Information Assurance Technical Framework Forum
"The
Information Assurance Technical Framework Forum (IATFF) is a National Security
Agency (NSA) sponsored outreach activity created to foster dialog amongst U.S.
Government agencies, U.S. Industry, and U.S. Academia seeking to provide their
customers solutions for information assurance problems."
They have quite a few documents for download - although, on first glance, not totally cutting edge. (behind what you learnt to expect and love from folks like the NIST...)
