If you are running Microsoft SQL Server you probably aware of brute-force attacks on SA account.
Almost every SQL server connected to the Internet is under constant attack.
Once a hacker has access to a SA (DBA) account, or even a normal user account,
it can get full access to the file system on a server, or even
to the files on the network to which it is connected.
If your SQL server accepts remote connections,
System Event Log may contain thousands of entries like below:
Login failed for user 'sa' error 18456.
This means that someone is trying to get access to your server.
Brute-force attacks may also abuse your server resources (CPU, RAM and Bandwidth).
allows you to protect your MS SQL Server from brute-force attacks.
It monitors the EventLog and detects failed login attempts.
If the number of failed login attempts from a single IP address reaches a set limit (three by default),
the attacker's IP address will be blocked!
