Every piece of software has security issues and SQL Server is no exception. Because this is server product and many DBAs do not manage the external security for their systems, I often find unpatched servers with vulernabilities. Now there are not too many alerts for SQL Server, but there are a few. Below are links to patches as well as other resources for keeping informed.
I will continue to update this area as new alerts are released. Please check back periodically for updates. I will also be adding some articles on SQL Security and best practices that should be followed.
