Network intrusion protection system definition
A network intrusion protection system is hardware or software measures to protect networks from cyber attacks. These systems constantly monitor networks for threats and automatically take action (such as blocking traffic, killing processes, or quarantining files) when one is detected.
Real network intrusion protection system examples

OpenWIPS-NG is an open-source Linux IPS for wireless networks. It checks suspicious activity for possible intrusion patterns and blocks invaders if necessary.
