The electrical power grid is in the midst of a breathtaking transformation into the “Smart Grid.” A key element is development of the Advanced Metering Infrastructure (AMI), which is changing the way utilities interact with smart meters at customer sites. However, with the technology come new risks of cyber-attacks that could exploit vulnerabilities in different parts of the communication layers, and potentially affect significant portions of the power grid. In this talk, I will discuss the progress of Smart Grid AMI system development and the security research projects that are working to protect the AMI against various cyber threats in Korea. The first part of the talk will be devoted to an overview of the Korea Smart Grid AMI system; I will present its key components and network models to be deployed in the field in the near future. In the second part of the talk, I will address more specific security issues and vulnerabilities in Smart Grid systems in relation to our test-beds and several research projects to ensure the security of the systems based on the different research viewpoints from existing security solutions. The last part of the talk will discuss ways to detect DDoS attack traffic in smart meters, DCUs (Data Concentration Units), and AMI headends using an efficient distributed traffic monitoring architecture in the AMI networks, a result of international collaborative research conducted by NSRI (the National Security Research Institute) and ITI (the Information Trust Institute). The talk will end with a discussion of the experimental results of our developments in the Smart Grid test-bed.
