UNIT 4 – BASIC PRINCIPLES
Key concepts
For over twenty years, information security has held confidentiality, integrity and availability (known as the CIA triad) to be the core principles of information security.
There is continuous debate about extending this classic trio. Other principles such as Accountability have sometimes been proposed for addition - it has been pointed out that issues such as Non-Repudiation do not fit well within the three core concepts, and as regulation of computer systems has increased (particularly amongst the Western nations) Legality is becoming a key consideration for practical security installations.
In 2002, Donn Parker proposed an alternative model for the classic CIA triad that he called the six atomic elements of information. The elements are confidentiality, possession, integrity, authenticity, availability, and utility. The merits of the Parkerian hexad are a subject of debate amongst security professionals.
