Certified Avionics Hardware Security Specialist (CAHSS)

Certified Avionics Hardware Security Specialist (CAHSS) Certification Program by Tonex

The Certified Avionics Hardware Security Specialist program by Tonex focuses on protecting safety critical electronic systems embedded in modern aircraft. Participants explore how hardware architectures, components, interfaces, and supply chains can introduce vulnerabilities that threaten flight safety and operational reliability. The program connects avionics engineering practices with robust security engineering so that hardware designs can withstand malicious tampering and unintended faults.

Strong emphasis is placed on cybersecurity for avionics hardware, including secure boot, trusted components, and protection of data paths on boards and backplanes. Learners gain practical methods to harden line replaceable units and embedded controllers used in flight control, navigation, and communication systems. By the end of the course, participants are prepared to collaborate across engineering and cybersecurity teams to ensure that avionics hardware platforms meet safety, regulatory, and cybersecurity expectations throughout their lifecycle.
