NSA receives advice from the nation's experts in a variety of technical fields through their participation in the National Security Agency Advisory Board (NSAAB), which has been in existence in one form or another since 1953. When Congress passed Section 501 of the Intelligence Authorization Act for Fiscal Year 2005, the existing NSAAB was reconstituted as an advisory body not subject to the Federal Advisory Committee Act (FACA). Section 501 modified the National Security Agency Act of 1959 (50 USC 402 note) to establish what the statute calls the National Security Agency Emerging Technologies Panel to study, assess, and periodically advise, the NSA Director on the research, development, and application of existing and emerging science and technology advances, advances in encryption, and other topics. It specifically states that FACA does not apply to the panel. By internal NSA policy, and to avoid confusion among those with whom the NSAAB works, the National Security Agency Emerging Technologies Panel continues to be referred to as the National Security Agency Advisory Board (NSAAB).
