Security is one of the key concerns for control systems. Tools and simulators for the control system security have attracted a lot of attentions recently, because testing new solutions is a very important work for the control system security studies. In this paper, we firstly analyze the challenges of the security simulations for control system. Then, classification study is done for the existing tools and simulators. The implementation principles the typical simulator examples and security examples are also analyzed. Finally, we compare the important capabilities and characteristic of the tools and simulators, which is valuable to efficient simulations for security studies in control systems.
