"The Department of Energy (DOE) is the lead agency for the protection of electric power, oil, and natural gas infrastructure--cooperating with the Department of Homeland Security, the lead agency for pipelines. DOE's cybersecurity activities are led by its Office of Electricity Delivery and Energy Reliability (OE) and structured around three areas: (1) cybersecurity preparedness, (2) cyber incident response and recovery, and (3) research, development, and demonstration. Although nominally applicable to energy delivery systems across the electric power, oil and natural gas, and pipeline sectors, OE's cybersecurity activities to date appear to have been focused primarily on the grid. Publicly available examples of DOE-supported activities specifically focused on pipeline cybersecurity are limited. Rather, pipeline cybersecurity efforts appear to be included as part of broader national cybersecurity efforts."
