IUUC Xeno's goal was to create a taxonomy for security topics. If you will take a look here: https://ost2.fyi/System%20Security.html You can find a bigger plan showing the relation between various numbers of courses. Of course, we can only create minimal courses (compared to those taught in universities) about coreboot or UEFI, but in the long run, we should put together one of the most comprehensive firmware training with open and free access for everyone. You can read more about that motivation on other pages of https://ost2.fyi. Security is a broad topic covering various aspects. Please let us know if you have ideas about improving the used taxonomy since it takes enormous effort to put all security topics on the chart and build a map for students that will provide a seamless learning experience.
