Certified Avionics System Security Architect (CASAS) Certification Program by Tonex
The Certified Avionics System Security Architect CASAS Certification Program by Tonex prepares senior engineers and architects to design secure avionics systems that withstand modern threat environments while still meeting rigorous safety and performance constraints. The program focuses on secure by design thinking for integrated modular avionics, open architectures, and complex system of systems platforms.
Participants learn how to map mission requirements, safety assumptions, and regulatory expectations into concrete architecture decisions and verifiable security controls. A strong emphasis is placed on cybersecurity impact across the entire aircraft lifecycle, from concept and early trade studies through integration and sustainment. By the end of the program, participants are able to build defensible architectures, articulate clear trust boundaries, and justify their design choices to certification authorities, program leadership, and cybersecurity stakeholders.
