The Parkerian hexad is a set of six elements of information security proposed by Donn B. Parker, renowned security consultant and writer. The term was coined by M. E. Kabay. The Parkerian hexad adds three additional attributes to the three classic security attributes of the CIA triad (confidentiality, integrity, availability).
The Parkerian Hexad attributes are the following:
- Confidentiality
- Possession or Control
- Integrity
- Authenticity
- Availability
- Utility
These attributes of information are atomic in that they are not broken down into further constituents; they are non-overlapping in that they refer to unique aspects of information. Any information security breach can be described as affecting one or more of these fundamental attributes of information.
I think I don’t require to provide the explanation of C-I-A here. Let’s look at the other attributes.
