What does CIA stand for in the context of information security?

In the context of information security, CIA stands for Confidentiality, Integrity, and Availability. This model is fundamental to understanding how to protect and manage information systems effectively.

Confidentiality ensures that sensitive information is only accessible to those who are authorized to see it. This is critical in preventing unauthorized access and data breaches.

Integrity involves maintaining the accuracy and reliability of data throughout its lifecycle. It ensures that information cannot be altered or deleted by unauthorized individuals and that it remains consistent and trustworthy.

Availability ensures that data and systems are accessible to authorized users when needed. This aspect of the CIA triad highlights the importance of having systems that are resilient to disruptions, whether due to technical failures or cyber attacks.

The other options provide terms that relate to security concepts, but they do not encapsulate the core principles of the CIA triad, which is essential for a well-rounded approach to information security. The focus of CIA is comprehensive, covering all critical aspects necessary for protecting information systems against various threats.
