Hi there! I'm new to MySQL. What security measures should I take to ensure security of my databases? Any keywords? For instance, often times when logging into the DB, you must enter the user and pwd to gain access. How can I make that more secure? It's obviously in plain text... Any suggestions? Thanks!

Put them behind a firewall on an encrypted drive. Let no one access the server except your application (using MySQL grants). If you need access from outside, do it over VPN. And there are tons of other security measures which you may find here: http://lmgtfy.com/?q=mysql+security

Interesting, thanks for sharing!
