In this article Ira Winkler discusses how meter vulnerabilities are changing his mind about the potential for a wide-spread attack to the nation’s electrical infrastructure.

The grid is unique in that most of the grid’s assets are publicly accessible. With that in mind, good security practitioners will ASSUME that public assets like meters will be compromised.

The trick is how to build a resilient smart grid even when most of the assets are subject to compromise. The key is to protect sensitive upstream assets from compromised endpoints. By designing a grid network to enforce the security concept of least privilege, we can go a long way to building a resilient grid. This would include things like

These kinds of safeguards apply to both the Automated Metering Infrastructure, as well as for Distribution Automation (e.g., pole-top) devices.

While securing the grid on an end-to-end basis is a significant technical challenge, there are standards and best practices that can be applied to reduce vulnerabilities.
