scp

Description: Secure Copy (remote file copy program).

Security Relevance: scp, or Secure Copy, provides a (relatively) secure means of copying files from one host to another. It works much like rcp but uses ssh to facilitate the transfer. (ssh or Secure Shell is a secure login program that provides encrypted sessions.) For more information, please see Chapter 10, "Protecting Data in Transit," and sshd in this appendix. Also see ssh, sshd, ssh-agent,and ssh-keygen, both in this appendix and in their respective manual pages.
