What are the three main principles of information security known as the CIA Triad?

The three main principles of information security known as the CIA Triad are Confidentiality, Integrity, and Availability.

Confidentiality ensures that sensitive information is accessed only by authorized individuals and is protected from unauthorized access. This is critical in maintaining privacy and trust in systems that handle sensitive data.

Integrity refers to the accuracy and completeness of information, ensuring that data remains unaltered and trustworthy throughout its lifecycle. This principle is vital for maintaining the reliability of data, as any unauthorized modification can lead to disastrous consequences for decision-making and operations.

Availability means that information and resources are accessible to authorized users when needed. This principle highlights the importance of maintaining systems and networks to ensure they are operational and data is available to users in a timely manner.

Understanding and implementing the CIA Triad is essential for any professional in the field of information security, as it serves as a foundational model for developing and assessing security measures in organizations.
