What are the three main principles of the CIA triad in security?

The three main principles of the CIA triad in security are Confidentiality, Integrity, and Availability.

Confidentiality ensures that sensitive information is accessed only by authorized individuals, preventing unauthorized access and breaches of privacy. This principle is foundational in protecting personal and organizational data from exposure to individuals who should not have access.

Integrity refers to the accuracy and reliability of data. It ensures that information is not altered or tampered with in an unauthorized manner, maintaining its trustworthiness. This is critical in environments where data is subject to various forms of input or modification that could adversely affect its authenticity.

Availability ensures that information and resources are accessible to authorized users when needed. This principle highlights the importance of maintaining system uptime and ensuring that services are operational and reachable.

Together, these three principles work to create a robust security framework that protects data from various threats and vulnerabilities, making them essential components of any comprehensive security strategy.
