移动目标防御技术研究

Analysis on Moving Target Defense Technique

移动目标防御(MTD)技术是近年来出现的网络安全领域的革命性技术,现已取得了一定的研究进展,反映了未来网络防御技术的发展趋势。该技术通过不断变化的网络配置增加攻击者的攻击难度及攻击成本,减小与防御者之间的不对称性,有效地保护网络安全,将从本质上彻底改变网络安全防御模式。在分析目前的计算机网络防御方法的基础上,对MTD技术的概念及系统组成和最新研究进展进行了论述。

Moving target defense（MTD） emerging recently is a revolutionary technique in network security area,some development progresses have been obtained currently.It reflects the development trend of American military network defense techniques in the future. It effectively protects networks through increasing attack difficulty for the attackers by constantly variable network configurations, and will thoroughly change the network security defense mode. On basis of analyzing current computer network defense approaches, the concept and system composition,and updated development results of MTD technique are presented.
