Submarine Open Architecture Cybersecurity & Zero Trust Training by Tonex
Modern submarine open architectures join diverse hardware, operating environments, supplier software, and mission data services, making implicit trust between components increasingly difficult to justify. This course examines cybersecurity engineering for integrated submarine systems through zero trust principles, technical segmentation, identity-aware access, secure interfaces, and controlled lifecycle changes. Participants review how to define protected assets, map information flows, assign trust boundaries, and verify defensive controls at component and system levels. The course considers constrained onboard connectivity, restricted maintenance windows, and long hardware service lives when evaluating realistic defensive architecture options.
Cybersecurity assurance must include shared hardware controllers, privileged services, and supplier-delivered updates as well as application traffic. Clear cybersecurity requirements make trust assumptions testable and incident response responsibilities actionable.
The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in submarine integrated hardware and software engineering projects, including architecture threat models, trust boundary diagrams, secure interface specifications, and cybersecurity control verification evidence.
