This is a three-year old RAND study for the Air Force describing the threat picture as it was then preparatory to standing up the 8th AF (which didn't, ultimately; what we got instead was US Cyber Command and the individual service components).
There is nothing ground breaking here, and for the price vs content, I would not recommend buying it. Instead look to the RAND site for a free PDF copy of the report and spend an hour looking it over.
