What entails data integrity in terms of cybersecurity?

Data integrity in cybersecurity refers to the accuracy, consistency, and trustworthiness of data throughout its lifecycle. The primary focus is on ensuring that data is not altered, corrupted, or otherwise manipulated without proper authorization. Attaining data integrity means implementing measures that prevent unauthorized modifications while allowing legitimate users to access and modify the data when needed.

This encompasses various practices, including user access controls, encryption, and validation checks, all aimed at safeguarding data against unauthorized changes. By establishing a secure system where data modifications are tracked and authorized, organizations can maintain the reliability and authenticity of their information.

On the other hand, the other choices relate to different aspects of cybersecurity but are not specifically about data integrity. Maintaining system uptime focuses more on availability, keeping shredded documents safe pertains to physical security and data disposal, and backing up data deals with data recovery rather than integrity itself. Thus, the emphasis on unauthorized alterations is what specifically underscores the concept of data integrity within cybersecurity.
