Or more precisely:

Three essential controls eliminate the risk: First, disable directory listing entirely in web server configurations (e.g., Options -Indexes in Apache). Second, enforce authentication for any sensitive parent directory, using HTTP basic auth, OAuth, or IP whitelisting. Third, deploy a robots.txt file and use noindex headers, though these are only advisory. Regular automated scans for open directories, using tools like dirb or custom scripts, can detect misconfigurations before external parties do. Finally, for truly exclusive data, place it outside the web root entirely, accessible only by server-side scripts. index of parent directory exclusive

Use proper authentication, authorization, and filesystem permissions for real security. Rare whitepapers or out-of-print niche publications
