SECURITY PRINCIPLES The Department of Defense (DOD) security formula is based on the premise of circulation control (the control of dissemination of classified information). According to this policy, knowledge or possession of classified defense information is permitted only to persons whose official duties require access to the information (“need to know”). CLASSIFICATION CATEGORIES LEARNING OBJECTIVES: Identify and define the classification designations and special markings. Official information that requires protection in the interests of national security is placed into one of three categories: Top Secret, Secret, or Confidential. Following are examples and definitions of each category. TOP SECRET Top Secret is the designation applied only to information that requires the highest degree of protection. It is of such a nature that its unauthorized disclosure could reasonably be expected to cause 11-2
