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.
