The nerve roots pass through these joints to go from the spinal cord to the arms, legs and other parts of the body. These joints also allow the spine to bend and twist, and they keep the back from slipping too far forward or twisting without limits.

Secure FTP is a broad term that refers to two different technologies that can encrypt both authentication information and data files in transit. 1  FTPS refers to secure FTP that uses SSL or TLS for encryption. 2  SFTP refers to the use of Secure Shell or SSH network protocol to exchange data over a secure channel. FTPS is very similar to FTP and uses extensions to FTP that add support for the Transport Layer Security (TLS RFC 4217) and Secure Socket Layer (SSL RFC 2228) protocols. 2  Like FTP, FTPS uses two connections â a command channel and a data channel.
