Some site owners don't want people, especially their competitors, know what features they have on their sites.
Because some sensitive information in language or configuration files can be accessed directly from browser, eg.
administrator/components/com_bank/language/en-GB/en-GB.com_bank.ini administrator/components/com_bank/config.xml components/com_bank/models/forms/transaction.xml
Although only technical people know about Joomla can figure out these links, access them and find out (or guess) what the features the site has, however the site owners want everything to be secret.
So is there any server side solution or any Joomla extension to forbid direct access to these INI and XML files?
