One of the more important duties of a DBA is to make sure that their databases and the data is secure. In this post we’ll be looking at two utilities to increase the security of your server, the Windows Firewall and an antivirus software. Like with about everything else related to servers, you can’t just switch these on (well, you could, but…) and forget about them to get the best possible experience. They need to be properly configured for servers running Microsoft SQL Server. If you’re a DBA you might not be doing the configuration yourself, but you still need to tell your Windows administrators what they need to do.
