Due to limited resources and inconsistent guidance from the U.S. Federal Government, Department of Defense, and multiple environments within the intelligence community, the defense intelligence agencies each developed their own methods to deliver security awareness information. These multiple delivery methods may be providing different levels of security awareness information that could result in staff within one agency having different levels of security awareness skills, knowledge, and abilities. This same situation exists in the commercial, private, and academic sectors that depend on the Federal Government, the National Institute of Standards and Technology (NIST), and the Department of Defense as the examples and subject matter experts for security information delivery. The study created an intensive, holistic description of current methods of delivering security information using Gilbert's Behavior Engineering (BEM) as the framework. The study questions provided an initial guide for discussion with the study participants addressing BEM factors including environmental and the repertory of behavior support factors of motivation, instrumentation, and information. The study indicated that defense intelligence agencies were consistent in their definition and belief that security directly supported their agency's mission, vision, and values. Each of the agencies used some form of development methodology, and the agencies assumed the programs they delivered were compliant with requirements and were a benefit to their staff. The study suggested that the agencies did not have a documented or metric driven method that supported their assumptions about the success and benefit of their deliveries. The study suggested that very few agencies considered many of the BEM factors in their delivery methods and that there was very little feedback or validation that their security awareness deliveries were providing the required security information.
