Which pillar is most concerned with data being stored safely and not prone to loss?

The pillar most concerned with data being stored safely and not prone to loss is Integrity. Integrity in information security focuses on maintaining the accuracy and consistency of data over its entire lifecycle. This means implementing measures to prevent unauthorized modifications and ensuring that the data remains identical to its original state, protecting it from accidental or malicious changes. When data integrity is upheld, it guarantees that the information remains accurate and trustworthy, which is crucial for any system handling sensitive or critical data.

While the other pillars—confidentiality, availability, and utility—address important aspects of data management, they do not specifically focus on the safety and permanence of the data itself. Confidentiality pertains to keeping information private and ensuring that only authorized individuals have access to it. Availability is concerned with ensuring that data is accessible and usable when needed. Utility focuses on the usefulness of data, which is related to its operational function rather than its preservation. Thus, integrity is the most appropriate choice regarding safeguarding data from loss or corruption.
