War would be a lot safer, the Army says, if only more of it were fought by robots.

And while smart machines are already very much a part of modern warfare, the Army and its contractors are eager to add more. New robots — none of them particularly human-looking — are being designed to handle a broader range of tasks, from picking off snipers to serving as indefatigable night sentries.

In a mock city here used by Army Rangers for urban combat training, a 15-inch robot with a video camera scuttles around a bomb factory on a spying mission. Overhead an almost silent drone aircraft with a four-foot wingspan transmits images of the buildings below. Onto the scene rolls a sinister-looking vehicle on tank treads, about the size of a riding lawn mower, equipped with a machine gun and a grenade launcher.

Three backpack-clad technicians, standing out of the line of fire, operate the three robots with wireless video-game-style controllers. One swivels the video camera on the armed robot until it spots a sniper on a rooftop. The machine gun pirouettes, points and fires in two rapid bursts. Had the bullets been real, the target would have been destroyed.

The machines, viewed at a “Robotics Rodeo” last month at the Army’s training school here, not only protect soldiers, but also are never distracted, using an unblinking digital eye, or “persistent stare,” that automatically detects even the smallest motion. Nor do they ever panic under fire.

“One of the great arguments for armed robots is they can fire second,” said Joseph W. Dyer, a former vice admiral and the chief operating officer of iRobot, which makes robots that clear explosives as well as the Roomba robot vacuum cleaner. When a robot looks around a battlefield, he said, the remote technician who is seeing through its eyes can take time to assess a scene without firing in haste at an innocent person.

Yet the idea that robots on wheels or legs, with sensors and guns, might someday replace or supplement human soldiers is still a source of extreme controversy. Because robots can stage attacks with little immediate risk to the people who operate them, opponents say that robot warriors lower the barriers to warfare, potentially making nations more trigger-happy and leading to a new technological arms race.

“Wars will be started very easily and with minimal costs” as automation increases, predicted Wendell Wallach, a scholar at the Yale Interdisciplinary Center for Bioethics and chairman of its technology and ethics study group.

Civilians will be at greater risk, people in Mr. Wallach’s camp argue, because of the challenges in distinguishing between fighters and innocent bystanders. That job is maddeningly difficult for human beings on the ground. It only becomes more difficult when a device is remotely operated.

This problem has already arisen with Predator aircraft, which find their targets with the aid of soldiers on the ground but are operated from the United States. Because civilians in Iraq and Afghanistan have died as a result of collateral damage or mistaken identities, Predators have generated international opposition and prompted accusations of war crimes.

But robot combatants are supported by a range of military strategists, officers and weapons designers — and even some human rights advocates.

“A lot of people fear artificial intelligence,” said John Arquilla, executive director of the Information Operations Center at the Naval Postgraduate School. “I will stand my artificial intelligence against your human any day of the week and tell you that my A.I. will pay more attention to the rules of engagement and create fewer ethical lapses than a human force.”

Dr. Arquilla argues that weapons systems controlled by software will not act out of anger and malice and, in certain cases, can already make better decisions on the battlefield than humans.

His faith in machines is already being tested.

“Some of us think that the right organizational structure for the future is one that skillfully blends humans and intelligent machines,” Dr. Arquilla said. “We think that that’s the key to the mastery of 21st-century military affairs.”

Automation has proved vital in the wars America is fighting. In the air in Iraq and Afghanistan, unmanned aircraft with names like Predator, Reaper, Raven and Global Hawk have kept countless soldiers from flying sorties. Moreover, the military now routinely uses more than 6,000 tele-operated robots to search vehicles at checkpoints as well as to disarm one of the enemies’ most effective weapons: the I.E.D., or improvised explosive device.

Yet the shift to automated warfare may offer only a fleeting strategic advantage to the United States. Fifty-six nations are now developing robotic weapons, said Ron Arkin, a Georgia Institute of Technology roboticist and a government-financed researcher who has argued that it is possible to design “ethical” robots that conform to the laws of war and the military rules of escalation.

But the ethical issues are far from simple. Last month in Germany, an international group including artificial intelligence researchers, arms control specialists, human rights advocates and government officials called for agreements to limit the development and use of tele-operated and autonomous weapons.

The group, known as the International Committee for Robot Arms Control, said warfare was accelerated by automated systems, undermining the capacity of human beings to make responsible decisions. For example, a gun that was designed to function without humans could shoot an attacker more quickly and without a soldier’s consideration of subtle factors on the battlefield.

“The short-term benefits being derived from roboticizing aspects of warfare are likely to be far outweighed by the long-term consequences,” said Mr. Wallach, the Yale scholar, suggesting that wars would occur more readily and that a technological arms race would develop.

As the debate continues, so do the Army’s automation efforts. In 2001 Congress gave the Pentagon the goal of making one-third of the ground combat vehicles remotely operated by 2015. That seems unlikely, but there have been significant steps in that direction.

