Updating the Digital Vaccine (Filters)

When new types of network attack are discovered, or when detection methods for existing threats improve, the Digital Vaccine team at the Threat Management Center (TMC) creates and releases new filters to add to your filter database. These filters are released as Digital Vaccine (DV) packages.

When a new DV package is available for download, the TMC team sends notifications to existing customers. You have two options to update the DV on your device:

•Configure the Auto DV option on your device so that the device can check for new DV packages and automatically update the device as necessary.

If AutoDV is configured, the device automatically checks the DV version when you open the Auto DV Configuration page. The status is listed in the Auto Update section. To perform an update immediately, click Update Now.

•Manually download and install the DV package.

You can manually download the most current DV from the Threat Management Center, and then manually install the DV update.

Note You cannot rollback to a previous Digital Vaccine version. If you want to use a previous version of a Digital Vaccine, select an older version of the Digital Vaccine package from the TMC.

To make sure the device has enough disk space, you may need to delete previously installed software images from the Update page. For details, see “Delete a previously installed TOS software version” on page 221.
