Secure NGINX configuration for WordPress

WordPress Security for NginX

WordPress is the most popular CMS for running a website. As such, it is the target for all kinds of malicious bots. The most effective way of reducing security risks associated with WordPress is the proper server configuration. Secure WordPress NGINX configuration must be built on the assumption that any unknown script is malicious.

# This file includes common security considerations for wordpress using nginx.
#
# The goal is to block actions which are usually dangerous to wordpress.
# Additionally, we block direct access to PHP files and folders which should not

# Also have included exceptions for plugins that are known to require this access.
