Rebooting Without Changing the Firmware

To reboot the UTM without changing the firmware:

1.In the Firmware Reboot section of the Firmware screen (see Figure 10-6 on page 10-19), select the active firmware version by clicking the Activation radio button for the firmware that states “active” in the Type column.

2.Select the radio button that corresponds to the firmware version that you want to download onto the UTM.

3.Click Reboot. The UTM reboots. During the reboot process, the Firmware screen remains visible. The reboot process is complete after several minutes when the Test LED on the front panel goes off.

Updating the Scan Signatures and Scan Engine Firmware

To scan and detect viruses, spyware, and other malware threats, the UTM’s scan engine requires two components:

•A pattern file that contains the virus signature files and virus database

•Firmware that functions in conjunction with the pattern file.

Because new virus threats can appear any hour of the day, it is very important to keep both the pattern file and scan engine firmware as current as possible. The UTM can automatically check for updates, as often as every 15 minutes, to ensure that your network protection is current.

To view the current versions and most recent updates of the pattern file and scan engine firmware that your UTM is running:

Select Administration > System Update from the menu. The System Update submenu tabs appear, with the Signatures & Engine screen in view (see Figure 10-7 on page 10-22).
