Magento admin notice "Your web server is configured ......... hosting provider."

Here is solution to the issue, which comes in magento admin dashboard.

"Your web server is configured incorrectly. As a result, configuration files with sensitive information are accessible from the outside. Please contact your hosting provider."

Issue Explanation :-

The issue relates with easy access to configuration file by web, i.e.,  

http://sitename/app/etc/local.xml

And this should be made unreadable by web.

Solution :- 

Depending on server apache settings any of the following solution may work.

1. Try changing permissions of  app/etc/local.xml to 660. Then check if http://sitename/app/etc/local.xml shows forbidden(or access denied or any error) & then test magento admin dashboard if that error is gone.

2. In case 1 fails, then 

 Try changing permissions of  app/etc/local.xml to 600. Then check if http://sitename/app/etc/local.xml shows forbidden & then test magento admin dashboard if that error is gone. 

3. In case, 1 & 2 both fails then lets discuss it further with me, as there might any other security loophole that too has to be fixed.
