Over the years I have developed many mind maps when writing articles, and I have also used them as a way of collecting information and organising it. I was a fan of Freemind, and with effort, I uploaded some maps to the Freemind gallery. Later I switched to Freeplane but it still did not give me a simple way to share maps. I have now taken out a membership at MindMeister as the site can read and publish mind maps in a collection of formats. You can find about 20 or so maps here, mainly from past articles, with new ones to follow. There is a large map on Trends & Analysis from 2008, giving you some idea how complex and from which sources you need to collect information to get a handle on IT Security.
