Wordpress wp-config file better security - wordpress

Question

I have few questions regarding the wp-config.php file in Wordpress. I moved the file from the wordpress installation directory, above the www directory and inside one of the home folders. I followed this tutorial. In the main wordpress directory i added another wp-config.php file with the following include path:
<?php
include('/home/www/web55438/files/wp-config.php');
?>
Inside the files folder i also added the following .htaccess file.
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
#Prevend directory browsing
Options All -Indexes
#Protect files from displaying
<Files wp-config.php>
order allow,deny
deny from all
</Files>
#Protect htaccess file
<Files ~ "^.*\.([Hh][Tt][Aa])">
order allow,deny
deny from all
satisfy all
</Files>
My questions are: Is this a secure way for handling the wp-config.php file with an absolute path? Is the .htaccess file configured properly? And what would you change for better wordpress security?
Thanks

Answer 1

<Files wp-config.php>
order allow,deny
deny from all
</Files>
change it to
<Files wp-config.php>
order deny,allow
deny from all
</Files>
This way, you are denying access to wp-config.php

Answer 2

As you are moving your config file from default location to location above your root of website. Then this is proper way to include that file
