Technical Details

what runs on :8600

ASTERIX is a binary application data format rather than a complete session protocol. Implementations commonly send ASTERIX blocks over UDP for real-time feeds, with TCP also used where a reliable stream is required; the format itself provides category, length, field-presence, and data-item structures, including FSPEC-driven records. It does not mandate a universal handshake, encryption scheme, or transport default beyond the assigned use of TCP and UDP port 8600.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

security overview

ASTERIX traffic is normally unencrypted and unauthenticated at the format level. Internet exposure can disclose aircraft positions and operational surveillance data, while an attacker able to inject or alter traffic could corrupt tracking inputs; restrict the port to trusted sensor and ATM networks and protect it with network controls or secure tunnels.
