WordPress Lockdown

This is a full installation of WordPress with the following changes :

All the "twentyxxxxxxx" themes are removed
Default plugins "akismet" and "hello dolly" are removed
The wp-content folder is renamed to assets
Language support is enabled and set to en_CA by default. Lang files are stored in lang
uploads folder is renamed to media.

Several methods were used to make it easier to secure your wordpress installation as follows :

Updated `wp-config-sample.php`

You should copy wp-config-sample.php to wp-config.php making any adjustments for your site. (database credentials, etc), prior to running the WordPress installation script as you normally would.

htaccess is pre-configured

While the .htaccess file is pre-configiured, you will still need to make some minor adjustments such as:

Change example.com and example\.com to your domain.
Update 123\.123\.123\.123 to the IP address you wish to allow access to the wp-admin/ folder

After installation

Edit the lockitdown.sh script, and change the last line so the path is the same as your uploads path (if you changed it from assets/media).

You will then want to run the lockitdown.sh script from your wordpress root (included), and delete it after. This will set the access modifiers on all files to 404 (read, none, read), and on all folders to 515 (read+exec, exec, read+exec). It will also ensure the directory assigned for uploading is writable. After this, it will delete the WordPress install script, license.txt, and readme.html files. You should delete the lockitdown.sh script after running it.

Notes

There is now a .htaccess file inside assets/media which disables all exec file handlers (scripts will not run from this folder), so even if an attacker uploads a file here, it will not execute.

There is a plugin we wrote called "lock-it-down" and is the ONLY plugin in this installation. Enabling this plugin will do the following:

Prevent WordPress from overwriting your .htaccess file
Disable the author archives page.
Disable user registration.
Turns off the multiple sizes for image uploads. Only the original will be used.
Disable theme and plugin automatic updates.

After completing your installation, you should ensure that the credentials used for the database settings, are limited to only what you need.
