Re: How to prevent brute force attacks ?

Do you need to provide network connections?? If all your databases are accessed locally you can simply disable mysql networking using skip-networking. You might also want to consider blocking port 3306 on the firewall as well.

If you really need to have networking enabled on MySQL then I would suggest you restrict access to 3306 using the firewall to only those IP addresses which need to reach the MySQL server from the outside. You might also want to consider using SSL to encrypt the data being sent.