For example, a wagonlike Lockheed Martin device that can carry more than 1,000 pounds of gear and automatically follow a platoon at up to 17 miles per hour is scheduled to be tested in Afghanistan early next year.

For rougher terrain away from roads, engineers at Boston Dynamics are designing a walking robot to carry gear. Scheduled to be completed in 2012, it will carry 400 pounds as far as 20 miles, automatically following a soldier.

The four-legged modules have an extraordinary sense of balance, can climb steep grades and even move on icy surfaces. The robot’s “head” has an array of sensors that give it the odd appearance of a cross between a bug and a dog. Indeed, an earlier experimental version of the robot was known as Big Dog.

This month the Army and the Australian military held a contest for teams designing mobile micro-robots — some no larger than model cars — that, operating in swarms, can map a potentially hostile area, accurately detecting a variety of threats.

Separately, a computer scientist at the Naval Postgraduate School has proposed that the Defense Advanced Research Projects Agency finance a robotic submarine system that would intelligently control teams of dolphins to detect underwater mines and protect ships in harbors.

“If we run into a conflict with Iran, the likelihood of them trying to do something in the Strait of Hormuz is quite high,” said Raymond Buettner, deputy director of the Information Operations Center at the Naval Postgraduate School. “One land mine blowing up one ship and choking the world’s oil supply pays for the entire Navy marine mammal program and its robotics program for a long time.”

Such programs represent a resurgence in the development of autonomous systems in the wake of costly failures and the cancellation of the Army’s most ambitious such program in 2009. That program was once estimated to cost more than $300 billion and expected to provide the Army with an array of manned and unmanned vehicles linked by a futuristic information network.

Now, the shift toward developing smaller, lighter and less expensive systems is unmistakable. Supporters say it is a consequence of the effort to cause fewer civilian casualties. The Predator aircraft, for example, is being equipped with smaller, lighter weapons than the traditional 100-pound Hellfire missile, with a smaller killing radius.

At the same time, military technologists assert that tele-operated, semi-autonomous and autonomous robots are the best way to protect the lives of American troops.

Army Special Forces units have bought six lawn-mower-size robots — the type showcased in the Robotics Rodeo — for classified missions, and the National Guard has asked for dozens more to serve as sentries on bases in Iraq and Afghanistan. These units are known as the Modular Advanced Armed Robotic System, or Maars, and they are made by a company called QinetiQ North America.

The Maars robots first attracted the military’s interest as a defensive system during an Army Ranger exercise here in 2008. Used as a nighttime sentry against infiltrators equipped with thermal imaging vision systems, the battery-powered Maars unit remained invisible — it did not have the heat signature of a human being — and could “shoot” intruders with a laser tag gun without being detected itself, said Bob Quinn, a vice president at QinetiQ.

Maars is the descendant of an earlier experimental system built by QinetiQ. Three armed prototypes were sent to Iraq and created a brief controversy after they pointed a weapon inappropriately because of a software bug.

However, QinetiQ executives said the real shortcoming of the system was that it was rejected by Army legal officers because it did not follow military rules of engagement — for example, using voice warnings and then tear gas before firing guns. As a consequence, Maars has been equipped with a loudspeaker as well as a launcher so it can issue warnings and fire tear gas grenades before firing its machine gun.

Remotely controlled systems like the Predator aircraft and Maars move a step closer to concerns about the automation of warfare. What happens, ask skeptics, when humans are taken out of decision making on firing weapons? Despite the insistence of military officers that a human’s finger will always remain on the trigger, the speed of combat is quickly becoming too fast for human decision makers.

“If the decisions are being made by a human being who has eyes on the target, whether he is sitting in a tank or miles away, the main safeguard is still there,” said Tom Malinowski, Washington director for Human Rights Watch, which tracks war crimes. “What happens when you automate the decision? Proponents are saying that their systems are win-win, but that doesn’t reassure me.”

The Pentagon would consider a military response in the case of a cyber attack against the United States, a US defense official said on Wednesday.

Asked about the possibility of using military force after a cyber assault, James Miller, undersecretary of defense for policy, said: “Yes, we need to think about the potential for responses that are not limited to the cyber domain.”

But he said it remained unclear what constituted an act of war in cyberspace.

“Those are legal questions that we are attempting to address,” Miller said at a conference in Washington, adding that “there are certainly a lot of grey areas in this field.”

He said hostile acts in cyberspace covered a wide range, from digital espionage to introducing false data into a network, that did not necessarily represent full-blown war.

But he said the threat to US networks from terrorists, criminals and others was real and growing.

“Over the past decade, we’ve seen the frequency and the sophistication of intrusions into our networks increase,” he said. “Our systems are probed thousands of times a day.”

The Defense Department has about 90,000 employees and troops using computer networks, with about seven million computer devices, he said.

