Network definitions serve as filter criteria in network protection rules.
Network Addresses monitor network connections between an external source and a managed computer. The definition is a single address, a range, or a subnet. You can include and exclude defined network addresses in network communication protection rules.
Network Port definitions in network communication protection rules allow you to exclude specific services as defined by their network ports. A list of common services and their ports is built in. You can edit the items on the list, or create your own definitions.
Network Share definitions specify shared network folders in network share protection rules. You can include or exclude defined shares.
