An Intrusion Prevention System (IPS) is a network security tool that detects and prevents recognized threats by actively monitoring the network for malicious incidents. Upon detection, it reports events to administrators, triggering preventive actions like closing access points and configuring firewalls. IPS also helps identify issues with corporate security policies, dissuading rule violations. With the rising sophistication of network threats, effective monitoring is essential for swiftly addressing potential violations and incidents in business networks.
