Protocol Parsers
The Protocol Parsers main functions are to ensure compliance to well-defined protocol standards, detect anomalies if any exist, and assemble the data for further inspection by other components of the IPS engine. They include HTTP, SMTP, DNS, IMAP, Citrix, and many others. In a way, protocol parsers are the heart of the IPS system. They register themselves with the streaming engine (usually PSL), get the streamed data, and dissect the protocol.
