The Confidentiality, Integrity and Availability Triad

The Confidentiality, Integrity and Availability Triad-

Three of the primary concepts in information security are confidentiality, integrity, and availability, commonly known as the confidentiality, integrity, and availability (CIA) triad. The CIA triad gives us a model by which  we can  think  about  and discuss  security  concepts,  and  tends  to be very focused on security, as it pertains  to data. The common notation for confidentiality, integrity, and availability is CIA. In certain materials, largely those developed by ISC2 we may see this rearranged slightly as CAI. No change to the concepts is implied in this rearrangement, but it can be confusing for those who do not know about it in advance. We may also see the CIA concepts expressed in their negative forms: i.e disclosure, alteration, and denial (DAD).
