If your website is built on the WordPress platform then here are some tips that will help you keep it nice and secure.
1. Change table prefix in
wp-config.php to random generated. This must be done before you install WordPress unless you know how to edit your database.
wp-includes by adding the following to your
.htaccess file – note that this should go outside
# BEGIN WordPress and
# END WordPress tags as WP can overwrite anything within those.
# Block the include-only files. This adds more security to your WordPress install. RewriteEngine On RewriteBase / RewriteRule ^wp-admin/includes/ - [F,L] RewriteRule !^wp-includes/ - [S=3] RewriteRule ^wp-includes/[^/]+.php$ - [F,L] RewriteRule ^wp-includes/js/tinymce/langs/.+.php - [F,L] RewriteRule ^wp-includes/theme-compat/ - [F,L] # BEGIN WordPress
wp-config.php by moving it outside the site. You can move the
wp-config.php file to the directory above your WordPress install. This means for a site installed in the root of your webspace, you can store
wp-config.php outside the
4. Disable file editing within the admin area by adding the following to
/** Disable admin editing of files. This adds more security to your WordPress install. */ define('DISALLOW_FILE_EDIT', true);
5. Make ‘admin’ username something other than ‘admin’. This sounds obvious but I’ve lost count of how many times I have been given the login creadentials of ‘admin’ and ‘password’. There are loads of strong password generators out there that can help you with this. Just make sure you make a note of them in a secure place.
6. Don’t post as admin, post as contributor and publish with admin. Again, this sounds obvious but if you post as your admin then you have just given away your username to the public unless you have your display name set to something different.
7. Use strong passwords. See number 5.
General file / folder permission notes:
The root WordPress directory: all files should be writable only by your user account, except
.htaccess if you want WordPress to automatically generate rewrite rules for you.
The WordPress administration area: all files should be writable only by your user account.
The bulk of WordPress application logic: all files should be writable only by your user account.
User-supplied content: intended to be completely writable by all users (owner/user, group, and public).
/wp-content/ you will find:
Theme files. If you want to use the built-in theme editor, all files need to be group writable. If you do not want to use the built-in theme editor, all files can be writable only by your user account.
Plugin files: all files should be writable only by your user account.
Other directories that may be present with
/wp-content/ should be documented by whichever plugin or theme requires them. Permissions may vary.
