Service management is the set of workflows IT teams use to handle incidents, service requests, changes, problems, and other operational tasks. It usually includes ticketing, approvals, prioritization, assignment, escalation, and closure. In practice, it is how alerts, user requests, and maintenance work move through an organization in a controlled way.
In cyber security, service management matters because it turns technical events into accountable action. A good process helps defenders triage incidents quickly, track evidence, coordinate responders, and approve risky changes before they create outages or exposure. It also supports audit trails and access control decisions. In attacks, weak service management can slow response, hide dependency mistakes, or let unsafe changes slip into production. Strong service management makes operations more predictable, more observable, and harder to abuse.
