Abstract

Moving target systems can help defenders limit the utility of reconnaissance for adversaries, hindering the effectiveness of attacks. While moving target systems are a topic of robust research, we find that prior work in network-based moving target defenses has limitations in either scalability or the ability to protect public servers accessible to unmodified clients. In this work, we present a new moving target defense using software-defined networking (SDN) that can service unmodified clients while avoiding scalability limitations. We then evaluate this approach according to seven moving-target properties and evaluate its performance. We find that the approach achieves its security goals while introducing low overheads.
SDN Shuffle:使用基于主机的软件定义网络创建移动目标防御
移动目标系统可以帮助防御者限制敌方侦察的效用,阻碍攻击的有效性。虽然移动目标系统是一个强有力的研究课题,但我们发现,先前基于网络的移动目标防御工作在可扩展性或保护未修改客户端可访问的公共服务器的能力方面存在局限性。在这项工作中,我们提出了一种新的移动目标防御,使用软件定义网络(SDN),可以为未修改的客户端提供服务,同时避免可扩展性限制。然后根据7个运动目标属性对该方法进行了评价,并对其性能进行了评价。我们发现该方法在引入低开销的同时实现了其安全目标。
