Aviation standards divide aircraft into four strictly isolated domains: Aircraft Control Domain (ACD), Airline Information Services Domain (AISD), Passenger Information and Entertainment Services Domain (PIESD), and Passenger Owner Devices (POD).
AvionicsOperations implements certified multi-layer firewalls and optical isolators, ensuring that no hacker on the passenger Wi-Fi network can ever inject packets into flight control or cockpit navigation systems.
