What does the term 'integrity' ensure within a network system?

The term 'integrity' within a network system primarily refers to the accuracy and consistency of data. It ensures that information and programs are altered or changed only in a specified and authorized manner. This means that there are controls and procedures in place that prevent unauthorized access or modifications to the data, which helps maintain its reliability and authenticity over time.

Integrity is crucial in preventing data breaches and corruption, as it safeguards against both accidental and intentional tampering. In secure systems, this is often enforced through access controls, validation checks, and auditing processes that ensure any changes to the data are made correctly and legally.

Considering the other options, while data storage correctness relates to integrity, it does not encompass the broader aspect of authorized change which is central to the concept of integrity. Network accessibility pertains to user access levels rather than data accuracy or authority, and minimum uptime focuses on system availability rather than safeguarding data. Thus, the emphasis on authorized changes is what correctly reflects the concept of integrity in network systems.
