The UK Civil Aviation Authority (CAA) is the nation's independent aviation regulator, setting and enforcing safety and compliance standards across all civil aviation activities. Its remit spans commercial airlines, drone operations, aerospace, and spaceflight - domains where a security breach isn't just a data problem, it's a kinetic one. The attack surface is vast: air traffic systems, consumer financial protection schemes, and aircraft registration databases all fall under the CAA's operational scope.
Key systems include G-INFO, the comprehensive UK aircraft registration database, and the ATOL protection schemes that safeguard consumer funds in the air travel market. These aren't theoretical targets; they're critical national infrastructure holding sensitive data on aircraft ownership, operator compliance, and financial transactions. Regulatory standards are codified through Civil Aviation Publications (CAPs), which define the compliance frameworks the entire UK aviation industry must meet.
The CAA's technical frontier is expanding into domains with significant security implications: artificial intelligence applications in aviation systems, beyond visual line of sight (BVLOS) drone operations requiring robust command-and-control links, and hydrogen propulsion technology. Each introduces new threat vectors - from adversarial ML attacks on safety-critical AI to the security of unmanned aircraft communication protocols. The work operates at the intersection of operational technology, critical infrastructure defense, and regulatory enforcement across the UK.
