Navigating DO-326A and ED-202A Airworthiness Cyber Security Certification

Security risk assessment, threat modeling, and security verification for type certification of modern aircraft.

Airworthiness Security Risk Assessment (ASRA)

Unlike IT security, DO-326A focuses strictly on the airworthiness consequences of cyber events—preventing cyber incidents from compromising the safety of flight, structural integrity, or crew situational awareness.

Security Effectiveness Verification (DO-356A)

RTCA DO-356A specifies mandatory penetration testing, vulnerability scanning, and fault injection on aircraft iron bird testbeds before commercial passenger certification can be granted.

End-to-end alignment with FAA AC 119-1 and EASA Part-IS regulations
Systematic Threat Environment Description (TED) documentation
