Disable Anonymous FTP Access

Description

If any directories that contain dynamic scripts can be accessed via FTP by any group or user that does not require access, remove permissions to such directories that allow anonymous access. Also, ensure that any such access employs an encrypted connection.

Rationale

The directories containing the CGI scripts, such as PERL, must not be accessible to anonymous users via FTP. This applies to all directories that contain scripts that can dynamically produce web pages in an interactive manner (i.e., scripts based upon user-provided input). Such scripts contain information that could be used to compromise a web service, access system resources, or deface a web site.
