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.

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.
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.

Activating the SonicWALL Gateway Anti-Virus license on your SonicWALL security appliance
does not automatically enable the protection. To configure SonicWALL Gateway Anti-Virus to begin protecting your network, you need to perform the following steps:
The
Security Services > Gateway Anti-Virus
page provides the settings for configuring SonicWALL GAV
on your SonicWALL security appliance.
You must select
Enable Gateway Anti-Virus
check box in the Gateway Anti-Virus Global
Settings
section to enable SonicWALL GAV on your SonicWALL security appliance.You must specify the zones you want SonicWALL GAV protection on the Network > Zones

You apply SonicWALL GAV to zones on the
Network > Zones
page.
You can enforce SonicWALL GAV not only between each network zone and the WAN, but also
between internal zones. For example, enabling SonicWALL GAV on the LAN zone enforces anti-virus protection on all incoming and outgoing LAN traffic.
|
Step 2
|
In the
Configure
column in the Zone Settings
table, click the edit icon  . The Edit Zone
window is displayed.
|
|
Step 3
|
Click the

|
|
Note
|
You also enable SonicWALL GAV protection for new zones you create on the Network >
Zones
page. Clicking the Add
button displays the Add Zone
window, which includes the same settings as the Edit Zone
window.
|
The
Gateway Anti-Virus Status
section shows the state of the anti-virus signature database, including the database's timestamp, and the time the SonicWALL signature servers were last checked for the most current database version. The SonicWALL security appliance automatically attempts to synchronize the database on startup, and once every hour.
The
Gateway Anti-Virus Status
section displays the following information:
|
|
•
|
Signature Database
indicates whether the signature database needs to be downloaded or has been downloaded.
|
|
|
•
|
Signature Database Timestamp
displays the last update to the SonicWALL GAV signature database, not the last update to your SonicWALL security appliance.
|
|
|
•
|
Last Checked
indicates the last time the SonicWALL security appliance checked the signature database for updates. The SonicWALL security appliance automatically attempts to synchronize the database on startup, and once every hour.
|
|
|
•
|
Gateway Anti-Virus Expiration Date
indicates the date when the SonicWALL GAV service expires. If your SonicWALL GAV subscription expires, the SonicWALL IPS inspection is stopped and the SonicWALL GAV configuration settings are removed from the SonicWALL security appliance. These settings are automatically restored after renewing your SonicWALL GAV license to the previously configured state.
|
The
Gateway Anti-Virus Status
section displays Note: Enable the Gateway Anti-Virus per
zone from the
Network > Zones
page
. Clicking on the Network > Zones
link displays the Network > Zones
page for applying SonicWALL GAV on zones.
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:
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 packed executable files (UPX, FSG, etc.)
- Disables the transfer of packed executable files. Packers are utilities which compress and sometimes encrypt executables. Although there are legitimate applications for these, they are also sometimes used with the intent of obfuscation, so as to make the executables less detectable by anti-virus applications. The packer adds a header that expands the file in memory, and then executes that file. SonicWALL Gateway Anti-Virus currently recognizes the most common packed formats: UPX, FSG, PKLite32, Petite, and ASPack. additional formats are dynamically added along with SonicWALL GAV signature updates.
|
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.
|
|
Tip
|
The HTTP Clientless Notification feature is also available for SonicWALL Anti-Spyware.
|
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.
