SonicOS Enhanced 4.0 Administrator Guide
SonicWALL GAV delivers threat protection directly on the SonicWALL security appliance by
matching downloaded or e-mailed files against an extensive and dynamically updated database
of threat virus signatures. Virus attacks are caught and suppressed before they travel to
desktops. New signatures are created and added to the database by a combination of
SonicWALL’s SonicAlert Team, third-party virus analysts, open source developers and other
sources.
SonicWALL GAV can be configured to protect against internal threats as well as those
originating outside the network. It operates over a multitude of protocols including SMTP,
POP3, IMAP, HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and
dozens of other stream-based protocols, to provide administrators with comprehensive network
threat prevention and control. Because files containing malicious code and viruses can also be
compressed and therefore inaccessible to conventional anti-virus solutions, SonicWALL GAV
integrates advanced decompression technology that automatically decompresses and scans
files on a per packet basis.
SonicWALL GAV Multi-Layered Approach
SonicWALL GAV delivers comprehensive, multi-layered anti-virus protection for networks at the
desktop, the network, and at remote sites. SonicWALL GAV enforces anti-virus policies at the
gateway to ensure all users have the latest updates and monitors files as they come into the
network.
