The man who taught me what protection means
Douglas Finley fought in the Korean War. He came home with a Thai woman who would become my grandmother and a discipline that would become the family inheritance.
For the first eleven years of my life, I lived under one roof with my mother, my grandfather, and my grandmother. He took me everywhere. Even after my mother married and we moved out, I saw them every week.
What I learned from him in those years built the agency I run today.
He taught me that infrastructure is Swiss cheese. One wrong click on the wrong email. One USB drive plugged into the wrong machine. The whole system goes down. Most companies in his era focused on blacklisting, blocking what they already knew was bad. He pioneered whitelisting. Keep only what you need on the counter. Quarantine everything else.
He taught me that the most dangerous viruses behave like the common cold. They mutate. They change their code with every infection. The only way to stop them is a system designed to recognize what should be there, not chase what should not.
In 1997, he turned that discipline into a company. Naknan Inc., founded in Houston, with one mission. Make new internet safer.
His earlier engineering work supported NASA's Apollo-Soyuz mission in 1975 and the Viking Mars mission in 1977. By the early 2000s, Naknan's Security Assistant product was running on systems at NASA and at U.S. power plants. By 2011, the Department of Homeland Security was using Naknan in cybersecurity training.
He passed on February 7, 2024. The lineage he started runs through every coverage I write.
