The security field is an excellent illustration of the maxim that ``the more things change, the more they stay the same.'' Thus while technical details change, underlying security principles remain remarkably constant. Dr. Bell's talk ``Everything I Needed to Know about Security, I Learned in 1974'' covers the lessons he learned in his early modeling work, how they have remained valid since, and how those principles inform his view of 21st-Century challenges.

About the Speaker

David Elliott Bell, Ph. D., is the co-author of the widely-known ``Bell-La Padula security model." His work in security has been varied, from the conceptual security of his modeling work to security architectures, operating system security, database management security, network security, formal verification, public-key technology, and standards and guidelines for security practice.

In addition to security, he has also contributed in systems design and implementation, acquisition, integration, and, not least, in passing his insight along through formal and informal training and education. He has been a guest lecturer at the U.S. Military Academy at West Point and the U.S. Naval Academy at Annapolis.

Major customers benefitting from his contributions include the Department of Defense, especially the U.S. Air Force, DIA, and the National Security Agency (where he was presented the NSA Meritorious Civilian Service Award); the Department of Homeland Security; and the Department of Energy.

Since retirement, he has given invited addresses at ACSAC, Mississippi State University, the University of Nebraska, Omaha, and Winston-Salem State University.

Unless otherwise noted, the security seminar is held on Wednesdays at 4:30P.M. STEW G52 (Suite 050B), West Lafayette Campus. More information...
