Updating Signature Databases Using the CLI

Preparation

This section describes preparations for signature database updates.

Determining Signature Database Update Options

You can determine to download and install an updated signature database or download it only.

Scheduled Update

After scheduled update is configured, the FW automatically downloads signature databases as scheduled.

Immediate Update

You can always update signature databases anytime you want.

Local Update

If the device cannot access the security center, locally update the signature databases.

Version Rollback

When the current signature database is faulty (for example, false positive occurs or system performance is degraded), you can roll back the current signature database to the previous version through version rollbacks.

Version Restoration

If an exception occurs during the update of the signature database, you can restore the signature database to the default version and perform the update again.

Verification and Check

This section describes the verification and check operations after a signature database is updated.
