Formulate  and  coordinate  the  command's security education program. Ensure  that  threats  to  security,  compromises,  and other  security  violations  are  reported,  recorded  and, when  necessary,  investigated. Administer   the   command's   program   for classification,  declassification,  and  downgrading  of classified material. Maintain  liaison  with  the  public  affairs  officer  to ensure that proposed press releases do not contain classified information. Ensure  compliance  with  accounting  and  control requirements for classified material, including receipt, distribution, inventory, reproduction, and disposition. The duties of the security manager are numerous. Refer to Department of the Navy Information and Personnel   Security   Program   Regulation, OPNAVINST   5510.1,   for   more   information concerning  his/her  duties. Top  Secret  Control  Officer Each   command   that   handles   Top   Secret information must designate, in writing, a Top Secret control officer (TSCO). The person designated must be an officer, senior non-commissioned officer, or a civilian employee GS-7 or above. The TSCO must be a U.S. citizen with a Top Secret clearance. The TSCO is responsible to the security manager for   the   receipt,   custody,   accounting   for,   and disposition of Top Secret material in the command. Procedures for the duties of the TSCO are set forth in OPNAVINST  5510.1. Security Assistant The security assistant must be a U.S. citizen and either an officer, an enlisted person E-6 or above, or a civilian employee GS-6 or above. The designation must be in writing. The assistant security manager does not require a BI unless he/she has been authorized to issue security clearances. The security assistant assists the security manager in his/her duties. ADP/Information Systems Security Officer Each command involved in processing data in an automated system must designate an ADP/IS security officer. The ADP/IS security officer is responsible to the security  manager  for  the  protection  of  classified information being processed in the automated system and is responsible to the physical security officer for the protection of the personnel, equipment, and related resources. SECURITY EDUCATION Each command in the Department of the Navy (DON)  that  handles  classified  information  will establish  and  maintain  an  active  security  education program to instruct all personnel, regardless of their position,  rank,  or  grade,  in  security  policies  and procedures.  The  overall  purpose  of  the  security education program is to make sure that all personnel understand the need to protect classified information and know how to safeguard it. Commanding  officers,  through  their  security managers,  are  responsible  for  security  education  in their commands, and for ensuring it is afforded a significant  share  of  the  time  dedicated  to  command security. 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
