EDR — Endpoint Detection and Response
Detection · Intermediate
Software on endpoints that records activity such as processes and network connections and lets responders investigate or isolate a host.
It is more than a signature scan. It keeps a history of what a laptop ran so an analyst can see a suspicious process and isolate that one machine.
Example: A responder isolates a laptop after the endpoint record shows a script launching a tool the user never installs.
Common misconception
- It does not replace patching or backups. It improves visibility and response on the endpoint.
