SQL Server Audit This tool allows you to test the password vulnerability of the „sa‟ account (i.e. root administrator), and any other SQL user accounts configured on the SQL Server. During the audit process, this tool will perform dictionary attacks on the SQL server accounts using the credentials specified in the „passwords.txt‟ dictionary file. However, you can also direct the SQL Server Audit tool to use other dictionary files. You can also customize your dictionary file by adding new passwords to the default list. To perform a security audit on a particular Microsoft SQL server installation: 1. Launch GFI LANguard management console from Start ► Programs ► GFI LANguard 2011 ► GFI LANguard 2011. 2. Click Utilities tab and select SQL Server Audit in the left pane under Tools.
