The US Government Accountability Office’s July 2026 review of FAA and TSA cybersecurity efforts found that aviation’s interconnected systems face vulnerabilities including insecure operational technology, poor separation of IT and OT networks and insecure supply chains.

Bridewell found that 60% of respondents said they were extremely concerned about cyber threats to airport operational infrastructure and supply-chain partners.

The aviation ecosystem makes isolation difficult. Airlines connect with airports, ground handlers, manufacturers, maintenance providers, technology companies and numerous other suppliers.

Bridewell warns that a compromised system can potentially spread disruption through this connected network, affecting airports, airlines and handlers.
