Power Grid Insecurities Examined
Joe Barr writes "Chris Gulker has taken a long and careful look at the infrastructure of our power grids and has come to some rather unsettling conclusions." A good read that outlines where the current power grid is at, and suggests some paths for the future that may help avoid future blackouts.
Wonderful -- as I read the article, plastered in the center of the page is the ad:
... it frankly scares the hell out of me.
:)
"Microsoft - Big business ambition. Small business resources. Get your FREE 6-month trial now. Windows Small Business Server 2003".
The very fact that the power grid, atm's, so on and so forth -- hell, I worked on the power supply to a embedded PC today for a newspaper printing press that had NT on it
There I'll be sitting there in front of my OS X or Linux box. Can't be too smug I suppose with no power. No telephone. No gas. No cash to buy bread. Hell, the auto-checkout lanes (which I refuse to use on principle) at Jewel are Mickey-MouseSoft based. Certainly no Internet.
For my business' I absolutely refused to allow a Windows server of any type in the datacenter. I still say, "are you nuts?". Yet people still did it. Once again, Bill Gates will get a chance to screw us I guess.
So, when is the next worm due to hit? At least my TiVo will still work...
Says Skroch: "If you have too much security [i.e., no network connections], then the power plant probably won't work."
power plants worked long before the internet was created. no important computer controlling very important things should ever be put on the internet.
"The situation is so bad, experts say, that bored script kiddies could soon be knocking out power stations as easily as they concoct viruses from toolkits available on the Web."
:)
Is it any easier now then it has ever been? It always seemed pretty simple to me. Go down to your local, unmanned, power station and blow it up. Get your buddies and some trucks and knock down some high tension wires. wheeeeee.
Why do people get excited by this? It might be my misanthropic nihilism talking, but shit happens. Every day. Deal with it.
You might lose power, you might lose running water, you might get hit by a bus.
Even if you hole up in a shack to protect yourself from the script kiddies, psychopaths, terrorists and/or government... you're still gonna die!
Have fun!

The power industry needs to be reinvesting profits in infrastructure (powerlines), not stock dividends. The same companies should have been upgrading their command and control systems to prevent chain reaction blackouts. Am I expected to believe the computer systems that manage the cooling rods in the nearest nuke plant are secure?
Seriously consider the economic impact of the grid failure compared to the recent worm problems. Then think about a nasty combination of the two.

It used to be that the utilities were highly regulated entities that had their profit margins basically regulated by the states they were in. They had to provide a given amount of reliability, and rate increases (and occasionally refunds!) were carefully scrutinized as to where the money went. You couldn't raise rates without showing some meaningful improvement that resulted from it.
Then along came degregulation, where the power seller and the power generator became two different things (which makes even less sense than the deregulated-but-shared local phone loop). Utility companies wanted out of the power generation arena -- too expensive, too many regulations, it was better to be in the new "commodity" end of the business, arbitraging power. So they split themselves into trading companies and generation companies, taking all the cash into the trading companies, who were deregulated and could spend it freely.
And then 10 years later, Enron and the whole deregulated power "market" has collapsed, and we wonder why we're 15-20 years behind the curve on power grid and other key infrastructure elements. All the money got spent on speculating in the newly deregulated power markets, and its all gone.
Nobody really pays any less for electricity, I don't have a bunch of people knocking on my door offering me their window electricity or biodiesel electricity or their pig shit methane electricity for that matter.
I only have the sheepish looking local utility trying to explain to me how they're trying to fix the power infrastructure built in the 1970s with the cash made in the 1980s which was spent in the 1990s on the promise of getting rich in the new millenium. When in fact, they actually need me to pay the prices of the next millenium for the service delivered in the 1990s, and, oh, would I please only use as much power as I did in the 1970s?
Haha, what grand scheme of things?
Humanity isn't trying to reach for the pinnacle of its capabilities, it's trying to find more comfortable ways to live and fuck.
People want more power so they can do more cool shit, and do it cheaper. That's it.
Leading in all forms of waste and corruption. Nice example for the future. Here's a primer on human nature -- more of anything doesn't make people use it smarter, it makes them squander it faster. Western society is terrible for this.
Your post is an attempt to be modded insightful by using big words to sound profound. Nothing you've said makes any sense.

We're starting to see a few problems appear more than once, though.
-
Telecom vulnerability to power failure.
-
"Non-critical" systems that aren't.
-
Cross-connection between business systems and control systems
That's a more realistic picture of what's going on.AT&T was determinedly independent of the power grid in the days of Ma Bell. Every central office ran on 48VDC storage batteries, with backup generators. The backup generators were started once a week, and run for several hours once a month. Once a year, each central office ran for 24 hours cut off from external power.
That was a long time ago, back when AT&T was a regulated monopoly common carrier. In the new, competitive era, that depth of backup can no longer be assumed. Carriers in trouble (WorldCom, Adelphia) tend to cut things like that.
The details aren't in yet, but it's beginning to look as if, during the recent big blackout, some comm links went down very early, so that the fault information that's supposed to divide the grid cleanly into islands didn't get through. Once all the logs have been correlated, it will be clear what happened.
A few weeks ago, CSX, the railroad, had a shutdown due to a virus. Railroad signalling has used "code lines" for decades, for remote control of switches and signals. These are basically serial links over which commands and responses are sent. The safety logic is local, but if you lose a code line, the dispatcher can't throw switches and route trains.
The tendency to centralize train control has resulted in a need to transmit code line signals hundreds or thousands of miles. So they tend to be multiplexed over telecom-like facilities. CSX apparently routed theirs over their in-house general purpose network. The routers in that network were managed by a network management system that ran on Windows. When the Windows machines went down, system management of the routers stopped, and, after a while, this apparently took some key routers down. So a "non-critical" system actually stopped train movements.
It's really convenient to be able to see what the plant is doing from your desktop. Order processing is more efficient if the sales network connects to the factory network. Energy traders need to be able to see what the power plants are doing, and give directions to power dispatchers. These things all create vulnerable paths.
