基于卡尔曼算法的网络安全态势预测方法分析

摘要

In recent years,the network information technology has rapid development,and is gradually entered into the de⁃velopment of all trades and professions,which changes people′s production mode and life style,and brings great convenience for people′s basic necessities. The network can provide great convenience for people while existing large hidden danger,which threatens people′s privacy and network security. It is necessary to analyze and predict the network security situation,and then find out a reasonable algorithm to analyze the situation. The scientific model of network security situation was established to pro⁃vide effective information for the network managers to make the security decisions,and improve the network security degree. The Kalman algorithm is used to analyze the prediction method of network security situation. The superiority of the algorithm is analyzed.%近几年，网络信息技术发展迅速，并逐渐进入社会各行各业的发展中，不仅改变着人们的生产方式，同时也改变了人们的生活方式，给人们衣食住行带来了很大的方便。但是应该看到网络在给人们带来极大便利的同时也存在较大的安全隐患，威胁人们的隐私和网络安全。所以必须要对网络安全态势进行分析和预测，找到一种合理的算法进行态势分析，建立科学的网络安全态势模型，为网络管理者做出安全防护的决策提供有效信息，提高网络安全度。这里主要利用卡尔曼算法进行网络安全态势预测方法的分析，并分析该算法的优越性。
