0引言在全球范畴内,计算机网络正被广泛接纳,它紧密关联着多科目技术、平日常规管理、系统特有的维护。从现有状态看,防火墙从初始的偏低层级延展至更高层级,安全水准升高。它能过滤信息,也增设了搭配着的安全管控流程,供应专门服务。布设防火墙时,要考量网络表现出来的总状态,明晰IP地址。未来时段内,仍应经由探究来完善这一技术,创设更适宜的应用路径。1探析安全内涵1.1关于信息互通 0 Introduction In the global context, computer network is widely accepted, it is closely related to multi-subject technology, weekday management, system-specific maintenance. From the current state, the firewall extends from the initial low level to a higher level, and the security level is higher. It can filter information, but also added with the security control process, the supply of specialized services. When laying out the firewall, we must consider the overall network performance, clear IP address. In the coming period, this technology should still be consummated through exploration to create a more suitable application path. 1 Analysis of security implications 1.1 on the exchange of information
