Abstract : This survey provides an overview of different cyber moving target techniques, their threat models, and their technical details. A cyber moving target technique refers to any technique that attempts to defend a system and increase the complexity of cyber attacks by making the system less homogeneous, less static, and less deterministic. In this survey, we describe the technical details of each technique, identify the proper threat model associated with the technique, and identify its implementation and operational cost. Moreover, we describe the weaknesses of each technique based on the current proposed attacks and bypassing exploits, and provide possible directions for future research in that area.
