Abstract

Ongoing communication technology integration into the national energy infrastructure increases near realtime information exchange contributing to a smarter grid. The national energy infrastructure's incremental evolution into a smarter grid simultaneously provides opportunities for efficiency, reliability, and security improvements while exposing existing security failures. We examine current programmable logic control (PLC) security vulnerability exploitations and offer a layered cyber defense strategy as an information security solution to address the dynamic and unique challenge of securing the energy grid.
