NSA Patents a Way To Spot Network Snoops

narramissic writes "The National Security Agency has patented a technique for figuring out whether someone is messing with your network by measuring the amount of time it takes to send different types of data and sounding an alert if something takes too long. 'The neat thing about this particular patent is that they look at the differences between the network layers,' said Tadayoshi Kohno, an assistant professor of computer science at the University of Washington. But IOActive security researcher Dan Kaminsky wasn't so impressed: 'Think of it as — if your network gets a little slower, maybe a bad guy has physically inserted a device that is intercepting and retransmitting packets. Sure, that's possible. Or perhaps you're routing through a slower path for one of a billion reasons.'"

    these false positives really begin to add up. Couple this will all the lame-brained terrorist detection schemes that create millions of false positives and we can see the plan to get America out of recession is to have every single citizen working for the government hunting snipe.

    Nah. What makes it newsworthy is that the snoops are patenting tools which can detect their own snoopage.

    Counter-snooping this way is now a patent infringement as well as anything else, and the laws seem much tougher for that crime. Pursue 'em for one thing, nail 'em to the wall with another.

    The best this will be able to do is detect changes in latency patterns, possibly being able to narrow it down to certain network segments depending on how many devices are having their details analysed in real time.

    "NSAapp: Latency change detected in segment AA23. No idea what it might mean. Send the intern."

    Try a more recent tax form - proving you paid taxes more recently than 909 years ago is unlikely to impress them.

    From what I understand, they have a couple of honest people working at both places.
