Active IPS : An active Intrusion Prevention System (IPS) is designed to actively block or mitigate detected threats by taking immediate action. It inspects network traffic in real-time, identifies malicious activities or intrusion attempts, and responds by actively blocking or dropping the malicious traffic. Active IPS systems can employ various response techniques, including packet dropping, resetting connections, or triggering alarms.

Advantages of Active IPS :

* Real-time threat prevention: Active IPS systems provide immediate response and mitigation measures, helping to prevent attacks in real-time.

* Proactive defense: By actively blocking or dropping malicious traffic, active IPS systems help protect the network and resources from potential threats.

* Automatic threat response: Active IPS systems can autonomously respond to identified threats without requiring manual intervention.


Disadvantages of Active IPS :

* False positives: Active IPS systems can sometimes incorrectly classify legitimate traffic as malicious, resulting in false positives and potential disruption of valid network communication.

* Network performance impact: The active response actions taken by an active IPS can introduce latency and potentially impact network performance, especially during high traffic volumes or complex attacks.
