An intrusion prevention system (IPS) is a network security tool (which can be a hardware device or software) that continuously monitors a network for malicious activity and takes action to prevent it, including reporting, blocking, or dropping it, when it does occur.

Honeypot: A honeypot in security is a trap set to lure or trap hackers. This can be done by using a decoy or false data, a fake server, or a false user. A honeypot can help an administrator learn more about their hacker and attack patterns.
