What are the three main pillars of security?

The three main pillars of security are Confidentiality, Integrity, and Availability, often referred to as the CIA triad.

Confidentiality ensures that information is accessible only to those authorized to have access. It aims to protect sensitive information from unauthorized disclosure, employing various measures such as encryption and access controls.

Integrity refers to the accuracy and reliability of data, ensuring that it is not altered in an unauthorized way. This pillar maintains the trustworthiness of information, using checksums, hashing, and validation techniques to detect unauthorized changes.

Availability ensures that information and resources are accessible to authorized users when needed. This aspect of security involves implementing measures to prevent downtime and ensure systems are operational, including redundancy, failover systems, and regular updates.

By focusing on these three pillars, organizations can create a robust security framework that protects their information assets effectively.
