Which aspect of information security focuses on the accuracy and trustworthiness of data?

The focus on the accuracy and trustworthiness of data is a key component of integrity in information security. Integrity ensures that information remains unaltered and accurate throughout its lifecycle, meaning that data cannot be modified by unauthorized individuals and that any changes are traceable. In practice, maintaining integrity involves various controls, like checksums, digital signatures, and auditing processes, to prevent tampering and to ensure data reliability. This is crucial for organizations that rely on accurate data for decision-making and operations since compromised integrity can lead to significant risks and consequences, such as loss of trust and faulty analytics.

Confidentiality, on the other hand, concerns keeping information secret and ensuring that only authorized users have access to sensitive data. Availability relates to ensuring that information and resources are accessible to authorized users when needed. Accountability involves tracking user actions and ensuring they can be held responsible for their behavior in the system. While all the aspects of information security are interconnected, integrity specifically emphasizes the authenticity and correctness of data.
