What is one aspect of Database Hardening?

Database hardening involves various practices to make a database system more secure against unauthorized access and potential vulnerabilities. Establishing different privilege levels for admin users is a crucial aspect of this process. By implementing varied privilege levels, an organization can ensure that users have the appropriate access based on their role within the system. This principle of least privilege minimizes risk by ensuring that users only have the permissions necessary to perform their jobs, thereby reducing the likelihood of accidental or malicious actions that could harm the data or compromise security.

For instance, a database administrator may need full access to manage the database, while a regular user may only require read access to certain datasets. By compartmentalizing access responsibilities, organizations can better manage data integrity and maintain tighter security controls.

Other options suggest methods that, while important, do not directly relate to the specific concept of privilege levels. For example, removing all administrative rights from all users is too extreme and might hinder necessary administrative functions. Increasing data redundancy does enhance data availability but does not directly address security aspects. Implementing encryption on data connections is a valid security measure but focuses on data protection in transit rather than user access controls. Therefore, the focus on establishing different privilege levels is the most relevant and effective component of database hardening.
