Excellent serie. Thank you.

Author

Thank you Brian and Alex

Author

No work with smart grid

Author

is it a successful design?

Author

present a case study

Author

thank u brian. when will be the next session on embedded systems?

Author

Thanks,Brian.  Very informative and good food for thought.  Looking forward to a 102 version.

 

Author

Hi all

 

Paul O'Brien, ABB, Australia developing a smart grid solution

 

Author

Thanks Brian and Alex; Great week session

Author

Well, time for me to go. Thanks for your questions Jeffrey.

Author

Question is if you want something that cannot be read from outside the processor.

Author

Many systems contain one of these already in their Ethernet ID.

 

Author

It would be wrong for them to dictate how something is implemented. Not all vendors may have the necessary hardware capabilities built in and this would be the standards group doing the limitation. They cannot that, they have to allow the industry to do the elimination if necessary.

Author

OK, is see that. I'm thinking of hardware more like a fusable register to hold a value as the basis for a root-of-trust.

As an exmaple - maybe you want to measure the power draw of the system before you actually load anything. That way you can detect a HW configuration change.

Author

But conceptually you just need to implement the TPM spec. I'm not sure if the Trusted Computing Group spec for TPM mandates the TPM be implement in hardware or have hardware support. But I may be wrong. 

OK - yes, there is very low level SW but also a lot of HW support for monitoring the system characteristics. You dont want to leave this to SW I suspect.

Author

For trusted program it is sort of BIOS level software, so not sure if you would develop it in the same way. It has to run directly on the HW without OS or virtualization support.

 

Author

Trusted Platform Module (Slide 9)

Do you mean trusted program?

 

Author

Is it possible to implement the TPM in software?

In that case, I have not heard of such a usage of AMT with SCADA. But it may exist.

Intels's link - http://www.intel.com/content/www/us/en/architecture-and-technology/intel-active-management-technology.html

Author

So AMT is the seperate power domain and KVM access.

Author

Gotta jump off early today folks.  Its been great - you all have my contact info.  Let's stay in touch.

Author

Right I'm just not sure what AMT is reffering to. It can't be Alternative Minimum Tax.

@Juan - it was in the reference implementation but not sure if deployed.

Author

AMT - Active Management Technology

Author

I meant whether AMT has been used in actual SCADA applications.

 

Author

MMM. Not sure what is goingon. texts stopped getting through

 

Author

And when we react we tend to fix the symptom not the cause.

As a society we tend to be reactionary. After we have been hit, we react and put better systems in place. Does anyone do backups before they have lost data? Does anyone install security software before they have been infected?

Author

Juan, what did you mean by AMT?

Thank you Brian and Alex! The sessions were very informative.

Author

@Juan - I think the biggest problem today is complacency in all industries that are not subjected to regulations. It is a cost that people do not want to eat.

Author

@Juan - that was in response to your earlier question .

Author

Thanks Brian and Alex, and EETimes, excellent presentation

Author

@Juan - I believe so, but not 100% certain on that.

 

Author

Brian, in your opinion, are the main security issues in industrial systems today, the management of a wide range of keys, or are there other infrastructure (perhaps) architectural issues as well?

 

Author

would like to see into to embedded linux system webinar like these in future and we can do simulatiion with virtual lab hardware/software

Author

@Embedded Guy - Thanks for the comment and yes it was high level, but many of the topics we talked about could be a whole course on their own. I hope it sends people in the right direction to get more relevant information.

Author

Good point - thanks

Author

@mclaus - I woyulkd suggest, just as we do with credit cards, that an order and the card information are sent separately. That way at least two parts of the system have to be comproimised before damage can be done.

Author

Thank you Alex and EEtimes team

 

Author

Thank you Brian and Alex for this great five day session.

Author

I appreciate the heads up on this Internet of Things concept.  I realize it was a high level discussion, but it is nice to know that it is going on before it all hits the market (surprise!).  Thanks Brian and Alex for great information!

Author

Thanks for a good set of lectures.

Author

thank you Alex nd Brian

Author

thanks to eetimes team also

 

@Jeff - many people think it was a large country that was to blame.

 

Author

Brian / Alex - thanks for putting this together.  Very interesting.  Hope we do more of these.

Author

I have learned a lot on this Class.

Thank you Brian and Alex.

Author

thank you brain & alex 

 

Thanks Brian and Alex. It's been a great week. See all next time.

Author

Thank you for the lectures Brian, very informative!

Author

Thank you Brian and Alex.

Author

There is - but since update in basically an automated process, we have essentially embedded a password into the code - a very bad practice.  It is encrypted and known to only a few in our organization, but still it is probably vulnerable to being hacked if somebody were to work at it hard enough.  We are planning to change to a dynamically generated key that will be provided via a newwork connection back to our central service organization - but we don't have that infrastructure quote ready yet. 

Author

Thank you Brain and Alex for the presentaion.

Is there an authentication protocol in the update API?

Stuxnet is very complex and bears the marks of being done by a larger group that had motives beyond simple credit card theft etc. Do we have any idea who they were?

Author

There are ways to re-register the process code with the boot process.  During updates, there is an API that get exercises to re-register the new process code.  Updates to the boot image contain process registrations already. 

Author

Oops, I meant AMT

 

Author

Has IMT been used with SCADA?

 

Author

@mclaus, how do you deal with updates? Update both the bootcode and process code?

We ensure that any code that runs on our system is known.  The boot process gets the boot image from a known, encrypted, secure source.  Any process code that is run after boot must be registered with the boot image and it;'s image much match the one that was registered.

Author

Is it possible to implement the TPM in software?

In my world "CIP" is the Common Industrial Protocol.

Author

Thank you Brian and Alex.

Author

Right now, its usually a propriety standard in a license frequency. Very small amounts of data.

@mclaus - Thanks for the security example!

Author

How does the Smart Meter work?

How does it  trasmit it's DATA?

Author

Yes - we sell the 'the ability to treat patients' with our products to our customers over the web.  They pay, we download a certain number of treatments into the system to allow them to deliver the treatments.  Often we place the equipment of free, but make money by selling the tretments.

A group in China learned to hack the code that allowed download of treatment, as was selling that hack to our customers.  Big problem, but we did finally get it resolved.

Most companies do not brag about their security vulnerabilities.

Rockwell is also working on the SmartGrid, in standards and in project space.

NEXT UPCOMING BROADCAST
Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses? Panelists: Chad Sweet, Director of Engineering, Qualcomm; Yannick Levy, VP Corporate Business Development, Parrot; Jim Williams, ex-FAA drone chief; Michael Drobac, Exec. Director, Small UAV Coalition; Moderator: Junko Yoshida, Chief Int'l Correspondent, EE Times
