Cybersecurity: Challenges in Securing the Electricity Grid

The electric power industry is increasingly incorporating information technology (IT) systems and networks into its existing infrastructure (e.g., electricity networks, including power lines and customer meters). This use of IT can provide many benefits, such as greater efficiency and lower costs to consumers. However, this increased reliance on IT systems and networks also exposes the grid to cybersecurity vulnerabilities, which can be exploited by attackers. Moreover, GAO has identified protecting systems supporting our nation’s critical infrastructure (which includes the electricity grid) as a governmentwide high-risk area.
