Abstract
As a critical infrastructure, smart substation is one of typical industrial control systems, whose information security evaluation has been one of the most pressing issues. As much as a system is critical, chances of attack from outer or from inner are more. The attack could be on hardware device, software solution and on integrated database with in substation. This paper introduces some experiences from the practices of smart substation's information security testing in Jiangsu Electric Power Company Research Institute (JSEPRI). We first give information security threats faced by ICS in the filed of smart grid, analyze the requirements of the information security testing system construction, proposes a method to build a testbed for substations, and describes several key technologies involved in the testbed.
