With the increasing adoption of more complex electronic systems, larger code bases, and network connectivity, the threat surface for Aerospace applications is growing significantly. Cybersecurity has become paramount to managing operational and safety risks of avionics systems overall and even for devices at the edge such as data acquisition and control hardware. DO-326a calls for the assessment or risk in avionics systems. When the operational and safety aspects of cyber-physical hardware at the edge are considered in a risk assessment, naturally a Zero-Trust set of controls emerge. Zero-Trust at the edge is good approach to managing cyber-risk and to help ensure the safety and efficiency of flight operations. |
