The scenario describes a situation where the company's IT team discovered a discrepancy in network logs, with some logs related to user access and activities being incomplete. This situation points to a violation of the information security principle of integrity.

Integrity in information security refers to the accuracy and completeness of data and information. It ensures that data is not altered or tampered with and remains consistent and accurate. Incomplete network logs suggest that data might have been manipulated, deleted, or not properly recorded, compromising the integrity of the logging system.

Maintaining log integrity is crucial for security monitoring, forensic analysis, and compliance with regulatory requirements. When logs are incomplete, it becomes challenging to detect unauthorized access, investigate incidents, and maintain trust in the system’s accuracy.
