Explanation

A Network-based IDS (NIDS) is deployed at strategic points on the network (e.g., near routers or firewalls) and captures/analyzes packet traffic in real time to detect suspicious activity. A host-based IDS (HIDS) monitors logs and activity on a single host rather than the network. Application-based IDS focuses on a specific application's behavior. 'Firewall-based IDS' is not a standard classification - firewalls filter traffic by rules but are not IDSs.
