CAASA – Certified Aviation Avionics Security Assessor Certification Program by Tonex
CAASA prepares professionals to evaluate, validate, and assure the security posture of modern aviation avionics systems across aircraft platforms and ground support environments. The program focuses on how interconnected avionics, data links, and software defined functions introduce new attack surfaces and require rigorous, structured assessment methods. Participants learn to interpret regulatory expectations, align security assurance activities with safety critical certification flows, and communicate risks in a way that flight operations and engineering teams can act on.
The course emphasizes practical assessment techniques that fit into real engineering and maintenance workflows. Strong attention is given to how cybersecurity weaknesses in avionics can cascade into safety incidents, operational disruption, and trust issues between airlines, OEMs, and regulators. Graduates are equipped to translate cybersecurity findings into prioritized remediation paths that support continuous airworthiness and resilient, secure flight operations.
