Network interface device. Not to be confused with Network interface controller. In telecommunications, a network interface device (NID; also known by several other names) is a device that serves as the demarcation point between the carrier's local loop and the customer's premises wiring.
The NIDS can monitor incoming, outgoing, and local traffic. Inspecting outgoing or local traffic can yield valuable insight into malicious activities, just as inspecting incoming traffic can. Some attacks can originate and stay with the local network or be staged inside the network with an outside-the-network target. The NIDS also works with other systems, like a firewall, to help better protect against known attack sources (e.g., a suspected attacker IP address).
