Configuring Gateway AV/IPS
Gateway AntiVirus settings
1
Select the Enable Gateway AntiVirus for HTTP check box to scan HTTP content, which your
users try to download, for viruses.
2
Select the Enable Gateway AntiVirus for FTP check box to scan file transfer traffic for viruses.
3
Select the Enable Gateway AntiVirus for POP3 check box to scan email downloaded from the
email server for viruses.
4
Select the Enable Gateway AntiVirus for SMTP check box to scan email sent to an email server
protected by your Edge for viruses.
5
There is a very large set of file formats used on the Internet. Use the When an error is
encountered drop-down list to select the action you want Gateway AV to take when it cannot
successfully scan a file. The default action is Remove .
6
Select the Limit Scanning check box if you want the Gateway AV service to stop scanning each
file after it examines the specified number of kilobytes. This improves the performance of the
Edge. Most viruses are small and many are in the first hundred kilobytes of a file. You must select
the correct balance of performance and security for your network.
