You may want to consider using Anonymous FTP to provide a convenient way for users to access non-confidential material easily. Anonymous FTP enables unprotected access (no password required) to selected information on a remote system. The remote site determines what information is made available for general access. Such information is considered to be publicly accessible and can be read by anyone. Before configure Anonymous FTP, you should weigh the security risks and consider securing your FTP server with exit programs.
A hacker can mount a "denial of service" attack with your FTP server to disable user profiles on the system. This is done by repeatedly attempting to log on with an incorrect password for a user profile until the user profile is disabled. This type of attack disables the profile if it reaches the maximum sign on count of five.
