IEC 62351

Standards for Security Power System Communications


Defending today’s power systems is challenging because they typically use communication protocols optimized for bandwidth and efficiency, with zero or simple security protections. Furthermore, many grids have received little to no security enhancements post deployment.

To help counter this problem, in the early 2000s IEC Technical Committee 57, a group devoted to power system management standards, started working on how to make power grids secure-by-design. Working Group 15 (WG15) was formed to evaluate the requirements from a technology perspective, and define a standard way to implement them.

Nozomi Networks Co-founder and CTO, Moreno Carullo, has been a member of WG15 since 2015 and has have contributed to the development of the standards, particularly sections related to power system monitoring.

At Black Hat USA 2019, the team presented a demonstration of how the IEC 62351 standards could be used for monitoring industrial networks. They demonstrated how four types of hard-to-detect attacks are readily identified. This new approach to asset health monitoring significantly enhances threat detection and power grid cyber resiliency.

Advances in Cyber Security for Electric Utilities: WG15 & Black Hat

As a passionate champion for secure-by-design power grid systems, I’ve been part of WG15, the group defining IEC 62351 standards to enable such systems, for years.

If you’d like to learn about the future of cyber security for electric utilities, I urge you to read this article. It also provides a sneak peek into our related (and groundbreaking!) talk about power system security at Black Hat USA 2019.

IEC 62351 Standards for Securing Power System Communications

To help counter the growing concern about cyberattacks aiming to disrupt power systems, industrial experts have been working together in WG15. This group, part of IEC, is defining the standards known as IEC 62351, for secure-by-design power grids.

As a member of WG 15 since 2015, I thought it might be helpful to inform you about these standards and provide an update on their status.

Advancing IEC Standards for Power Grid Cyber Security

Last week Nozomi Networks had the privilege of hosting the first WG15 meeting of 2017. This group is responsible for establishing end-to-end cyber security standards for the world’s power system communication protocols. Read on to learn more about WG15 and how we advanced standards for encrypted communications for the power grids of the future.
