This thesis investigates the possibility of implementing a multilevel secure local area network on
a medium-sized ship. In particular it focuses on medium-sized ship communications suite connectivity
to a GateGuard computer system, and then on incorporating systems that have been developed under
the Navy's transition plan for the Defense Message System; specifically the Multilevel Mail Server being
installed at Navy Telecommunications Centers. A review of data communications security considerations
as well as DoD and Navy directives is provided for background on the accreditation requirements of
multilevel secure systems. Additionally two commercially available products, the VERDIX Secure Local
Area Network and Trusted Information Systems' XENIX trusted operating system arc reviewed and
then shown how they could potentially be integrated into a shipboard local area network. A potential
configuration is provided with recommendation for further studs of system application compatibility.
