What are the three pillars of information security?

The three pillars of information security are confidentiality, integrity, and availability, often referred to as the CIA triad.

Confidentiality ensures that sensitive information is accessed only by authorized individuals, protecting data from unauthorized disclosure. This is critical for maintaining trust and securing personal and organizational information.

Integrity involves maintaining the accuracy and consistency of data over its entire lifecycle. This means that the information cannot be altered in an unauthorized manner, ensuring that users can trust the data they are working with. It is essential for making informed decisions based on accurate information.

Availability ensures that information and resources are accessible to authorized users when needed. This pillar is crucial for ensuring operational continuity and minimizing downtime, which can have significant implications for businesses and services.

Together, these three components create a comprehensive framework for protecting information systems and ensuring that data is handled securely throughout its lifecycle.
