.
