Secure Copy Protocol (SCP)
The Secure Copy Protocol (SCP) is another protocol based on Secure Shell (SSH) technology. SCP provides a secure means to copy files between systems on a network. By using SSH technology, it encrypts data as it travels across the network, thereby securing it from eavesdropping. It is intended as a more secure substitute for the Remote Copy Protocol (RCP). SCP is most commonly associated with UNIX or Linux platforms, though it is available as a command-line utility or as part of application software for most commonly used computing platforms. SCP operates at the application layer of the OSI model.
