Security is too often merely an illusion, an illusion sometimes made even worse when gullibility, naivette, or ignorance come into play." They go on to say that "security is not a technology problem — it's a people and management problem." My experience is that the "technology factor" and the "people factor" go hand in hand; you need to address both issues to succeed.

This chapter overviews the issues associated with security access control within your system.
