confidentiality, integrity, and availability (CIA triad)

Confidentiality, integrity and availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization.
The model is also sometimes referred to as the AIC triad (availability, integrity and confidentiality) to avoid confusion with the Central Intelligence Agency.
The elements of the triad are considered the three most crucial components of security.
In this context, confidentiality is a set of rules that limits access to information, integrity is the assurance that the information is trustworthy and accurate, and availability is a guarantee of reliable access to the information by authorized people.
