Hi Meredith, There is a lot of information in the area. In the 70's IBM did a lot of research on this (as well as others). It mostly came out of IT and human factors publications. I would imagine that in the era of homeland security this is getting some additional funding.
When I worked in this field, we used to explain that usability and security, at the extremes were two opposite ends of a continuum. Adding to one nearly always compromised the other. I know it is a bit simplistic, but it works as a quick explaination. If you can get access to Forresters, I know they have a pile of info on the topic, sorry I can't give you anything specific right now.
