A daily monitoring report reveals that an IT employee made a change to a firewall...

Performing an analysis of the change is the first step in addressing the issue of an IT employee making a change to a firewall rule outside of the change control process because it helps to understand the reason, impact, and risk of the change and to decide whether to approve, reject, or reverse it. Requiring that the change be reversed is not the first step because it may cause more disruption or damage without proper analysis and testing. Reviewing the change management process is not the first step because it does not address the specific issue or incident at hand, but rather focuses on improving the process for future changes. Reporting the event to senior management is not the first step because it does not resolve the issue or incident, but rather escalates it without sufficient information or recommendation.
