Re: Segemented data
Thanks for your reply Theresa.  I totally agree that this could be a sensible measure for a couple of critical assets.  I could see using it for private keys or highly sensitive proprietary information.  Still can't see a practical way of making it work for something that's going to be frequently accessed by a variety of users, like a schedule.  I'm not sure if you can give any more specifics due to the nature of the job and what you were protecting, but kudos for making it work.

Thanks again for the article and taking the time to reply.

Great Post Recognizing the Human
 I really like your premise of human factor failings in this post. This harkens back the human-centric design of Alan Cooper's "The Inmates are Running the Asylum." He used the creation of "personas" to help humanize the likely users in the design of software or other products. I suspect that a similar profiling will help to develop more elegant cybersecurity policies that anticipate the most likely human failings.

Re: Segemented data
Hi Ryon, thanks for asking your question!  In my humble opinion, you would do both.  Because safety measures for data such as encryption or two factor authentication are not 100% bullet proof solutions, you want to make sure you segment your data.  When that breach happens, they can only steal one piece and you slow them down from taking more of your information.  This is hard to do which is why I only recommend this for 1-2 of your most critical information assets.  Hope this a helpful explanation.

Segemented data
I'm unclear on what you're trying to get at with segmenting data like the President's schedule.  What is the benefit of having it segmented across multiple teams or systems?  How does this work in practice?  As you note, the amount of effort and synchronisation would be high.  There are lots of easier ways to secure data and restrict access than segmenting it all over the place.  You cite this as a "similar strategy" to how banks use 2 factor authentication, but this sounds like something quite different.  Grateful if you can clarify, thanks for the article.
