Most modern organizations rely heavily on the information stored in their database systems. From sales transactions to human resources records, mission- critical, sensitive data is tracked within these systems. From the standpoint of security, it is very important that business and systems administrators take the proper precautions to ensure that these systems and applications are as secure as possible. You wouldn’t want a junior-level database administrator to be able to access information that only the executive team should see; but you also wouldn’t want to prevent your staff from doing their jobs. As with all security implementations, the key is to find a balance between security and usability.
