What is the purpose of personnel monitoring in a system?

The purpose of personnel monitoring in a system primarily revolves around overseeing the activities of system users and administrators. This practice is critical for ensuring the security, integrity, and compliance of information systems. By systematically tracking user activities, organizations can not only identify unauthorized access and potential misconduct but also enhance accountability among employees. This monitoring helps detect and respond to anomalies, ensuring that users are adhering to established security protocols and policies.

In the context of compliance, effective personnel monitoring is vital in demonstrating that an organization is proactively managing its risks and safeguarding sensitive data. It reinforces the establishment of a secure environment where users operate within defined roles and responsibilities, thereby mitigating potential threats and vulnerabilities linked not just to external factors but also to internal actors.

The other options, while relevant to system management, do not align with the primary aim of personnel monitoring. Measuring system uptime, auditing financial transactions, and tracking hardware performance addresses specific operational aspects rather than focusing on user behavior and activity oversight, which is at the core of personnel monitoring.
