Hi,
In Apache , we used to use deny from all directive to deny access to xmlrpc.php , but this directive doesn’t work in OLS, so there is an alternative way to do
In your .htaccess file , add following code
RewriteRule xmlrpc - [F,L]
And then restart OLS, then when you access /xmlrpc.php , you will have a 403 forbidden result 
Best regards,
