WordPress leaks usernames in several ways. In truth there is no way to fully prevent user enumeration, particularly if your website makes use of authors pages. However, you can certainly reduce the attack surface and make user enumeration harder by following the below steps:

• Disable the WordPress REST API if you are not using it,
• Disable WordPress XML-RPC if you are not using it,
• Configure your web server to block requests to /?author=<number>,
• Don’t expose /wp-admin and /wp-login.php directly to the public Internet.

as you know that WordPress is one of the most famous CMS in the world but unforunatily it is not secure enough and we have to protect it somehow abd also we need to setup some cache configuration in the htaccess

First thing you need to do is to disable directory listing by adding this line to .htaccess

Options All -Indexes

the other thing you need to do is to setup the objects cache (image/css files/ js files)

this is one of the best code we can use 

When you install WordPress it is very important to install some plugins that can protect your website, here we will list some of them

Update Drupal core via Drush

- Activate maintenance mode

drush state-set system.maintenance_mode 1

- Clear the cache

drush cache-rebuild

- Update the Files : please choose one of the below options

    - Update Drupal 8 core
           drush pm-update drupal

    - Update a single module
          drush pm-update module_name

add this code to .htaccess

#1
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# 2 Redirect to HTTPS
RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