The US military recently created a new cyber command that will be led by Lieutenant General Keith Alexander, head of the secretive National Security Agency. Alexander was confirmed in his post by the US Senate last week.

In his written testimony to Congress, Alexander said that the new cyber command would be prepared to wage offensive operations as well, despite the risk of sustaining damage to US networks.

He told lawmakers that he expected digital operations to take place as part of a wider military campaign, but that special legal authority would be required to respond to a cyber attack staged from a neutral country.

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.”

Mr. Wortzel’s presentation at the House hearing got a particularly strong reaction from Representative Ed Royce, Republican of California, who called the flagging of the Wang paper “one thing I think jumps out to all of these Californians here today, or should.”

He was alluding to concerns that arose in 2001 when The Los Angeles Times reported that intrusions into the network that controlled the electrical grid were traced to someone in Guangdong Province, China. Later reports of other attacks often included allegations that the break-ins were orchestrated by the Chinese, although no proof has been produced.

In an interview last week about the Wang paper and his testimony, Mr. Wortzel said that the intention of these particular researchers almost did not matter.

“My point is that now that vulnerability is out there all over China for anybody to take advantage of,” he said.

But specialists in the field of network science, which explores the stability of networks like power grids and the Internet, said that was not the case.

“Neither the authors of this article, nor any other prior article, has had information on the identity of the power grid components represented as nodes of the network,” Reka Albert, a University of Pennsylvania physicist who has conducted similar studies, said in an e-mail interview. “Thus no practical scenarios of an attack on the real power grid can be derived from such work.”

The United States would lose a cyberwar if it fought one today, a former US intelligence chief has warned.

Michael McConnell, a retired US Navy vice admiral who served as ex-president George W. Bush’s director of national intelligence, also compared the danger of cyberwar to the nuclear threat posed by the Soviet Union during the Cold War.

“If we went to war today in a cyberwar, we would lose,” McConnell told a hearing Tuesday on cybersecurity held by the Senate Committee on Commerce, Science and Transportation.

“We’re the most vulnerable, we’re the most connected, we have the most to lose.

“We will not mitigate this risk,” added McConnell, now an executive vice president for consulting firm Booz Allen Hamilton’s national security business. “And as a consequence of not mitigating this risk, we are going to have a catastrophic event.”

Tuesday’s hearing came a little over a month after Internet giant Google revealed that it and other US companies had been the target of a series of sophisticated cyberattacks originating in China.

“National security and our economic security are at stake,” said Democratic Senator Jay Rockefeller, the panel’s chairman and a co-sponsor of a bill seeking to bolster public and private sector cybersecurity cooperation.

“A major cyberattack could shut down our nation’s most critical infrastructure — our power grid, telecommunications, financial services.”

James Lewis, a cybersecurity expert at the Center for Strategic and International Studies, said that government intervention would probably be needed to crack down on the “Wild West” the Internet has become.

Cyber attacks against power plants and other vital infrastructure may be higher than previously believed

A new study that interviewed power plant operators and other “critical infrastructure” indicates more than 50 percent of all U.S. power plants have had to deal with an increase in cyber attacks.

Security company McAfee funded the research, speaking with 600 IT managers and executives from 14 different nations.

Around 54 percent of those interviewed said some type of network “stealthy infiltration” took place, with the same number of executives noting they faced massive denial-of-service attacks on their networks at one point in time.

The threat of cyber attacks scare most computer users to be worried about potential data and bank theft — but security experts and government analysts note cyber attacks could be a national security issue as well.

Brazil had several high-profile blackouts in late 2009, which allegedly are tied to cyber attacks against the country’s IT infrastructure.  Brazilian officials denied cyber terrorism caused the outages, but it’s a major issue now that the 2016 Summer Olympic Games will  be held in Rio de Janeiro.

The threat of cyber attacks are even more serious now with China, North Korea, and Russia either hiring hackers directly to launch attacks, or are funneling money to hacker groups.

Power Plants Report Increase of Foreign-Based Attacks (DailyTech.com)

On a Monday morning earlier this month, top Pentagon leaders gathered to simulate how they would respond to a sophisticated cyberattack aimed at paralyzing the nation’s power grids, its communications systems or its financial networks.

The results were dispiriting. The enemy had all the advantages: stealth, anonymity and unpredictability. No one could pinpoint the country from which the attack came, so there was no effective way to deter further damage by threatening retaliation. What’s more, the military commanders noted that they even lacked the legal authority to respond — especially because it was never clear if the attack was an act of vandalism, an attempt at commercial theft or a state-sponsored effort to cripple the United States, perhaps as a prelude to a conventional war.

What some participants in the simulation knew — and others did not — was that a version of their nightmare had just played out in real life, not at the Pentagon where they were meeting, but in the far less formal war rooms at Google Inc. Computers at Google and more than 30 other companies had been penetrated, and Google’s software engineers quickly tracked the source of the attack to seven servers in Taiwan, with footprints back to the Chinese mainland.
