Securing the Life Cycle in the Smart Grid

By: Kris Ardis

Abstract: Investment in smart meters and smart grid end equipment continues to grow worldwide as countries try to make their electric delivery systems more efficient. However, as critical as the electric delivery infrastructure is, it is normally not secured and thus subject to attack. This article describes the concept of life-cycle security—the idea that embedded equipment in the smart grid must have security designed into the entire life of the product, even back to the contract manufacturer. We also talk about how life-cycle security applies to embedded equipment in the smart grid. Potential threats are discussed, as are potential solutions to mitigate the risks posed by those threats.
