Firewall Management

February 15, 2024

ID 202310

The operating system firewall protects personal data that is stored on the user's device. The firewall blocks most threats to the operating system when the device is connected to the Internet or a LAN. Firewall Management detects all network connections by the user's device and provides a list of IP addresses, as well as an indication of the default network connection's status.

The Firewall Management component filters all network activity according to the network packet rules. Configuring network packet rules lets you specify the desired level of the device protection, from blocking Internet access for all applications to allowing unlimited access.

It is recommended to disable other operating system firewall management tools before enabling the Firewall Management component.
