The Ugly Side of SQL Server Logins

Jeff Iannucci continues a series on security in SQL Server:

SQL Server logins are often necessary, like the sa login, but be aware they present a particular set of vulnerability issues. Their lack of multifactor authentication, their susceptibility to brute force attacks, and the dumb passwords folks give SQL Server logins make them a prime target for hackers.

Read on to learn more about these three issues. Jeff also includes a note about a built-in function that lets you compare the hashed passwords in your systems versus a specific password, with the idea that you can at least find if people are using some of the most common passwords.
