Question
Which type of IDS monitors network traffic for particular network segments or devices?
Solution
The type of Intrusion Detection System (IDS) that monitors network traffic for particular network segments or devices is known as a Network-based IDS (NIDS).
Here are the steps explaining how it works:
-
Deployment: The NIDS is deployed at a strategic point or points within the network where it can monitor inbound and outbound traffic to and from all the devices it is intended to protect.
-
Traffic Analysis: The NIDS analyses the network traffic for suspicious activity. This could be anything that deviates from the norm such as unusual traffic patterns or protocol violations.
-
Alert Generation: If the NIDS detects suspicious activity, it generates an alert and notifies the network administrators. The alert could also trigger a response to block the suspicious traffic.
-
Traffic Logging: The NIDS also logs traffic for future analysis. This can help in identifying patterns and improving the system's detection capabilities.
-
Update: The NIDS is regularly updated with new threat information to ensure it can detect the latest attacks.
