The aim of this course is to provide an introduction to the theory and concepts of security, as applied to computer systems. The course builds on the earlier course on system administration, where security was discussed from a practical viewpoint. In this course, a deeper understanding of the principles and examples of security will be explored. In addition we shall be looking at common problems in software design, which lead to insecurity.
