Anonymous FTP allows a user to retrieve documents, files, programs, and other archived data from anywhere in the Internet without having to create a userid and password. With the special userid of “anonymous” the network user can bypass local security checks and have access to publicly accessible files on the remote system. You can allow anonymous FTP access to visitors wishing to download or upload files to your web site as if you were running your own FTP server.
Anonymous FTP grants all users the ability to access your upload directory, or any directory on your domain that has been set for “public” read/write permissions. Anonymous users can have access to upload or download files to and from your domain. So you must set the appropriate permissions for the directories on which you wish to restrict anonymous FTP access. You can restrict access to specific files and directories on UNIX servers using the File Manager by disabling public read and/or write access to the files or folders you don’t want people to see. This ensures that anonymous users will not be able to access the restricted files or directories.
