What type of information does a real-time-based IDS collect?

A real-time-based Intrusion Detection System (IDS) is designed to monitor network traffic continuously and provide immediate alerts regarding potential threats or suspicious activities as they occur. This dynamic capability enables the IDS to analyze incoming data packets in real-time, allowing for the detection of anomalies or intrusion attempts as they happen.

The focus on regular and real-time information from network traffic streams is crucial because it empowers security teams to respond swiftly to incidents, minimizing potential damage. Such systems can identify patterns, log events, and trigger alerts based on predefined conditions, making them valuable tools for maintaining network security on an ongoing basis.

Other types of information, like historical data or static snapshots, have their uses but do not capture the immediate state of the network, which is essential for rapid threat detection and response. Collecting information solely from IoT devices also limits the scope of monitoring, as a comprehensive real-time IDS should assess a wide range of traffic from various network sources to effectively safeguard the entire network environment.
