Quizplus · Accepted Answer

A NIDS (Network Intrusion Detection System) is designed to detect potential security threats by examining network traffic and looking for suspicious patterns or behaviors that may indicate a threat is present or an attack is underway. It works by analyzing data packets as they move across the network, and comparing them to a set of known threat signatures or behavioral patterns to identify potential threats in real-time. Once a threat is detected, the NIDS can alert security teams, log the event, or even take automated actions to stop the attack and minimize its impact.
