In a cybersecurity context, what does 'integrity' primarily refer to?

In a cybersecurity context, 'integrity' primarily refers to maintaining the accuracy and reliability of data. This means ensuring that data is not altered or tampered with in unauthorized ways. When integrity is preserved, users can trust that the data they are accessing is complete and accurate, enabling them to make informed decisions based on that information. Protecting data integrity is crucial in preventing unauthorized modifications, whether accidental or malicious, and entails implementing measures like checksums, validation protocols, and access controls.

In contrast, the other choices focus on different aspects of cybersecurity. The ability to keep systems running pertains more to system availability, while protecting user privacy and data confidentiality relates to ensuring that sensitive information is not disclosed to unauthorized individuals. Limiting data access to a select group is also part of confidentiality and access control rather than directly addressing data integrity. Each of these elements is important in the overall context of cybersecurity but does not capture the essence of integrity as it specifically relates to data accuracy and reliability.
