Siemens is the first company in the world to have received certification for a grid automation solution based on the most comprehensive international cybersecurity standard. TÜV Süd, a global testing, certification, inspection and training provider based in Germany, awarded the certification, which is based on the IEC 62443 standard, to a security framework that Siemens developed for automated transformer substations.
Power grids are an essential infrastructure that must be protected against hacker attacks. As electricity generation becomes increasingly decentralized, thus also increasing grid complexity, automation is growing in importance for smart grids that are networked by means of communication technology. Many solutions are already available today, and most high-voltage and medium-voltage systems have been digitized. A relatively new development is the opening of previously closed communication networks to the Internet through the incorporation of new devices and applications. As a result, security measures against cyberattacks have to be continuously adapted to new dangers.
