基于隐马尔可夫模型的网络安全态势评估
NETWORK SECURITY SITUATION ASSESSMENT BASED ON HIDDEN MARKOV MODEL
摘要
Abstract
In order to estimate real-time security situation of the network , we build a quantified network security situation assessment mod-el aiming at the limitations of existing method that the evaluating objects are restricted to services hosts but not takes both the attack and de -fense information into consideration .The model has four levels from top to bottom , including the network system , equipments , equipment nodes and attacks , covers all resources in the network system , and the assessment strategy of “from part to whole” is adopted.The security condition of the equipments node is evaluated from both aspects of attacking threat and self risk based on hidden Markov model , and the whole security situation of network system is educed from weighted summarisation finally .Experimental results show that the method can well depict the situation trend of the network system .关键词
