 Protocol-based intrusion detection system

A protocol-based intrusion detection system (PIDS) is an intrusion detection system which is typically installed on a web server, and is used in the monitoring and analysis of the protocol in use by the computing system.A PIDS will monitor the dynamic behavior and state of the protocol and will typically consist of a system or agent that would typically sit at the front end of a server, monitoring and analyzing the communication between a connected device and the system it is protecting.
