Dell SonicWALL GAV Architecture

Dell SonicWALL GAV is based on Dell SonicWALL's high performance DPIv2.0 engine (Deep Packet Inspection version 2.0) engine, which performs all scanning directly on the Dell SonicWALL security appliance. Dell SonicWALL GAV includes advanced decompression technology that can automatically decompress and scan files on a per packet basis to search for viruses and malware. The Dell SonicWALL GAV engine can perform base64 decoding without ever reassembling the entire base64 encoded mail stream. Because Dell SonicWALL's GAV does not have to perform reassembly, there are no file-size limitations imposed by the scanning engine. Base64 decoding and ZIP, LHZ, and GZIP (LZ77) decompression are also performed on a single-pass, per-packet basis. Reassembly free virus scanning functionality of the Dell SonicWALL GAV engine is inherited from the Deep Packet Inspection engine, which is capable of scanning streams without ever buffering any of the bytes within the stream.

Building on Dell SonicWALL's reassembly-free architecture, GAV has the ability to inspect multiple application protocols, as well as generic TCP streams, and compressed traffic. Dell SonicWALL GAV protocol inspection is based on high performance state machines which are specific to each supported protocol. Dell SonicWALL GAV delivers protection by inspecting over the most common protocols used in today's networked environments, including SMTP, POP3, IMAP, HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and dozens of other stream-based protocols. This closes potential backdoors that can be used to compromise the network while also improving employee productivity and conserving Internet bandwidth.
