I just passed the CISSP and I'm always looking for more on the topics I cover in a particular exam. i came accross this class on www.coursera.org called Information Security and Risk Management in Context. 10 week course that JUST started. If anyone is in the InfoSec field and either studying for an exam or just wants some more brain food, check it out, it looks to be good from what Ive seen so far on it. It is hosted by the University of Washington. Week 1 is basically due today but they give you a week leeway. Take a look if you are interested.
The course states it might take between 3 and 5 hours per week to complete each week. Not bad for a side class.
Additionally, the site has 198 classes on everything under the sun from Cryptography (yes there is a class on specifically Crypto, it is very advanced) to Model Thinking. This isn't just for InfoSec students.
