Cybersecurity in the Air: Addressing Modern Threats with DO-326A

Aviation cybersecurity has become a critical issue across the globe. Not only do millions of passengers depend on airlines to get them safely from point A to point B every day, but manufacturers, shipping services, and militaries rely on aircraft systems to support supply chains and execute missions.

Known as the “Airworthiness Security Process Specification,” DO-326A (and its European counterpart, ED-202) is the aviation cybersecurity standard developed jointly by the Radio Technical Commission for Aeronautics (RTCA) and the European Organisation for Civil Aviation Equipment. The original edition, DO-326, was issued in 2010; its revised version, DO-326A, was issued in 2014.

In this whitepaper, we cover the seven steps of DO-326A compliance, and:

• How it differs from DO-178, ARP4754, and DO-254
• Who and what DO-326A applies to
