Setting AV service level
FortiADC's AV service relies on the system's AV engine and signature databases. The AV engine is upgraded whenever new functions are added. The Updated daemon is responsible for updating the AV engine and the signature databases.
The system offers three types of AV signature databases, namely, Normal, Extended, and Extreme. They represent different levels of AV services. In order for FortiADC to provide you with the level of AV service that you desire, you must choose the right signature database.
Configure AV service level from the GUI
To choose a signature database from the GUI,
- From the navigation bar, click Network Security > Anti Virus.
- Click the Settings tab.
- Select a Default DB setting:
Settings Description Normal The regular virus database, which includes “In the Wild” viruses and most commonly seen viruses on the network. It provides regular protection.
Extended The extended virus database, which includes both “In the Wild” viruses and a large collection of zoo viruses that are no longer seen in recent virus studies. It provides enhanced security protection.
Extreme The extreme virus database, which includes both “In the Wild” viruses and all known zoo viruses that are no longer seen in recent virus studies. It provides the highest level of security protection.
- Specify the Ramdisk size in GB. The default is 0 GB. Valid values range from 0 to 12 GB. Please ensure to enlarge the RAM disk size to scan large files.
Note: When the changes to the RAM disk configuration is committed, you will be prompted to restart the device for the configuration to take effect. - Click Save.
Configure AV service level from the Console
To set the default signature database from Console, execute the following command:
config security antivirus settings
set default-db {normal | extended | extreme}
set ramdisk-size <integer>
end
