The Economist has a look at the state of America's infrastructure - America's transport infrastructure: Life in the slow lane.

America, despite its wealth and strength, often seems to be falling apart. American cities have suffered a rash of recent infrastructure calamities, from the failure of the New Orleans levees to the collapse of a highway bridge in Minneapolis, to a fatal crash on Washington, DC’s (generally impressive) metro system. But just as striking are the common shortcomings. America’s civil engineers routinely give its transport structures poor marks, rating roads, rails and bridges as deficient or functionally obsolete. And according to a World Economic Forum study America’s infrastructure has got worse, by comparison with other countries, over the past decade. In the WEF 2010 league table America now ranks 23rd for overall infrastructure quality, between Spain and Chile. Its roads, railways, ports and air-transport infrastructure are all judged mediocre against networks in northern Europe.

America is known for its huge highways, but with few exceptions (London among them) American traffic congestion is worse than western Europe’s. Average delays in America’s largest cities exceed those in cities like Berlin and Copenhagen. Americans spend considerably more time commuting than most Europeans; only Hungarians and Romanians take longer to get to work (see chart 1). More time on lower quality roads also makes for a deadlier transport network. With some 15 deaths a year for every 100,000 people, the road fatality rate in America is 60% above the OECD average; 33,000 Americans were killed on roads in 2010.

There is little relief for the weary traveller on America’s rail system. The absence of true high-speed rail is a continuing embarrassment to the nation’s rail enthusiasts. America’s fastest and most reliable line, the north-eastern corridor’s Acela, averages a sluggish 70 miles per hour between Washington and Boston. The French TGV from Paris to Lyon, by contrast, runs at an average speed of 140mph. America’s trains aren’t just slow; they are late. Where European passenger service is punctual around 90% of the time, American short-haul service achieves just a 77% punctuality rating. Long-distance trains are even less reliable.

Air travel is no relief. Airport delays at hubs like Chicago and Atlanta are as bad as any in Europe. Air travel still relies on a ground-based tracking system from the 1950s, which forces planes to use inefficient routes in order to stay in contact with controllers. The system’s imprecision obliges controllers to keep more distance between air traffic, reducing the number of planes that can fly in the available space. And this is not the system’s only bottleneck. Overbooked airports frequently lead to runway congestion, forcing travellers to spend long hours stranded on the tarmac while they wait to take off or disembark. Meanwhile, security and immigration procedures in American airports drive travellers to the brink of rebellion.

And worse looms. The country’s already stressed infrastructure must handle a growing load in decades to come, thanks to America’s distinctly non-European demographics. The Census Bureau expects the population to grow by 40% over the next four decades, equivalent to the entire population of Japan.

All this is puzzling. America’s economy remains the world’s largest; its citizens are among the world’s richest. The government is not constitutionally opposed to grand public works. The country stitched its continental expanse together through two centuries of ambitious earthmoving. Almost from the beginning of the republic the federal government encouraged the building of critical canals and roadways. In the 19th century Congress provided funding for a transcontinental railway linking the east and west coasts. And between 1956 and 1992 America constructed the interstate system, among the largest public-works projects in history, which criss-crossed the continent with nearly 50,000 miles of motorways.

But modern America is stingier. Total public spending on transport and water infrastructure has fallen steadily since the 1960s and now stands at 2.4% of GDP. Europe, by contrast, invests 5% of GDP in its infrastructure, while China is racing into the future at 9%. America’s spending as a share of GDP has not come close to European levels for over 50 years. Over that time funds for both capital investments and operations and maintenance have steadily dropped.

Wired has a look at efforts to prevent hacking of the electrical grid in the US - Hacking the Electric Grid? You and What Army ?.

Grid-hacking is back in the news, with the unveiling of “Perfect Citizen,” the National Security Agency’s creepily named effort to protect the networks of electrical companies and nuclear power plants.

People have claimed in the past to be able to turn off the internet, there are reports of foreign penetrations into government systems, “proof” of foreign interest in attacking U.S. critical infrastructure based on studies, and concerns about adversary capabilities based on allegations of successful critical infrastructure attacks. Which begs the question: If it’s so easy to turn off the lights using your laptop, how come it doesn’t happen more often?

