- For router users, there is nothing to do, just do not open these ports!
- For non-router users, just make sure in your Firewall List, the MMSQL application has Access Deny for the 3 sets of ports 1431, 1433, 1434
You can use also SQL SHIELD to protect your MS-SQL a bit more.
Also using another username than 'sa' will save you from being hacked time and time again, just make sure you edit the properties of the new User ID, make him owner of your databases.
