If you are sure that a device on your network is safe,
you use the Edit Device Trust Level window to change
the trust level of the device to Full Trust. You can then
select the Exclude from IPS scanning option to exclude
these trusted devices from Intrusion Prevention scan.
Intrusion Prevention relies on an extensive list of
attack signatures to detect and block suspicious
network activity. Norton Internet Security runs
LiveUpdate automatically to keep your list of attack
signatures up to date. If you do not use Automatic
LiveUpdate, you should manually run LiveUpdate once
a week.
