Power grid security

Five Reasons The U.S. Power Grid Is Overdue For A Cyber Catastrophe


With 450,000 miles of high-voltage transmission lines, the U.S. electrical grid is intrinsically vulnerable to upset from severe weather, mechanical failures and wandering wildlife.  But cyber attacks could be the danger that ultimately becomes the grid's undoing.
