Product manual

Scanning every request from all the devices that access
your computer increases the scan time which slows
down the network speed of your computer.
If you are sure that a device on your network is safe,
you can change the trust level of the device to Full
Trust. You can configure the trust level of a device
using the Network Security Map. You can exclude these
trusted devices from Intrusion Prevention scan.
Excluding Full Trust devices from the Intrusion
Prevention scan saves the scan time and improves the
network speed of your computer. When you exclude a
device that is set to Full Trust, Norton Internet Security
does not scan any information that is received from
this device. The Full Trust devices that are excluded
from Intrusion Prevention scan are added to Intrusion
Prevention exclusion list.
When a device on your network attempts to infect your
computer, AutoBlock stops all access requests from
this device. If you add this device to the Intrusion
Prevention exclusion list, Norton Internet Security
removes the device from the exclusion list.
w
Ensure that the IP address of the devices that are added
to Intrusion Prevention exclusion list never changes.
If you find that any of the devices that you excluded
from the Intrusion Prevention scan is infected, you can
purge the saved exclusion list. When you purge the
exclusion list, Norton Internet Security removes all the
IPS excluded devices from the exclusion list.
Removing all devices from Intrusion Prevention
exclusion list
If you are sure that a device on your network is safe,
you can 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. Excluding Full Trust devices
from Intrusion Prevention scan saves the scan time
and improves the network speed of your computer.
