首先分析目前我国政府计算机网络应用的特点,并结合我国政府网络的结构特点给出网络结构图。由于政府网络结构无法适应政务公开与信息保密的要求,给出一种新型的网络安全结构即边界网络安全结构的结构图,并给出边界网络的详细定义。 First of all, it analyzes the characteristics of the government computer network application in our country at present, and gives the network structure chart according to the structure characteristics of the government network in our country. Because the structure of government network can not meet the requirements of open government and confidentiality of information, a new type of network security structure is given, which is the structure diagram of the boundary network security structure and gives a detailed definition of the boundary network.
