Digitalisation and the technological tools and systems often connected to the internet constitute serious risks for aviation cyber security. The Government Accountability Oice (GAO) has recently stated that air traic management and control (ATM/ATC) vulnerabilities could be used to undermine national security. Against this backdrop, several related questions arise: what technologies do air traic management and control systems rely on? Are these systems vulnerable? Which actors could pose a threat to these systems? Do they have the technological skills to conduct attacks that could compromise them?
