There are a plethora of new books at the RSA conference book store.
Here is my pick of the best of them, which I will be reading over the course of the next few months:
Threat Modeling: Designing for Security - Adam Shostack
Data-Driven Security: Analysis, Visualization and Dashboards - Jay Jacobs and Bob Rudis
Unmasking the Social Engineer: The Human Element of Security - Christopher Hadnagy
