Améliorez la sécurité de WordPress dans les ressources non publiques

Je suis nouveau sur wordpress et je souhaite améliorer la sécurité de multisite wordpress en masquant des ressources non publiques, par exemple. wp-admin, wp-config etc.

Mon paramètre semble fonctionner, mais je ne sais pas si ce paramètre peut casser quelque chose (fonctionnalités de base, plug-in populaire, etc.)

  1. Mes réglages sont-ils bons de manière générale?
  2. Mes paramètres améliorent la sécurité réelle ou je perds mon temps?

httpd-vhosts.conf (Apache)

# Disallow public access php for .htaccess and .htpasswd files
<Files ".ht*">
    Require all denied
</Files>

# Disallow public access for *.php files in upload directory
<Directory "/htdocs/wp-content/uploads/">
   <Files "*.php">
       deny from all
   </Files>
</Directory>

# Disallow public access for... 
<Files "wp-config.php">
   order allow,deny
   deny from all
</Files>

<Files "readme.html">
   order allow,deny
   deny from all
</Files>

<Files "license.html">
   order allow,deny

</Files>

<Files "license.txt">
   order allow,deny

</Files>

# Because we do not use any remote connections to publish on WP
<Files "xmlrpc.php">

Utiliser remove_action() peut être supprimer les liens inutiles, par exemple:

remove_action('wp_head', 'rsd_link'); //removes EditURI/RSD (Really Simple Discovery) link.
remove_action('wp_head', 'wlwmanifest_link'); //removes wlwmanifest (Windows Live Writer) link.
remove_action('wp_head', 'wp_generator'); //removes meta name generator.
remove_action('wp_head', 'wp_shortlink_wp_head'); //removes shortlink.
remove_action( 'wp_head', 'feed_links', 2 ); //removes feed links.
remove_action('wp_head', 'feed_links_extra', 3 );  //removes comments feed.
