For Official Use Only (FOUO) FOUO   is   the   designation   used   on   official information not requiring a security classification but which must be withheld and protected from public release.  Unclassified  messages  containing  FOUO information must have the abbreviation “FOUO” after the designation “UNCLAS.” Encrypt for Transmission Only (EFTO) Certain categories of unclassified messages maybe identified  as  having  potential  value  if  subject  to analysis, but do not meet the criteria for security classification.  The  special  designation  “EFTO”  was established to protect these unclassified messages during electrical transmission. EFTO is not required on unclassified messages addressed  exclusively  among  Navy,  Marine  Corps,  and Coast Guard commands. EFTO is authorized for use within  the  Department  of  Defense,  including  the National Security Agency. However, EFTO is required on  FOUO  messages  addressed  to  DOD  activities outside the continental United States. Bear in mind, however, that just because information is FOUO, it is not automatically EFTO, and vice versa. As we mentioned earlier, EFTO is a transmission marking  for  unclassified  messages.  FOUO  markings, however, define a certain category of information requiring  special  handling.  Neither  FOUO  nor  EFTO markings   are   security   classifications;   both   are special-handling designations. You can find detailed information on EFTO and FOUO markings in  Basic Operational Communications Doctrine (U), NWP 4. SPECAT The  SPECAT  marking  means  special  category. SPECAT  messages  are  classified  messages  identified with a special project or subject. SPECAT messages require special-handling procedures in addition to the handling procedures for the security classification of the message. There are four SPECAT categories: SPECAT; SPECAT EXCLUSIVE FOR (SEF); SPECAT   Single   Integrated   Operational Plan-Extremely    Sensitive    Information (SIOP-ESI); and PSEUDO-SPECAT. SPECAT  and  SPECAT  EXCLUSIVE  FOR  messages must be at least Confidential. SPECAT SIOP-ESI messages  are  always  Top  Secret.  PSEUDO-SPECAT messages are normally unclassified messages that require   limited   distribution.   Examples   of PSEUDO-SPECAT messages include AMCROSS messages, urinalysis test results, and HIV test results. SPECAT messages are handled only by those personnel who are authorized by the commanding officer   in   writing   to   view   them.   The   types   of information   assigned   SPECAT   and   handling procedures can be found in NWP 4 and in  Fleet Communications (U),  NWP 4, respectively. PERSONAL FOR PERSONAL  FOR  is  the  marking  applied  when message distribution must be limited to the named recipient. Only flag officers, officers in a command status,  or  their  designated  representatives  may  originate PERSONAL FOR messages. NATO RESTRICTED The  United  States  does  not  have  a  security classification  equivalent  to  NATO  RESTRICTED. NATO  messages  classified  as  restricted  must  be safeguarded in a manner similar to that for FOUO messages. Messages originated by NATO must be handled  in  accordance  with  NATO  Security  Procedures (U), OPNAVINST C5510.101. ALLIED RESTRICTED The  United  States  does  not  have  a  security classification  equivalent  to  ALLIED  RESTRICTED. However, these messages must be handled in the same manner as Confidential messages. U.S.-originated messages   containing   ALLIED   RESTRICTED information are marked as “Confidential” immediately following the security classification. The   Security  Manual   contains   complete information  on  paragraph,  subparagraph,  and  document markings. HANDLING AND STORAGE OF CLASSIFIED MATERIAL Classified messages must be provided accounting and control procedures that correspond to their assigned classification.  Accounting  and  control  of  classified messages serve the following functions: 5-6
