Definitions
The time it takes to begin or complete a response action after an alert, request, or incident is recognized. In security operations, response time is a practical measure of whether detection and staffing actually translate into timely defensive action.
In plain English: How long it takes to react to a security event or request.
Example: "The new on-call workflow cut response time for high-confidence credential theft alerts from forty minutes to under five."
