Secure Remote Logins and File Copying


Most Linux security books strongly recommend using SSH and SCP over TELNET and FTP because of their encryption capabilities. Despite this, there is still a place for FTP in the world thanks to its convenience in providing simple global access to files and TELNET, which is much easier to implement in price-sensitive network appliances than SSH. Consider all options when choosing your file transfer and remote login programs and select improved security whenever possible as the long-term benefits eventually outweigh the additional cost over time.
