6Select OK.

Updating antivirus and IPS signatures

Configure the FortiGate unit to connect to the FortiGuard Distribution Network (FDN) to update the antivirus (including grayware), antispam and IPS attack definitions.

The FDN is a world wide network of FortiGuard Distribution Servers (FDS). When the FortiGate unit connects to the FDN, it connects to the nearest FDS. To do this, all FortiGate units are programmed with a list of FDS addresses sorted by nearest time zone according to the time zone configured for the FortiGate unit.

You can update your antivirus and IPS signatures using the web-based manager or the CLI. Before you can begin receiving updates, you must register your FortiGate unit from the Fortinet web page.

Note: Update AV and IPS signatures on a regular basis. If you do not update AV and IPS signatures regularly, the FortiGate unit can become vulnerable to new viruses.

After registering your FortiGate unit, verify the FortiGate unit can connect to the FDN:

•Check that the FortiGate unit’s system time is correct.

•From the web-based manager, select refresh from the FortiGuard Center.

If you cannot connect to the FDN, follow the procedure for registering your FortiGate unit and try again or see “Adding an override server” on page 49.

Updating antivirus and IPS signatures from the web-based manager

After you have registered your FortiGate unit, you can update antivirus and IPS signatures using the web-based manager. The FortiGuard Center enables you to receive push updates, allow push update to a specific IP address, and schedule updates for daily, weekly, or hourly intervals.

To update antivirus definitions and IPS signatures

1Go to System > Maintenance > FortiGuard Center.

2Select the blue arrow for AntiVirus and IPS Downloads to expand the options.

3Select Update Now to update the antivirus definitions.

If the connection to the FDN is successful, the web-based manager displays a message similar to the following:

Your update request has been sent. Your database will be updated in a few minutes. Please check your update page for the status of the update.

After a few minutes, if an update is available, the System FortiGuard Center page lists new version information for antivirus definitions. The System Status page also displays new dates and version numbers for the antivirus definitions. Messages are recorded to the event log indicating whether the update was successful or not.
