Although I've always had a diverse set of interests, it was JJ Thompson of Rook Consulting who really showed me how valuable it is to have a broad range of skill for a computer security career, and who coined the term "Renaissance security professional". Computer security needs to be more than just about technology. There is no "magic box" (hardware or software) that will make our networks impenetrable. Computer security professionals need to have an understanding of business so that we can converse with people outside our fields to show them why we're trying to make whatever change we're doing, rather than just trying to use fear, uncertainty and doubt (FUD) to make our arguments. We need to understand psychology and human behavior so that our security policies are realistic, rather than trying to demand people remember impossibly complex passwords without writing them down. An understanding of military history can inform better strategies for network defense. Besides these examples, a broad-based skill set makes one better prepared for whatever comes in life, and makes for a better person.
This is what I intend to do, and this blog will be part of that effort.
