This is a Department of Navy instruction document (SSPINST 5230.11B CH-1) regarding electronic transmission of controlled unclassified information (CUI) for Strategic Systems Programs (SSP). The instruction provides detailed policies and procedures for protecting and transmitting CUI via electronic means.

The document outlines specific requirements for handling CUI, including: encryption requirements for SSP e-mail containing CUI, restrictions on using personal devices, approvals needed for cloud services (must be authorized by SPCIO), and requirements for contractor networks. Key provisions include that SSP Voice-over-IP is preferred for discussing CUI during telework, unauthorized disclosures must be reported per referenced policies, and CUI must be properly marked with required labels. The instruction applies to the entire SSP enterprise including headquarters, program offices, weapons facilities, and contractors. Notably, it prohibits posting CUI on public websites and requires Public Affairs Officer review of unclassified information before public release. The document supersedes the previous version (SSPINST 5230.11A) and includes updated guidance on external system approvals and CUI markings.
