Explanation

WebSocket is a stateful, full-duplex communication protocol that allows a two-way interactive communication between a Cortex XDR instance and Cortex XDR agents. This type of communication allows data transfers in real-time by keeping sessions for a longer durations. When you perform one of these critical response actions from the Cortex XDR management console, the Cortex XDR instance establishes a session between the instance itself and the targeted endpoint. Then, the session is kept alive even after the response action is complete. Live Terminal is among these response actions.
