How do application control signatures update on a FortiGate device?

FortiGate devices rely on the FortiGuard service to receive continuous updates for various security features, including application control signatures, ensuring the device has the most current information to identify and control applications.

While firmware upgrades might include updated signatures as part of a new OS version, this is not the primary or continuous method for signature updates; FortiGuard provides frequent, independent updates.

Application Control auto-learning is a feature to identify unknown applications and suggest policies, but it does not update the signature database itself.

Signatures are not hard-coded and are regularly updated to protect against new and evolving applications.
