A network operations team applied an emergency configuration update to several core routers during production hours, causing an unexpected outage. Management later discovered that the change was neither logged in the ticketing system nor reviewed by the appropriate stakeholders.
Which governance procedure, if properly followed, would most likely have prevented this outage?
Change Management establishes a formal process that requires proposed modifications to be recorded, risk-assessed, reviewed, and approved before implementation. By following this procedure, the team would have submitted the update for evaluation, obtained authorization, scheduled the work in a maintenance window, and documented the change-steps that collectively reduce the chance of service disruption. Incident Response focuses on reacting after an event, Acceptable Use Policy governs end-user behavior, and Business Continuity Planning addresses maintaining critical functions during major disruptions; none of these directly enforce the gating and documentation of routine configuration changes.
