0引言随着企业网络信息技术的快速发展和广泛应用,社会信息化进程不断加快,生产制造、物流网络、自动化办公系统对信息系统的依赖程度越来越大,因此,保证信息系统的安全稳定运行也越来越重要。如何保证企业网络信息化安全、稳定运行就需要网络规划设计师在设计初始周全的考虑到网络安全所需达到的条件(包括硬件、OSI/RM各层、各种系统操作和应用)。1网络安全、信息安全标准网络安全性标准是指为了规范网络行为,净化网络环境而制 0 Introduction With the rapid development and widespread application of enterprise network information technology, the social informationization process is accelerating. Manufacturing, logistics networks and automated office systems rely more and more on information systems. Therefore, the security and stability of information systems The operation is also more and more important. How to ensure the safety and stability of enterprise network information requires the network planning designer in the initial design to take into account the conditions necessary to achieve network security (including hardware, OSI / RM layers, a variety of system operations and applications). 1 network security, information security standards Network security standards are in order to regulate network behavior, purification of the network environment
