Abstract

While Moving Target Defenses (MTDs) have been increasingly recognized as a promising direction for cyber security, quantifying the effects of MTDs remains mostly an open problem. Each MTD has its own set of advantages and disadvantages. No single MTD provides an effective defense against the entire range of possible threats. One of the challenges facing MTD quantification efforts is predicting the cumulative effect of implementing multiple MTDs. We present a scenario where two MTDs are deployed in an experimental testbed created to model a realistic use case. This is followed by a probabilistic analysis of the effectiveness of both MTDs against a multi-step attack, along with the MTDs' impact on availability to legitimate users. Our work is essential to providing decision makers with the knowledge to make informed choices regarding cyber defense.
同步移动目标防御分析
虽然移动目标防御(MTDs)越来越被认为是网络安全的一个有前途的方向,但量化MTDs的影响仍然是一个悬而未决的问题。每个MTD都有自己的优点和缺点。没有单一的MTD能够有效地防御所有可能的威胁。MTD量化工作面临的挑战之一是预测实施多个MTD的累积效应。我们给出了一个场景,其中两个mtd部署在一个实验性测试平台中,该测试平台是为了模拟一个实际的用例而创建的。接下来是对两个mtd对抗多步骤攻击的有效性的概率分析,以及mtd对合法用户可用性的影响。我们的工作对于为决策者提供在网络防御方面做出明智选择的知识至关重要。
