Intrusion Prevention exclusion list

The Intrusion Prevention System in your Norton product scans all the network traffic that enters and exits your computer. When a device on your network requests access to your computer, Intrusion Prevention scans this request to ensure that it is not a virus attack. If the information matches an attack signature, Intrusion Prevention blocks the traffic from the suspicious device and protects your computer. 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 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.

When a device on your network attempts to infect your computer, AutoBlock stops all access requests from this device.

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

Thank you!
