What aspect of information security does "Integrity" involve?

Integrity in information security is fundamentally concerned with maintaining the accuracy and completeness of data. This means that the data must remain unaltered, consistent, and reliable over time. Any unauthorized alterations or corruption of data can compromise its integrity, leading to inaccuracies that can have detrimental effects on decision-making processes or operational effectiveness.

By focusing on ensuring data integrity, organizations implement controls that prevent unauthorized modifications and facilitate the detection and correction of errors or changes that may occur. This includes measures such as checksums, hash functions, and data validation rules, which help maintain the trustworthiness of data.

Other aspects of information security focus on different principles. For instance, preventing unauthorized access relates to confidentiality, while protecting system availability deals with ensuring that information systems are operational and accessible when required. Integrity specifically emphasizes the quality and trustworthiness of the data itself.
