Network Boundary and Protection

摘要

The exposure of PRISM reminds us of network sovereignty. There are two problems about network sovereignty-network boundary partition and protection. These two problems are discussed in this paper. A method of multidimensional network boundary partition is proposed based on comprehensive analysis of existing schemes. And network boundary protection is studied based on standard rules of cyber warfare. Characteristic of network boundary protection technique is analyzed and methods are proposed about how to construct network boundary protection.
