The FBI and the US Department of Homeland Security (DHS) has begun
warning companies that operate elements of the country's critical
infrastructure about cyber threats to the power grid. The program
started after the December attacks against power companies in Ukraine.
The campaign includes webinars and briefings about the attacks and
offers suggestions for mitigating risk and bolstering cybersecurity.
