Trust crosses a number of departments, disciplines, and areas. To aid students in identifying appropriate study sequences in trust, ITI personnel have grouped courses into the following roadmaps. A roadmap is a description of a particular focus area available to students, including descriptions of especially relevant courses. Each block in the below chart identifies a trust focus. Arrows show how different areas build on each other. See roadmaps for Foundations, Security, Dependability, Trust Assessment, and Applications.
