NSA says Internet Needs Re-design

The U.S. Internet’s infrastructure needs to be redesigned to allow the NSA to know instantly when overseas hackers might be attacking public or private infrastructure and computer networks, the agency’s leader, General Keith Alexander, said today.

Alexander spoke at the annual Def Con computer hacking conference in Las Vegas. It was a symbolic appearance that he said was motivated by a need to interest the hacker community in helping to make the Internet more secure.

Alexander, who is also commander of the U.S. Cyber Command, described the Internet as “at great risk from exploitation, disruption, and destruction.”

In recent years, many Internet users have become familiar with the idea that websites can be knocked offline by denial of service attacks, such as those employed by online activist groups such as Anonymous. “My concern is that it’s going to flow into destructive attacks that could have consequences for our critical national infrastructure and the Internet itself,” said Alexander.

The decentralized nature of the Internet, and the fact that the global network is built from a thicket of independent public and private networks, is limiting efforts to protect against such attacks, said Alexander, because it doesn’t allow the NSA or law enforcement to easily track Internet activity. “We do not sit around our country and look in; we have no idea if Wall Street is about to be attacked,” said Alexander.

The NSA is already running a trial with 17 U.S. defense companies intended to demonstrate technology that could be deployed to change that. Under the Defense Industrial Base (DIB) Cyber Pilot, Lockheed Martin and other companies set up their computer security systems to automatically alert the agency when the alarm is tripped. They automatically pass a summary of what was detected and the IP address associated with the event to the NSA over the Internet. “All you need to pass is the fact of a signature and IP address in real time, and we can take it from there,” said Alexander.

Alexander suggested that the NSA should be given a wider checkpoint role across the Internet to protect core infrastructure and all vital systems connected to it, drawing an analogy with an automatic road toll system. “What we need for cybersecurity is something analogous to that,” he said. “Think of us as the EZ Pass on the highway.”

Alexander dismissed possible concerns about giving the NSA too much oversight into how the Internet is being used. “When you go down the highway, and you go down the EZ Pass lane, what you’re doing is sending that code. That system is not looking in your car, reading the e-mail, or intercepting anything, it’s just getting that code.”

Alexander also suggested rolling back the decentralization of computer networks by saying that “thin client” computing should be considered by large organizations. Long out of fashion, the thin client approach gives individual users relatively simple computers that access computing resources that are controlled centrally. That could help large organizations such as the U.S. Department of Defense, which currently has some 15,000 separately configured and operated sections of its network, said Alexander, offering too many potential areas of attack.

Speaking about the fact that some Def Con attendees are leery of the NSA interest in their event, a hacker known as Dead Addict, who has helped organize the Def Con event since the first conference 20 years ago, said he was pleased that Alexander wanted to engage with the hacker community. “Many of us fear their surveillance and offensive capabilities, but many of us share an interest in that [offense] as well,” he said. He pointed out that the activities of all hackers at Def Con rely on the Internet to be resilient and trustworthy. “Our interests overlap.”

Alexander claimed that taking such steps could also be lucrative for the U.S., and foster new areas of business. “This could help us with our economic growth. Look at what fuels our economy,” he said. “We’re the ones that helped develop, and helped build the Internet; we ought to be the first to secure it.”
