Intrusion Prevention System - Classifications

Classifications

Intrusion prevention systems can be classified into four different types:

Network-based intrusion prevention system (NIPS): monitors the entire network for suspicious traffic by analyzing protocol activity.

Wireless intrusion prevention systems (WIPS): monitors a wireless network for suspicious traffic by analyzing wireless networking protocols.

Network behavior analysis (NBA): examines network traffic to identify threats that generate unusual traffic flows, such as distributed denial of service (DDoS) attacks, certain forms of malware, and policy violations.

Host-based intrusion prevention system (HIPS): an installed software package which monitors a single host for suspicious activity by analyzing events occurring within that host.
