Passive IPS : A passive Intrusion Prevention System (IPS), also known as an IDS (Intrusion Detection System), focuses on monitoring and analyzing network traffic without actively interfering with the traffic flow. It operates in a non-intrusive manner, examining packets and comparing them against predefined signatures or behavioral patterns of known threats. When a potential threat is detected, the passive IPS generates alerts or logs, providing information about the identified threat for further analysis and manual intervention.

Advantages of Passive IPS :

* Non-intrusive monitoring: Passive IPS systems do not interfere with network traffic, allowing uninterrupted data flow.

* Detection and analysis: Passive IPS systems can provide detailed information about potential threats, allowing security analysts to investigate and respond to incidents.

* False positive reduction: Passive IPS systems typically generate alerts or logs for potential threats, allowing human analysis to determine if an action is necessary, reducing false positives.


Disadvantages of Passive IPS :

* Lack of real-time response: Passive IPS systems do not actively block or mitigate threats in real-time, relying on human intervention to respond to detected incidents.

* Delayed response: Since passive IPS systems rely on human analysis and intervention, the response to detected threats can be delayed, potentially allowing some attacks to succeed before they are mitigated.
