File and Folder Access Check - Checking if the log folder is outside of public html
You can configure a log folder inside your Joomla! installation, this is where the Joomla! logging data is stored. A common security practice is to set up this folder outside of public HTML so that it cannot be accessible over the web.
RSFirewall!'s System Check feature verifies the folder's path and notifies you whether it is set up in a safe manner or not.
