What are the three main objectives of information security?

The objective of achieving confidentiality, integrity, and availability, often referred to as the CIA triad, forms the foundational principles of information security.

Confidentiality ensures that sensitive information is accessed only by authorized individuals, protecting data from unauthorized disclosure. This is critical in preventing data breaches and maintaining the trust of stakeholders.

Integrity involves safeguarding the accuracy and completeness of information. It is essential for ensuring that data is reliable and has not been altered by unauthorized means. This aspect of information security is vital for maintaining the authenticity and accuracy of information used in decision-making processes.

Availability ensures that information and systems are accessible to authorized users when needed. This aspect is crucial for operational continuity, enabling organizations to maintain productivity and service delivery without interruptions.

This triad of objectives works synergistically to protect an organization’s information assets, helping to mitigate risks associated with data breaches, loss of data integrity, or downtime. The other choices presented do not fully encompass this well-established triad, which is essential in the field of information security.
