Internet Security/Architecture Task Force Report. Defining the Edge of the Internet

摘要

During the President's National Security Telecommunications Advisory Committee (NSTAC) XXV Principals' Meeting of March 12-13, 2002, concern was expressed over the ability to protect the 'edges' of the Internet against attack or exploitation. To defend the edge, it is first necessary to define the edge and to understand the relevant perimeter that is needed to protect the Nation's critical infrastructures. However, there is no universal definition for the edge of the Internet. Many consider the Internet borderless or without any edge. Some consider the edge of the Internet to be the end-user terminal level-the millions and millions of desktops in homes and small businesses around the Nation and around the world-while others believe it to be the point at which an Internet service provider (ISP) interconnects with the backbone network. Consequently, the task force concluded that to protect the critical infrastructure of the United States, the focus should involve all elements of the Internet rather than attempt to focus security efforts at the edge. Security practices throughout the Internet must be as fluid and dynamic as the Internet itself.
