Prevent Directory Listing
Directory Listing occurs when the web server does not find an index file (i.e. an index.php or index.html), if directory listing is turned on, the server will display an HTML page listing the contents of the directory.
Disclosure of this information could make a site vulnerable to attacks by revealing information that can be used by an attacker seeking to exploit a vulnerability in a WordPress plugin, theme, or even the web server itself.
While it is not a WordPress-specific security measure to disable directory listing, several WordPress sites running on default installations of Apache HTTP Server have directory listing enabled.
