Security holes in power grid have federal officials scrambling

Security holes in power grid have federal officials scrambling - latimes.com:
WASHINGTON — Adam Crain assumed that tapping into the computer networks used by power companies to keep electricity zipping through transmission lines would be nearly impossible in these days of heightened vigilance over cybersecurity.
When he discovered how wrong he was, his work sent Homeland Security Department officials into a scramble.
Crain, the owner of a small tech firm in Raleigh, N.C., along with a research partner, found penetrating transmission systems used by dozens of utilities to be startlingly easy. 

After they shared their discovery with beleaguered utility security officials, the Homeland Security Department began sending alerts to power grid operators, advising them to upgrade their software.
The alerts haven't stopped because Crain keeps finding new security holes he can exploit.
"There are a lot of people going through various stages of denial" about how easily terrorists could disrupt the power grid, he said. 

"If I could write a tool that does this, you can be sure a nation state or someone with more resources could."
