The following basic themes unify the discussion: a) Principles: although the scope of it is broad, there are a number of basic principles that appear repeatedly as themes and that unify this field. b) Design approaches: it examines alternative approaches to meeting specific computer security requirements. c) Standards: have come to assume an increasingly important, indeed dominant, role in this field. d) Real-world examples: a number of the chapters include a section that shows the practical application of that chapter's principles in a real-world environment.
