FortiSIEM OS Update Procedure
FortiSIEM runs on Rocky Linux. This document provides steps for customers to upgrade their version of Rocky Linux, without upgrading FortiSIEM.
FortiSIEM maintains its own Rocky Linux repository.
-
os-pkgs-cdn.fortisiem.fortinet.com
-
os-pkgs-r8.fortisiem.fortinet.com
When Rocky Linux publishes an OS update, an announcement is made via Rocky Linux 8 Changelog. The FortiSIEM engineering team review the Rocky Linux 8 Changelog on a weekly basis.
Once a new update is available, the FortiSIEM engineering team first tests these updates for stability and upgradability from older OS versions. After confirming that the update is safe to deploy, FortiSIEM updates its Rocky Linux repository from official Rocky Linux 8 mirror servers.
Upon notification of a critical Rocky Linux vulnerability, the FortiSIEM engineering team review the update out of band of the weekly Changelog review. If deemed necessary, the FortiSIEM team will update the FortiSIEM Rocky Linux repositories.
Customers can then upgrade their FortiSIEM OS without necessarily upgrading the FortiSIEM application.
To upgrade FortiSIEM OS without going to the latest FortiSIEM release, take follow the steps.
Notes:
-
For FortiSIEM OS upgrade, you will need port 443 access to:
-
os-pkgs-cdn.fortisiem.fortinet.com
-

You can upgrade from FortiSIEM 6.4.1, 6.4.2, 6.5.0, 6.5.1, 6.6.0, 6.6.1, 6.6.2, 6.6.3 and 6.7.0+. If you are running versions older than 6.4.1, then first upgrade FortiSIEM to 6.4.1 and then perform OS upgrade.
-
If you are running FortiSIEM in an offline mode without internet connection, then you need to set up an offline repository server instead of directly using the Fortinet OS repo. Check the latest Offline Upgrade guide in the FortiSIEM Documents Library for more information.
