ITSM
Abbreviation · Security & Infosec
Definitions
Short for IT service management, the discipline of delivering and controlling IT services through processes such as incident management, change management, requests, and problem management. In security work, ITSM often matters because many security actions depend on approved changes and tracked service workflows.
In plain English: A structured way of running and managing IT services and support processes.
Example: "The containment plan had to fit the ITSM process so emergency changes could still be documented properly."
