The aviation industry is reviewing updated cybersecurity requirements in network segmentation, access control, threat detection, and patching. The attempt to increase industry security comes as the Biden administration aims to strengthen critical infrastructure cyber defences. The aviation sector is also facing threats from emerging digital technologies, like 5G and smart devices. Employees in critical roles, such as pilots and air traffic controllers, have limited training in managing cyber incidents, while the threat surface has increased due to the digital transformation of air traffic management systems and airport functions. While details of the new cybersecurity requirements for the aviation sector remain unclear, they will require companies to keep up with hardware and software patches, strengthen access controls, and build redundancy into critical systems.
