Considerations for a shipboard multilevel secure local area network

NPS Calhoun · John W. Riley III ·

Executive Summary

This thesis investigates the implementation of a multilevel secure local area network (LAN) on medium-sized ships, focusing on integrating communication suites with GateGuard and the Defense Message System's Multilevel Mail Server. It reviews data communication security, DoD/Navy directives, and explores commercial products like VERDIX Secure LAN and Trusted XENIX for potential integration. The document proposes a configuration and recommends further study on application compatibility.

Why It Matters

This document is crucial for defense analysts as it details early considerations for secure shipboard networks, a foundational element for modern naval command, control, and intelligence operations. Understanding these historical challenges and proposed solutions provides context for current naval cybersecurity and network architecture.

Key Takeaways

  • Implementing multilevel secure LANs on ships is critical for integrating diverse communication systems and enhancing combat readiness.
  • Early naval network designs aimed to reduce paper documentation and improve information flow, facing challenges with system integration and user training.
  • Commercial products like VERDIX Secure LAN and Trusted XENIX were considered for integrating secure communication capabilities into shipboard networks.
  • The Defense Message System (DMS) and Multilevel Mail Server (MMS) were key components in the Navy's strategy for secure message handling.

Strategic Relevance

The strategic relevance lies in the foundational work for secure shipboard communications, which is vital for maintaining information superiority, protecting classified data, and ensuring effective command and control in naval operations. This early exploration of MLS LANs directly impacts the resilience and security of naval platforms.
