Apparently, TSA is going to recruit an army of computer security experts from pizza boxes and gas pumps, or maybe give them a week of on-the-job training .... The Examiner (23 Jan 2012): TSA memo reveals railway computer hacked IB TImes (24 Jan 2012): Computer Hackers Hijack US Trains - TSA Memo Wired/Thread Level (24 Jan 2012): Hackers Breached Railway Network, Disrupted Service This is not a transportation problem. This is symptomatic of a much larger issue that industry must address, e.g. Wired/Threat Level (24 Jan 2012): 10K Reasons to Worry About Critical Infrastructure Interesting that Wired/Threat Level posted the two articles about the same time. At least somebody is looking at the larger picture. If they want to solve it, keep TSA out of the way. It won't do much good if the train stays on the track while the chemical plant explodes. The 10K figure is incredible. I've worked with industrial control systems for years. A common refrain is "nobody would ever allow their control systems to be connected to the internet". Ha!
