This directive prevents the server from generating a directory index when no default file is present. Instead, the server returns a 403 Forbidden error, denying access to the folder listing. A blank index.html or index.php file can also be placed in a directory to prevent directory listing.
When you access a directory on a web server that does not contain a default index file (like index.html or index.php ), the server may display a parent directory index. This index is a raw, automatically generated listing of all the files and subdirectories within that folder. It typically appears as a simple table with columns for name, last modified date, size, and a description, complete with a “Parent Directory” link that allows you to navigate up one level in the folder hierarchy.
"Simplex provides a very capable file indexing and search service allowing you to find a file among huge no. of files located under open directories of web servers. It only provides access to already available files in the same way Google does but in a formalized easy query search."

The list of files, sub-folders, or assets stored within that specific directory.

This search tells Google to look for pages with index.of in the title, containing the word "lifestyle," while excluding common webpage extensions. The results often lead directly to directory indexes rather than standard webpages.

Ensure the configuration file explicitly sets autoindex off; within the server block.
Even when a directory listing itself does not directly expose sensitive information, it can still leak information that helps an attacker plan further actions against the server. For example, knowing the folder structure, file naming conventions, or the type of software used by the server can be valuable reconnaissance data for a malicious actor.
