We already protect all native wordpress sites on server by default !

However, if you need to use xmlrpc.php :

1. Change your nginx profile, go in your cpanel, in section 'Nginx', click on 'Nginx-Manager'


Choose first your domain and click 'Configure'
You are now in 'Application server', leave 'PROXY' and click 'Submit'
Leave httpd, and see dropdown list below text : "Select Application template"
Choose in this case template 'YOORshop xmlrpc', and click 'Submit'


2. Manage allowed IPs, if not using jetpack : Add this to your .htaccess, to restrict access to some IPs and protect this file from attacks, here is example with IP of our VPN :

<Files "xmlrpc.php">
order deny,allow
deny from all
allow from 87.98.172.169
</Files>

You can test and access your website from an IP not allowed on URL /xmlrpc.php, you must see a 403 Forbidden

 

3. Manage allowed IPs with Jetpack, (don't use point 2 at same time), you will have to install this plugin which will manage automatically their IPs to allow :
