For those of us in the US, it’s our day of independence. A day that stands for FREEDOM and happiness. Fireworks will light up the sky tonight! For the rest of the world it’s another random day in July. But don’t worry everyone can celebrate “Free”dom with this new community tool.
I’ve spent the last couple years writing, improving, and using this tool at my customers. This health check now has more than 300 data points and even pulls out bad practice and concerns from your procs. As of today, I gift it to the community. #SQLFAMILY

This is a very simple script which allows you to find any SQL Server authenticated accounts that have either a blank password or password that matches the user name and allow you to take action to remove the threat immediately.Read More »

In June of 2015, I added two tools to the Microsoft Technet Gallery which can be used to help achieve better SQL Server security. The first tool is a T-SQL script designed to reveal any SQL Server authenticated logins have either a blank password or a password matching the login name. The second is a console application designed to demonstrate a brute force attack.
