National Cross Domain Strategy & Management Office

Information needs to be shared with stakeholders across international, governmental, agency, and classification boundaries. Cross domain technology plays a critical role in this sharing; cross domain solutions are controlled interfaces that provide the ability to manually or automatically access or transfer information between different security domains.

NSA's National Cross Domain Strategy & Management Office (NCDSMO) is the focal point for U.S. Government cross domain capabilities and mission needs (pursuant to the authority of Executive Order 12333 and National Security Directive 42).
