Description
On the Log > Name Resolution page, set
it to DNS then NetBIOS and click the
Apply button in the upper-right-hand part
of the screen to save and activate the
change. This lets the appliance apply more
a "friendly" name to the IP address in the
log, including the NetBIOS names of
systems on the LAN, which is easier than
using a non-fixed IP address. Do not use
this setting if you are using DNS servers
supplied by your ISP.
Store known-good preferences and
firmware in a safe place that is accessible in
the event of problems with the appliance,
and verify the appliance is always under a
valid service and software support contract.
Disaster recovery can be fairly painless if
you follow these policies.
Other measures are irrelevant if you do not
limit physical access to the security
appliance itself, as it can be easily reset and
illegally accessed if an intruder can get to
the security appliance.
