Certified Aircraft Software Security Specialist (CASSS) Certification Program by Tonex
The Certified Aircraft Software Security Specialist CASSS Certification Program by Tonex prepares engineers and security professionals to protect safety critical avionics software from evolving digital threats. The program connects aircraft certification requirements with secure software engineering so participants understand how design choices influence both safety and protection. Learners explore threat modeling, secure coding practices, and vulnerability assessment tailored to airborne systems and ground support environments.
The course highlights how cybersecurity weaknesses can cascade into operational disruption, safety incidents, and regulatory exposure across the aircraft lifecycle. Participants practice thinking like both attackers and defenders while still meeting stringent aviation assurance objectives. Dedicated attention is given to secure integration with aircraft networks, maintenance systems, and supply chain partners so that cybersecurity is treated as an continuous discipline rather than a one time checklist. By the end of the program, attendees gain a practical roadmap for integrating cybersecurity into requirements, architecture, verification, and maintenance activities for modern aircraft software.

Course Delivery
The course is delivered through a combination of expert led lectures, interactive discussions, structured case studies, and guided workshops focused on aircraft software scenarios. Participants engage with practical examples drawn from commercial and defense aviation programs to connect theory with real world practice. Carefully designed exercises reinforce threat modeling, secure design decisions, and risk analysis for avionics and support systems. Throughout the program, cybersecurity considerations are woven into every activity so that learners experience security as an integral part of aircraft software engineering and certification work rather than an afterthought.
Assessment and Certification
Participants are assessed through periodic quizzes, short written assignments, and a final integrative assessment that applies concepts to a realistic aircraft software security scenario. Performance across security design, risk analysis, and assurance thinking is emphasized to reflect the multidisciplinary nature of modern aircraft programs. Upon successful completion of the assessments, participants receive the Certified Aircraft Software Security Specialist CASSS Certification from Tonex, demonstrating their capability to embed cybersecurity into aircraft software development and certification efforts.
