Question How to make my MySQL Server more secure ?

[capedech]

Hi,
How to make my MySQL Server more secure beside putting password on it.

From :
MySqlConnectionString = "Database=dbtest;hostname=localhost;userid=admin;"

Become :
MySqlConnectionString = "Database=dbtest;hostname=localhost;userid=admin;password=gagigugego;"

I am making an application using MySQL as the database, using WAMP.
Is it already secure only with that password, or need more methods to secure the database.

Thanks in Advance.

Regards,
