随着新一代信息技术的发展和“互联网+”的推进,网络安全、信息安全问题变得越来越突出。云计算和大数据的发展,将原先分散的数据都集中起来进行处理,一旦发生数据泄漏,危害程度不可想象。而且,各行各业越来越依赖于信息网络,如果网络被入侵、被控制,将直接危及各行各业的安全,甚至危及国家安全。网络安全,既包含实体物理空间的安全,也包含虚拟数字空间的安全(信息安全也在其内)。网络安全是在对抗状态下的安全,存在着攻防和敌对关系。所以,重要信息领域必须做到没有“后门”。需要说明的是,“后门”与“漏洞”
With the development of a new generation of information technology and the advancement of “Internet +”, the issue of network security and information security has become more and more prominent. Cloud computing and big data development, the original data are scattered together to deal with, in the event of data leakage, the degree of harm can not be imagined. Moreover, all walks of life are increasingly dependent on information networks. If the network is invaded and controlled, it will directly endanger the security of all walks of life and even endanger national security. Cybersecurity includes both the physical and physical security of the physical space, as well as the security of the virtual digital space, which also includes information security. Cybersecurity is security in a confrontational state with offensive and defensive effects and hostile relations. Therefore, important information areas must be done without “back door ”. It should be noted that “backdoor ” and “vulnerability ”
