Abstract
Methods and systems for processing application-level content of network service protocols are described. According to one embodiment, a network connection is received at a networking subsystem of a firewall. The connection is characterized by a source IP address, a destination IP address and a network service protocol. The network service protocol of the network connection is determined. A matching firewall policy is identified for the connection. When the connection is allowed, it is redirected to a proxy module that is configured to support the network service protocol. A content processing configuration scheme identified by the matching firewall policy is retrieved that includes multiple content processing configuration settings, specifying whether a particular type of content filtering is to be performed, for each of multiple network service protocols. Application-level content of a packet stream associated with the network connection is reconstructed and filtered based on the applicable content processing configuration settings.
