Confidentiality, Integrity and Availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization.

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.
