CASSE-A – Aviation Software Security Engineer Certification Program by Tonex
CASSE-A prepares aviation and aerospace professionals to design, develop, and protect safety critical software in increasingly connected aircraft environments. The program focuses on secure engineering practices across avionics platforms, from embedded flight control software to integrated ground support systems. Participants learn how to align safety driven standards with modern security requirements, ensuring that flight software behaves predictably even under hostile conditions.
A strong emphasis is placed on cybersecurity in avionics networks, data buses, and airborne applications so that digital threats do not undermine safety objectives. Learners explore how to integrate cybersecurity into system requirements, architecture, coding, and verification activities while maintaining compliance with aviation regulations and certification guidance. By the end of the program, participants will be able to identify and mitigate software vulnerabilities across the aircraft lifecycle and communicate security risks effectively to engineering, operations, and regulatory stakeholders.
