iThemes Security change .htaccess

Hello,

Does iThemes Security make the following change to the .htaccess file automatically:

<files wp-config.php>
order allow,deny
deny from all
</files>

This is as per this article:
https://premium.wpmudev.org/blog/keeping-wordpress-secure-the-ultimate-guide/

I am using iThemes Security but it doesn't seem to have done it.

Any thoughts would be greatly appreciated.

Thank you,
Mike
