What are the three pillars of the CIA triad?

The three pillars of the CIA triad are Confidentiality, Integrity, and Availability. This model is fundamental in the field of information security and outlines the core objectives that organizations aim to ensure when protecting data and information systems.

Confidentiality refers to safeguarding information from unauthorized access and disclosure. This means ensuring that sensitive data is only accessible to those who have the appropriate permissions. Techniques such as encryption, access controls, and authentication mechanisms are employed to maintain confidentiality.

Integrity pertains to the accuracy and reliability of data. This involves ensuring that information is not altered improperly, whether by accident or malicious intent. Measures such as hashing, checksums, and version control help maintain the integrity of data, allowing organizations to trust the information they handle.

Availability ensures that information and resources are accessible to authorized users when needed. This encompasses maintaining the uptime of systems, performing regular maintenance, and implementing disaster recovery plans to ensure that services remain operational, even in the face of failures or attacks.

The other choices do not accurately represent the established concepts of the CIA triad. The terms in those options either replace or incorrectly describe the essential elements of information security covered by the original triad. Therefore, the most accurate and widely accepted answer remains Confidentiality, Integrity, and Availability.
