What are the three pillars of information security commonly known as?

The three pillars of information security are commonly referred to as Confidentiality, Integrity, and Availability, often abbreviated as CIA. This framework is foundational to understanding the goals of information security.

Confidentiality ensures that sensitive information is accessible only to those authorized to have access, thereby protecting personal data and proprietary information from unauthorized disclosure. This is critical in preventing data breaches and safeguarding privacy.

Integrity focuses on maintaining the accuracy and consistency of data over its lifecycle. This means that data cannot be altered or deleted by unauthorized individuals, ensuring that it remains trustworthy and reliable. Integrity is essential to maintain the authenticity of data and trust in information systems.

Availability ensures that information and resources are accessible to authorized users when needed. This involves ensuring that systems are up and running, and that data is retrievable without unnecessary delays, which is crucial for operational effectiveness and business continuity.

Together, these three pillars form a comprehensive approach to information security, addressing the fundamental aspects necessary to protect and manage information effectively in any organization. The choices related to authentication, protection, and risk management are important concepts in security but do not encompass the core principles represented by the CIA triad.
