To increase the convenience in daily life activities, the Internet of Things (IoT) technology has been developed and used; it can achieve a hyper-connected society by connecting various devices and systems through the Internet. In building an IoT environment, the moving target defense (MTD) strategy is used as a method to construct an active defense strategy for a mission-critical system. However, there is a lack of indicators that can easily identify the various properties of the MTD strategy and enable in constructing and establishing a new MTD strategy-based protection plan. To solve this problem, in this paper, we survey various MTD strategy research results and analyze the research that has been conducted to derive the various properties of the three perspectives in the MTD strategy (When to move, What to move, How to move). In addition, based on the various derived properties, we propose a graph that can easily identify the various research results that appear. Additionally, it shows that the combination of various properties can be used as an indicator to understand the research direction of a new protection strategy research based on the software-defined MTD strategy for IoT device protection.
