A smart grid is a grid system that integrates power generation, transmission, distribution, and users through information and automation technology. In other words, it combines IT (Information Technology) and OT (Operational Technology) to be used in the power system which includes the power generation, transmission, distribution and users. However, the power system is an important infrastructure, and it will face considerable risks after informatization and automation. Therefore, many expert groups from various countries are actively involved in the drafting of smart grid-related cyber security standards. The content of these standards is complex, making it difficult for relevant personnel to find the required information security standards. Firstly, we will analyze many related information security standards for smart grids and industrial automation, such as IEC 62443, IEC 62351, NISTIR 7628 and ISO 27001 in this paper. Secondly, we will classify and compare the differences between the security technologies and threats of these standards. Finally, we will use the five core functions of the Cybersecurity Framework (CSF) to category these standards and then provide an information security protection guideline when people want to set up or design the smart grids.
