What is the most effective control for enforcing accountability among users accessing sensitive database information?

Implementing a log management process is crucial for enforcing accountability among users who access sensitive database information. This approach provides a systematic way to monitor and record user activity, which is essential for auditing and compliance purposes. By maintaining detailed logs of who accessed what data, when, and what actions were taken, organizations can effectively trace any unauthorized access or changes to sensitive information.

This accountability mechanism not only helps in identifying potential breaches but also serves as a deterrent to inappropriate behavior, as users are aware that their actions are being tracked. Additionally, log data can be analyzed to identify irregular patterns that may indicate security incidents or misuse of sensitive information, thus enhancing overall security posture.

In contrast, while two-factor authentication adds a layer of security during the login process to ensure that only authorized users can access the system, it does not provide a comprehensive audit trail of user activities. Using table views to restrict how sensitive data is presented can minimize exposure but does not inherently enforce accountability for actions taken on that data. Separating database and application servers increases security architecture but does little to directly enhance accountability in terms of user actions within the database.
