What is one example of what an audit trail monitors in an information system?

An audit trail serves as a crucial component of an information system, particularly in ensuring data integrity and security. One primary function of an audit trail is to monitor unauthorized access to sensitive information. This involves keeping a detailed record of who accessed the system, when they accessed it, and what actions they performed. By tracking this information, organizations can detect potential security breaches or inappropriate access, thus helping to protect patient information and maintain compliance with regulations such as HIPAA.

Monitoring unauthorized access is vital for identifying malicious activities or breaches in security protocols. It enables organizations to respond swiftly to any detected anomalies and reinforces accountability among users. Additionally, analyzing audit trails can assist in refining access policies and improving overall system security.

In contrast, while data entry errors, system downtime, and file storage capabilities are important aspects of information systems management, they either fall outside the primary focus of audit trails or are monitored through other mechanisms. Audit trails are specifically designed for tracking user interactions and changes made within the system, making them essential for identifying and addressing unauthorized access incidents effectively.
