Hello Wordpress and Nginx Experts, I am quite happy with my own set up of Wordpress site. It is quite fast. However, I still want to harden its web security with more Nginx tweak. I do not want those commercial Wordpress plugins which may add something to the present Wordpress database which is running very well. It you know some Nginx conf which can do these web security hardening, please share or refer me to the URL. Thanks for your attention.
