Securing browsable directories?

ℹ️ Support

Many Nextcloud directories seem to be browsable without authentication.
The entire /apps directory is accessible externally without providing credentials.
Is this expected - is there a standard way to block access to these folders?

NextCloud V13.0.6
PHP 5.6.39
