He taught at the U.S. Air Force Academy for seven years where he developed and taught two courses on Computer Security and Information Warfare. For the last two years, he has been heavily involved in developing and promoting the idea of conducting an annual collegiate cyber security competition. In 2002, Dr. White was chosen to direct the Dark Screen cyber terrorist exercise conducted in San Antonio, Texas. This exercise, the first of its kind, brought together over 225 individuals from the military, various levels of government, industry and academia to examine the ability of San Antonio, Bexar County and surrounding region to react to a cyber attack on the area's critical infrastructures. The event, which also had representatives from state and federal agencies, received national attention and expanded its scope to an even larger exercise in 2003. Since then he has been in charge of other sector-based and community exercises around the country. Dr. White has written and presented numerous articles and conference papers on security. He is also the co-author for six textbooks on computer and network security and has written chapters included in two other security books.
