随着科技的发展,网络对人们的影响是巨大的,它改变了我们的生活方式,无论是工作、还是购物甚至娱乐。大量的个人信息充斥着网络,个人信息泄露事件屡见不鲜,网络安全问题也越来越受到人们的关注,网络安全性分析势在必行,目前的网络分析方法中存在攻击图规模庞大、生产算术法效率低等问题,针对这些问题主机攻击图的生产模型和算法被提出,在此方法的基础上,主机安全组的概念及其划分方法应运而生,此方法的原理是通过对网络中的主机划分安全组,从而对网络安全性进行分析,此方法使网络安全情况更为清晰、明确,便于网络管理员对整个网络安全状况的掌握,对提升网络安全性大有裨益。
With the development of science and technology, the impact that the Internet has on people is enormous. It has changed the way we live, whether it is work, shopping or even entertainment. A large number of personal information is flooding the network. Personal information leakage events are not uncommon and network security issues are getting more and more attention. Network security analysis is imperative. At present, the network analysis methods have a large scale of attack graphs, Low efficiency and so on. According to these methods, the production model and algorithm of host attack graph are proposed. On the basis of this method, the concept of host security group and its partitioning method come into being. The principle of this method is that the host Divide the security group to analyze the network security. This method makes the network security situation clearer and more clear, which is convenient for the network administrator to master the security status of the entire network and greatly enhance the network security.