The fact of the matter is that it isn’t easy to do any of these things. Your average power grid or drinking-water system isn’t analogous to a PC or even to a corporate network. The complexity of such systems, and the use of proprietary operating systems and applications that are not readily available for study by your average hacker, make the development of exploits for any uncovered vulnerabilities much more difficult than using Metasploit.

To start, these systems are rarely connected directly to the public internet. And that makes gaining access to grid-controlling networks a challenge for all but the most dedicated, motivated and skilled — nation-states, in other words.

Let’s pretend for a moment that hackers were planning to attack the United States. What would they need to do to gather enough information necessary to take out the electrical power in key parts of the country? They don’t want to fiddle at the edges, mind you. They want to have enough data to build the technical capability necessary to shut out the lights in Washington or New York or California at precisely the time and for exactly the duration they want.

For starters, they would need to know things like: Where are the power plants? What kind of plants are they? What sort of fuel do they use? Who built them and when? What sort of materials and technology were used when they were built? Who manufactured the generators, turbines and other key equipment? Whose SCADA software are they running? Who runs the plants? How does fuel, people, supplies get into or out of the plant? What sort of security do they have? And perhaps most importantly: Which plants supply power to which parts of the country?

Where to begin? Even in places like the United States, where there isn’t much you cannot find online, you’re not going to be able to get the depth and detail you need to turn off the lights with a simple network connection. You’re going to have to deploy national-level resources...

The New York Times has an article on a Chinese student who has written a paper on US power grid vulnerabilities - Academic Paper in China Sets Off Alarms in U.S..

It came as a surprise this month to Wang Jianwei, a graduate engineering student in Liaoning, China, that he had been described as a potential cyberwarrior before the United States Congress.

Larry M. Wortzel, a military strategist and China specialist, told the House Foreign Affairs Committee on March 10 that it should be concerned because “Chinese researchers at the Institute of Systems Engineering of Dalian University of Technology published a paper on how to attack a small U.S. power grid sub-network in a way that would cause a cascading failure of the entire U.S.”

When reached by telephone, Mr. Wang said he and his professor had indeed published “Cascade-Based Attack Vulnerability on the U.S. Power Grid” in an international journal called Safety Science last spring. But Mr. Wang said he had simply been trying to find ways to enhance the stability of power grids by exploring potential vulnerabilities.

“We usually say ‘attack’ so you can see what would happen,” he said. “My emphasis is on how you can protect this. My goal is to find a solution to make the network safer and better protected.” And independent American scientists who read his paper said it was true: Mr. Wang’s work was a conventional technical exercise that in no way could be used to take down a power grid.

The difference between Mr. Wang’s explanation and Mr. Wortzel’s conclusion is of more than academic interest. It shows that in an atmosphere already charged with hostility between the United States and China over cybersecurity issues, including large-scale attacks on computer networks, even a misunderstanding has the potential to escalate tension and set off an overreaction.

“Already people are interpreting this as demonstrating some kind of interest that China would have in disrupting the U.S. power grid,” said Nart Villeneuve, a researcher with the SecDev Group, an Ottawa-based cybersecurity research and consulting group. “Once you start interpreting every move that a country makes as hostile, it builds paranoia into the system.”

This is old hat in the computer security community, but I thought many of the readers of this blog might appreciate it. The really cool part starts at about 1:20 where they show video of an official government experiment in which they physically destroyed a 27 ton diesel generator just by hacking the network control interface.

Hacking and physically damaging a material fraction of the power grid would, I think, be pretty much the end of civilized life in the target country for a long time. It's not easy to do - it requires a lot of specialized knowledge and skills - but it almost certainly is possible and there are specialized offensive cyber-attack units in various countries that are tasked with knowing how to do this kind of stuff (there have been persistent rumors that the Chinese were involved in the North East power grid outage of 2003, but it's never been confirmed and might well be speculation).
