Abstract

A common language with consistency of meaning is a critical step in the evolution of a profession. Whilst the debate as to whether or not security should be considered a profession is ongoing there is no doubt that the wider community of professionals operating in the security domain are working towards achieving recognition of security as a profession. The concepts of defence in depth, protection in depth and security in depth have been used synonymously by different groups across the domain. These concepts represent the very foundation of effective security architecture are hierarchical in nature and have specific meaning. This paper through comparative analysis clearly defines the difference between and establishes the hierarchy such that a common understanding can be achieved.
