How to set up your FortiWeb : Updating the firmware
 
Updating the firmware
Your new FortiWeb appliance comes with the latest operating system (firmware) when shipped. However, if a new version has been released since your appliance was shipped, you should install it before you continue the installation.
Fortinet periodically releases FortiWeb firmware updates to include enhancements and address issues. After you register your FortiWeb appliance, FortiWeb firmware is available for download at:
https://support.fortinet.com
Installing new firmware can overwrite attack signature packages using the versions of the packages that were current at the time that the firmware image was built. To avoid repeat updates, update the firmware before updating your FortiGuard packages.
New firmware can also introduce new features which you must configure for the first time.
For late-breaking information specific to the firmware release version, see the Release Notes available with that release.
 
In addition to major releases that contain new features, Fortinet releases patch releases that resolve specific issues without containing new features and/or changes to existing features. It is recommended to download and install patch releases as soon as they are available.
 
Before you can download firmware updates for your FortiWeb appliance, you must first register your FortiWeb appliance with Fortinet Technical Support. For details, go to https://support.fortinet.com/ or contact Fortinet Technical Support.
