How to restrict access to some files on server?

This .htaccess code should return 403 error on several sensivel files that usually stay forgotten on the server.

# SECURE LOOSE FILES 
<IfModule mod_alias.c>
	RedirectMatch 403 (?i)(^#.*#|~)$
	RedirectMatch 403 (?i)/readme\.(html|txt)
	RedirectMatch 403 (?i)\.(ds_store|well-known)
	RedirectMatch 403 (?i)/wp-config-sample\.php
	RedirectMatch 403 (?i)\.(7z|bak|bz2|com|conf|dist|fla|git|inc|ini|log|old|psd|rar|tar|tgz|save|sh|sql|svn|swo|swp)$
</IfModule>
