The TutsPlus.com site has posted the first part of a series wanting to help you secure your WordPress installation even more effectively. In part one of the series they cover some of the basics of securing the installation itself and the environment it lives in.

Do you think WordPress is secure? It's OK if you don't, because many people think WordPress is an insecure content management system, yet it's very far from the truth... at least today. [...] I'm sorry if you think the other way, but it doesn't. Frequent patches don't necessarily mean that a piece of software is poorly coded against security threats.

[...] The important thing here is to be responsive and preemptive, and that's something that WordPress excels at. [...] Yet, nothing is a hundred percent secure. We're living in times in which scientists are about to crack the code in our brains! Nothing is impenetrable, including our brains apparently, and WordPress is no exception. But the impossibility of 100% security doesn't mean we shouldn't go for 99.999%.

The remainder of the post is broken down into two different tips with the code/configuration changes and descriptions for what you need to update:

• Securing the .htaccess File
• Security Tricks for the wp-config.php File and Its Contents

The second item on that list also gets into some of the constant definitions and some advice on generating good "salt keys" for the configuration.
