Protecting factory networks
William K.   10/9/2011 10:57:44 PM

The fact is that my assertion was that a primary way to be secure was to not have the capability present, not wired of fiber or wireless. Tha capability of remotely changing the program would not be present in the system. No, there is no question about it being less convenient, but a disaster is more inconvenient. But if the way to change a calibration or a program requires physicaly operating a switch at the machine, then all remote hackers are kept out.

Thanks Ivan, Chuck, William for great points.  William, the ideal case you raised of a physical control over the hardware network might be re-interpreted by others to say a hard-wired physical-layer network, preferably fiber, should be used for changes in configuration.  Yet someone will always come in and demand wireless updates for reasons of cost, and all the best ideas for trusted systems fly out the window.  This TCG work will be interesting to watch.

Trusted security effort might possibly protect factory networks.

The way to protect factory and any other important machine control networks is to not allow the capability of external modification to exist at all. Of course it is more convenient and cheaper to change the program and the parameters over the network. It is also not possible to have this ability and have it be secure, we all know that. But real security does have a real cost, which is that somebody would need to actually visit the controller and alter the program or settings. Any outside access is not completely secure, only fairly secure, and we all know that any security measures only last untill somebody cracks them. And that always happens.

So it becomes a trade-off of costs-which costs more, manual updates or hackers damage? Each can be calculated, and then a decision can be made.

I agree, Ivan. This underscores the importance of recent "safety microcontroller" rollouts by TI, Freescale, and Renesas. The Embedded Systems Working Group is one more sign that we are collectively paying attention to vulnerabilities of power plants, air traffic control systems, financial systems and, yes, train yards.

Long Overdue

This is long overdue.

The truth of the matter is that the US is extremely vulnerable on so many fronts in this cyber war.  We have so much of our infrastructure that is accessible through the various networks.  air traffic control and electrical generation and distribution systems are all vulnerable.  In fact it is a good bet they are already penetrated and sleeper code is in place to do harm when the controlling organization or country wants to initiate an attack.  I venture it is a safe bet that the US is the most vulnerable of any country.

Another long overdue consideration is that defense in cyberspace is far behind offensive capabilities.  Countries like North Korea are not as susceptible to cyber attack as we are.  They just don't have that much infrastructure to protect.

It will take a great deal of attention and money to bring this situation under control.  Embedded chips made in other countries may not be safe from malicious code being designed into the system fromt he beginning.  Detecting this and preventing it use will require additional efforts that might not be possible with the existing systems.

More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
