Airport security is a lot like cybersecurity. Each is a cumbersome process aimed at protecting valuable assets. Both involve detection and response. In both airport and cyber security, the approach is to find threats that have made it inside the exterior walls — e.g., detect threats via x-raying luggage at the airport or by uncovering zero-day vulnerabilities in application code in production. Then, respond by blocking the threat, be it by removing forbidden materials from luggage or blocking exploitation of a web application vulnerability bysurrounding dangerous functions with trust boundaries.

Application Detection and Response (ADR) for cybersecurity is similar to airport security in that both require detecting and responding to threats that have penetrated external defenses. In cybersecurity, this involves finding and mitigating threats like zero-day vulnerabilities within application code, similar to how airport security scans luggage to remove forbidden items. Effective threat response in cybersecurity includes measures such as surrounding dangerous functions with trust boundaries.
