Security Headers for WordPress .htaccess File
How to manually add the recommended security headers to your website.
Disable Directory Listing with the .htaccess File
If you create a new directory and don’t put an index file in it, anyone can see all contents of that directory by going straight to the URL. Add this to the .htaccess file
Disallow File Editing in WordPress
Add this to the wp-config.php file at the very end. This will disallow file editing so no one will be able to modify any of the files through the WordPress backend.
Remove the WordPress Version Number
Removes the version number from WordPress for security reasons.
