entry on the OPNAV Form 5520/20). Figure 9-1 shows a sample OPNAV Form 5520/20. Other- wise, the investigative and clearance requirements depend  on  the  level  of  access  to  classified information  needed. Security clerks may be assigned without regard to rate or grade as long as they have the clearance needed for the access they will have. Top Secret control assistants (TSCA) maybe assigned as needed and are designated in writing. The TSCA is a U.S. citizen, E-5 or above, or a civilian employee, GS-5 or above who has a final Top Secret clearance. TSCAs maybe authorized to take the following actions: Sign courier receipts and transfer of custody receipts for Top Secret materials Certify  materials  being  transferred  into Defense Courier Service and sign on behalf of the Top Secret control officer Transmit Top Secret materials Conduct required page checks of Top Secret documents Top Secret couriers, or others who handle Top Secret materials, are not considered to be TSCAs. They must have a Top Secret clearance, an understanding of the importance of the materials, and familiarity with the procedures for handling Top Secret materials. No grade or rate restrictions apply to Top Secret couriers. AUTOMATED DATA PROCESSING (ADP) SECURITY OFFICER. —Each command involved in processing data in an automated system designates an ADP security officer. The ADP security officer is responsible to the security manager for the protection of classified information being processed in the automated system. The ADP security officer is responsible to the physical security officer for the protection of personnel, equipment, and related resources. SPECIAL SECURITY OFFICER. —Certain commands in the Department of the Navy are accredited for and authorized to receive, process, and store sensitive compartmented information (SCI). These commands have a designated sensitive compartmented information facility (SCIF). A special security officer (SSO) is responsible for the operation of that SCIF and the security, control, and use of SCI. The SS0 is an officer or a civilian employee, GS-9 or above. All matters relating to SCI or SSO requirements are referred to SSO. For additional information on commands authorized to receive, process, and store SCI materials,  consult  OPNAVINST  5510.lH. Security Education Each command that handles classified infor- mation establishes and maintains an active security education program to instruct all personnel in security policies and procedures. Commands need a security education program to teach the proper way to protect classified information from hostile threats. The purpose of this program is to ensure we understand the need to protect classified information and know how to safeguard it. The goal is to develop fundamental habits of security to the point that we automatically exercise proper discretion. Once we develop the proper habits, the security of classified information becomes a natural element of every task. COMNAVSECINVCOM (OP-09N) is respon- sible for policy guidance, education requirements, and source support for the security education program. The development of security education materials for use in the Navy or Marine Corps should be coordinated with OP-09N. You do not have to coordinate development with OP-09N if  you  are  preparing  the  materials  for  use in your command program. OP-09N reviews any curriculum material being prepared for a formal training environment to make sure current policies and procedures are being taught. Training  commands  indoctrinate  personnel entering the Navy and Marine Corps about classified  information.  They  indoctrinate  new members to ensure they have a basic under- standing of what is meant by classified informa- tion and why and how it is protected. Civilians being employed by the Department of Defense for the first time also receive this basic indoctrination. The security manager is responsible to the commanding officer for security education. As a supervisor you must identify the security requirements  for  your  work  center  functions. Once you do that, ensure your personnel are familiar with those requirements. Make on-the- job training an essential part of command security education. Provide security education to all personnel, whether they have access to classified information or  not.  Provide  more  extensive  education  for 9-7
