The CDDIS, located at NASA GSFC, has therefore addressed these concerns and provided alternative methods for access to its archive for continued easy and automated download of its contents. Government agencies have become increasingly concerned about this legacy protocol and ensuring data integrity for the user community and have disallowed the use of the ftp protocol. Although this protocol allows users to easily automate file downloads, many organizations, data systems, and users have already migrated from ftp or are actively pursuing a move away from the protocol due to problems from a system and security standpoint. Since its inception, users have relied on anonymous ftp for accessing and downloading files from the system.
