Learn more about 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 configure the trust level of a device using the Device Trust under Network Settings. 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, your Norton product 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.

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, your Norton product removes all the IPS excluded devices from the exclusion list.

You can purge the saved exclusion list under the following circumstances:

• Any of the devices that you excluded from Intrusion Prevention scan is infected.

• Any of the devices that you excluded from Intrusion Prevention scan attempts to infect your computer.

• Your home network is infected.
