How do I keep a mySQL database secure?

Question

I\'m going to be implementing a PHP/mySQL setup to store credit card information.

Answer 1

MySQL, there is six easy steps you can do to secure your sensitive data.

Step 1: Remove wildcards in the grant tables

Step 2: Require the use of secure passwords

Note: Use the MySQL “--secure-auth” option to prevent the use of older, less secure MySQL password formats.

Step 3: Check the permissions of configuration files

Step 4: Encrypt client-server transmissions

Step 5: Disable remote access

Step 6: Actively monitor the MySQL access log
