The concept of the "CIA triad" is fundamental in understanding the objectives of cryptography and secure systems. It encapsulates the three essential pillars that every such system strives to achieve.

Confidentiality, the first element of the CIA triad, refers to the ability to ensure that only authorized individuals or systems can access sensitive information. This is crucial in protecting sensitive data from unauthorized disclosure.

The second element, integrity, pertains to the assurance that information has not been altered or tampered with in an unauthorized manner. It ensures that the data remains accurate and reliable.

Availability, the third and final element of the CIA triad, focuses on ensuring that authorized users have timely access to the information they need. This means that systems must be operational and accessible when required.
