| 摘 要： | 针对当前网络安全态势感知方法侧重安全信息而轻视网络性能参数的不足,提出一种基于性能参数修正的网络安全态势量化算法。首先对网络的服务和主机态势进行逐级量化,利用性能信息修正主机安全态势,进而依据主机权重信息计算网络的整体安全态势值。通过构建网络实例对算法进行实验,验证了该算法的有效性和可行性。 |

| Abstract: | The existing network security situation awareness method focuses on security information and lacks of network performance parameters, for solving these shortages, a quantitative algorithm of network security situation awareness based on performance parameters correction is introduced. At first, the security situation value of services and hosts are quantized in proper order. Then, the hosts security situation value need to be corrected by using performance parameters. Finally, the security situation value of local networks can be calculated by the weight of hosts. By constructing the network environment, a simulated experiment is performed, and the results prove that the algorithm is effective and feasible. |
| Keywords: | network security situation awareness performance parameters correction weight quantitative |
