Alan DeKok's story shows an uncommon professional trajectory. He started in nuclear physics and veered into network security, where he became a central figure. He is the co-founder and leader of the FreeRADIUS project, an open source authentication server that verifies identities in global networks, from ISPs to Eduroam. His project, started as a hobby in the 90s, is now critical infrastructure.
Technical Evolution and the RADIUS Standard ⚙️
FreeRADIUS implements the RADIUS protocol, managing user authentication, authorization, and accounting in networks. DeKok has not only maintained the server for nearly three decades, adapting it to new technologies like 802.1X and EAP, but has also driven standards in the IETF. His work has been key to keeping the original 90s protocol viable in modern high-security environments.
When Your 90s Hobby Becomes Half the World's Login 🌐
Imagine a project you started for fun ends up being the gateway to the internet for universities, airports, and companies. Every time someone complains that the Wi-Fi isn't working on campus, deep down they're interacting with your code from twenty years ago. It's the dream of every developer: create something so useful that people don't even know it exists, until it fails.
