While this requires manual maintenance, it acts as an excellent defense-in-depth fallback mechanism. Many content management systems, like WordPress, place empty index files in their uploads directories by default for this exact reason.

You might think your files are safe because "nobody knows the URL." In reality, attackers don't need to guess. They use automated techniques to find exposed directory indexes. 1. Google Dorking

1. What is an "Index of /" and How Do Private Images Get Exposed? Many content management systems, like WordPress, place empty

Many software installers create temporary configuration files, setup scripts, and database migration templates. Once your installation is complete, immediately delete the /install or /setup directory from your server. Leaving it active allows attackers to re-run scripts or exploit installation variables.
