What Is the CIA Triad in Cybersecurity and Why Does It Matter?

CIA Triad concept showing confidentiality, integrity, and availability in cybersecurity
The CIA Triad is a fundamental concept in cybersecurity that stands for Confidentiality, Integrity, and Availability. These three principles form the foundation of any robust security strategy.

Confidentiality

Confidentiality involves keeping sensitive information private, such as customer data. This is achieved by protecting your data and environment against unauthorised access through encryption, access controls, and strong authentication.

Integrity

Integrity ensures that data remains accurate and unaltered. For example, when you send an email, you want to be confident that the message received is exactly what you sent, and stored data remains unchanged.

Availability

Availability means that data is accessible to those who need it when they need it. While securing data is critical, it must also be available to employees and systems that require access to perform their functions.
