Outside Network

Outside networks are also referred to as the external or public networks. The outside area, or untrusted area, is considered to be all devices and networks beyond the direct control of the organization’s administration and security policies. The outside area would typically include the perimeter router, the ISP, the Internet, and all networks attached to it.

While not necessarily the greatest actual threat to many networks, the international scope of the Internet means an organization can face threats from anywhere in the world for reasons that could seem ludicrous at home.
