A software firewall that may be configured using rules specified for types of network interfaces rather than individual network interfaces. The network types may be specified with type identifiers that have a readily understandable meaning to a user, facilitating ease of configuring the firewall. The network types could include, for example, wired, wireless and remote access. A rule specified based on a network type can be implemented for network interfaces of that network type. The implementation may be performed automatically and may be updated based on network location awareness information.
