ZDNet: Our fancy Internet infrastructure operates on a wire and a prayer

From ZDNet:

What’s truly scary is that we’re not just talking about the Internet here. The electric grid is vulnerable. Our transportation grid is vulnerable. Our infrastructure in the U.S. is a big sitting duck. The grid and the Internet are top of mind today, but I’m reminded of the overall infrastructure vulnerability every trip into Penn Station. Every once in a while you’ll see heavily armed police with their K-9 dogs in Penn Station’s lobby. It’s a common sight. However, if you really wanted to bring down the train station and subway it’s nothing a stray backpack couldn’t take care of.
