SonicWALL GAV delivers real-time virus protection directly on the SonicWALL security appliance by using SonicWALL’s IPS-Deep Packet Inspection v2.0 engine to inspect all traffic that traverses the SonicWALL gateway. Building on SonicWALL’s reassembly-free architecture, SonicWALL GAV inspects multiple application protocols, as well as generic TCP streams, and compressed traffic. Because SonicWALL GAV does not have to perform reassembly, there are no file-size limitations imposed by the scanning engine. Base64 decoding, ZIP, LHZ, and GZIP (LZ77) decompression are also performed on a single-pass, per-packet basis.
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 is based on SonicWALL's high performance DPIv2.0 engine (Deep Packet Inspection version 2.0) engine, which performs all scanning directly on the SonicWALL security appliance. 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 SonicWALL GAV engine can perform base64 decoding without ever reassembling the entire base64 encoded mail stream. Because 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 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 SonicWALL's reassembly-free architecture, GAV has the ability to inspect multiple application protocols, as well as generic TCP streams, and compressed traffic. SonicWALL GAV protocol inspection is based on high performance state machines which are specific to each supported protocol. 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.

By default, the SonicWALL security appliance running SonicWALL GAV automatically checks the SonicWALL signature servers once an hour. There is no need for an administrator to constantly check for new signature updates. You can also manually update your SonicWALL GAV database at any time by clicking the Update button located in the Gateway Anti-Virus Status section.
SonicWALL GAV signature updates are secured. The SonicWALL security appliance must first authenticate itself with a pre-shared secret, created during the SonicWALL Distributed Enforcement Architecture licensing registration. The signature request is transported through HTTPS, along with full server certificate verification.
Application-level awareness of the type of protocol that is transporting the violation allows SonicWALL GAV to perform specific actions within the context of the application to gracefully handle the rejection of the payload.
By default, SonicWALL GAV inspects all inbound
HTTP
, FTP
, IMAP
, SMTP
and POP3
traffic. Generic TCP Stream
can optionally be enabled to inspect all other TCP based traffic, such as
non-standard ports of operation for SMTP and POP3, and IM and P2P protocols.
Within the context of SonicWALL GAV, the Enable Inbound Inspection protocol traffic handling refers to the following:
|
•
|
|
•
|
SMTP traffic initiating from a Trusted, Wireless, or Encrypted zone destined to a Trusted,
Wireless, or Encrypted zone.
|
The Enable Inbound Inspection protocol traffic handling represented as a table:
The Enable Outbound Inspection feature is available for HTTP, FTP, SMTP, and TCP traffic.
For each protocol you can restrict the transfer of files with specific attributes by clicking on the Settings button under the protocol in the Gateway Anti-Virus Global Settings section.
These restrict transfer settings include:
|
•
|
Restrict Transfer of password-protected Zip files
- Disables the transfer of password protected ZIP files over any enabled protocol. This option only functions on protocols (e.g. HTTP, FTP, SMTP) that are enabled for inspection.
|
|
•
|
Restrict Transfer of MS-Office type files containing macros (VBA 5 and above)
- Disables the transfers of any MS Office 97 and above files that contain VBA macros.
|
Clicking the Configure Gateway AV Settings button at the bottom of the Gateway Anti-Virus Global Settings section displays the Gateway AV Settings window, which allows you to configure clientless notification alerts and create a SonicWALL GAV exclusion list.
If you want to suppress the sending of e-mail messages (SMTP) to clients from SonicWALL GAV when a virus is detected in an e-mail or attachment, check the Disable SMTP Responses box.
The HTTP Clientless Notification feature notifies users when GAV detects an incoming threat from an HTTP server. To configure this feature, check the Enable HTTP Clientless Notification Alerts box and enter a message in the Message to Display when Blocking field, as shown below.
With this option disabled, when GAV detects an incoming threat from an HTTP server, GAV blocks the threat and the user receives a blank HTTP page. Typically, users will attempt to reload the page because they are not aware of the threat. The HTTP Clientless Notification feature informs the user that GAV detected a threat from the HTTP server.
Optionally, you can configure the timeout for the HTTP Clientless Notification on the Security Services > Summary page under the Security Services Summary heading.
Any IP addresses listed in the exclusion list bypass virus scanning on their traffic.The Gateway AV Exclusion List section provides the ability to define a range of IP addresses whose traffic will be excluded from SonicWALL GAV scanning.
To add an IP address range for exclusion, perform these steps:
|
Step 1
|
Click the
Enable Gateway AV Exclusion List
checkbox to enable the exclusion list.
|
|
Step 2
|
|
Step 3
|
