4 Select Refresh.
The FortiGate unit tests its connection to the FDN. The test results are displayed
at the top of the System Update page.
To update antivirus and attack definitions
1 Go to System > Maintenance > FortiGuard Center.
2 Select Update Now to update the antivirus and attack definitions.
If the connection to the FDN or override server 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 Update Center page lists
new version information for antivirus definitions and attack definitions. The System
Status page also displays new dates and version numbers for antivirus, attack and
IPS definitions. Messages are recorded to the event log indicating whether the
update was successful or not.
Note: Updating antivirus and attack definitions can cause a very short disruption in traffic
currently being scanned while the FortiGate unit applies the new signature database. To
minimize this possibility, schedule updates for times of light traffic.
To enable scheduled updates
1 Go to System > Maintenance > FortiGuard Center.
2 Select the Scheduled Update check box.
3 Select one of the following to check for and download updates.
Every
Daily
Weekly
Once every 1 to 23 hours. Select the number of hours and minutes between
each update request.
Once a day. You can specify the time of day to check for updates.
Once a week. You can specify the day of the week and the time of day to
check for updates.
4 Select Apply.
The FortiGate unit starts the next scheduled update according to the new update
schedule.
Whenever the FortiGate unit runs a scheduled update, the event is recorded in the
FortiGate event log.
To add an override server
If you cannot connect to the FDN, or if your organization provides antivirus and
attack updates using their own FortiGuard server, you can use the following
procedure to add the IP address of an override FortiGuard server.
1 Go to System > Maintenance > FortiGuard Center.
2 Select the Use override server address check box.
3 Type the fully qualified domain name or IP address of a FortiGuard server.
