Which statement best describes auditing in a database security model?

Auditing in a database security model primarily involves tracking actions taken within the database. This includes monitoring user activities, recording changes made to data, and capturing who accessed what information and when. The purpose of auditing is to create a detailed record that can help organizations understand how their data is being used, identify potential security breaches, and ensure compliance with regulations.

By continuously logging and reviewing these activities, database administrators can gain insights into user behavior and detect anomalies that may indicate security issues, ensuring a more secure and trustworthy environment for sensitive information. This tracking capability is foundational in establishing accountability and enhancing the overall security posture of a database system.

The other options, while related to database management, do not accurately define the role of auditing within a security model. For instance, preventing unauthorized access is a function of access control measures rather than auditing. Enhancing database performance is typically associated with optimization techniques rather than tracking actions. Similarly, creating backups is a separate process focused on data recovery, distinct from the auditing of user actions and behaviors.
