Securing your SQL Server Instances

image

SQL Server and Azure SQL Database are two of the most complete and powerful data platforms in the world. With SQL Server and Azure SQL Database you can store and organize structured, semi-structured and unstructured data and transform it into useful knowledge via complex transformations and sophisticated processing.

The above, make it a necessity for every Organization to secure and harden their SQL Server instances up to the maximum possible level, without of course affecting the operation of the supported systems.

 

For this purpose, there are published security standards and guidelines by well-respected security organizations which can be used for securing your SQL Server instances. This is however a complex process, based on which you need to thoroughly assess every single SQL Server instance you have against a list of security factors. Moreover, it is a process that needs to be constantly repeated as databases and SQL Server instances are not static. They change. New databases are added, new features might be enabled and so on.

Securing SQL Server is not just a matter of securing its surface area. A proper hardening process involves securing the following as well:

  • Physical environment (i.e. data room)
  • Operating system
  • Network
  • Client applications

All the above require well-balanced teamwork and coordination in order to ensure that all, or at least the majority of possible vulnerabilities has been mitigated.

Now, when it comes to securing your SQL Server instances, you can check a powerful software tool which can help you through the process of eliminating vulnerabilities that might have to do with the setup of your SQL Server instances and databases. This tool is DBA Security Advisor.
