When it comes to database administration, the first order of business is to keep each server secure. Every experienced DBA would agree that no server should operate without adequate security measures. It is for this reason that the language used in most databases is SQL, as it is designed to store data securely. SQL is downright impressive given the security features it has.
The problem is that some DBAs rely solely on these security features, and this shouldn’t be the case. Bad security practices are enough to compromise a server, regardless if the language it uses is secure. For this reason, aspiring DBAs have to be aware of some commonly overlooked mistakes in SQL server security. Here are three of them:
Any organisation that uses a computer needs a backup of all the data they have. It shouldn’t stop there, though. The backup itself should be secure with encryption. Surprisingly, this is one mistake many DBAs are guilty of. Simply because there’s a backup doesn’t mean everything is fine. You have to think about the potential scenario of the backup being compromised. It’s unlikely to happen, but being prepared for the worst is better than being caught off-guard.
Sometimes, DBAs forget to remove users that should no longer have access to certain SQL functions. This could lead to problematic system changes and other behaviour that may compromise information. Make sure that backup folders are accessible only to those who truly need it. If you need further SQL support, DBA Services recommend hiring experts and not just somebody who offers SQL services for a too-good-to-be-true price.
As much as possible, you should only run SQL servers in local accounts that have minimal privileges. This ensures that there are no unwanted changes made in the system. As long as the service has full permissions to read and write activities for data, log, and backup directories, most functions should be fine.
Even the slightest opening can crack open the strongest of armour. Treat the server as an armour that safeguards your data and make sure that there are no cracks in it for any potential compromise.
