Most Important Security Tip - Use a Good Web Host

Using a good web host is the most important security tip to keep in mind when you decide to create a web site.

Use a reliable web host with a good track record of support. Make sure you use a host that keeps their servers as secure as possible and the basic server scripts (PHP, MySQL, their control panel, phpMyAdmin, etc) updated to the latest stable releases.

Some hosts update to beta and RC versions - I keep clear of these as updating before a release becomes stable means the possibility of bugs and vulnerabilities exist.

Remember, if your server space is vulnerable, hackers can get in. Many security breaches that get reported on the Mambo forums have nothing to do with Mambo security and everything to do with server security and the other scripts that are run on that server. Building a house on crumbling bricks is not usually a good idea - nor is it a good idea to invest your time and money on building a web site if the foundations of that site (ie. the server) are not sound.
