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 know that a specific device on your network is
safe, you can apply Full Trust level to this device. In
addition, you can exclude this specific device from
Intrusion Prevention scan. When you exclude a device
from Intrusion Prevention scan, Norton Internet
Security trusts this device and does not scan any
information that is received from this device. This
improves the network speed of your computer and
helps the trusted device to access your device quickly.
w
You can exclude only full trusted devices that are on
the local subnet.
To exclude a device from Intrusion Prevention scan,
you must ensure that the IP address of the device never
changes. Norton Internet Security uses IP addresses
to identify devices on your home network. If the IP
address of the device changes, Norton Internet Security
cannot identify the trusted device that should be
excluded from Intrusion Prevention scan.
w
You can exclude a trusted device from Intrusion
Prevention scan only if you are sure that the device
does not have any security threats.
When you apply Full Trust to a device and exclude it
from Intrusion Prevention scan, the IP address and
MAC address of the device are added to the Trust
Control.
