What is CIA (Confidentiality, integrity, and availability)?

CIA is intended to direct policies for data security within an organization. In the CIA, Confidentiality is identical to Confidentiality measures intended to prevent sensitive data from unauthorized access endeavors. Integrity includes managing the consistency, precision, and dependability of information over its entire lifecycle. The information must not be changed in transit, and steps must be taken to ensure information cannot be modified by unauthorized individuals. And Availability implies data should be reliably and readily accessible for authorized individuals.
