                Network-Based IDS (NIDS) is a cybersecurity system that monitors network traffic in real-time to identify potential security threats and policy violations. It operates at the network layer, analyzing data as it flows through routers and switches.<\/p>"},{"question":"How does Network-Based IDS work?","answer":"

                NIDS works by using predefined rules or behavioral patterns to identify malicious activities in network traffic. When the system detects matches with these rules or deviations from expected behaviors, it generates alerts for prompt incident response.<\/p>"},{"question":"What are the key features of Network-Based IDS?","answer":"
