Security Hardening of EMQX in Production (Part 2): Infrastructure and Erlang VMThis second article focuses on the foundation beneath EMQX: the Linux kernel, network stack, and Erlang VM. If Part 1 explained why security and reliability converge for a stateful MQTT broker, this part shows where that convergence actually bites in production: file descriptors, TCP behavior under load, firewall rules, and Erlang distribution security.
