What is SSH (Secure Shell Access)?


SSH (Secure Shell) is a program to log into another system over a network, to
execute commands in a remote machine, and to move files from one machine to
another. It provides strong authentication and secure communications over unsecure
channels. It is intended as a replacement for rlogin, rsh, telnet and rcp.

Additionally, SSH provides secure X connections and secure forwarding of arbitrary
TCP connections.

How does it work?
All communications are encrypted using IDEA or one of several other ciphers (three-
key triple-DES, DES, RC4-128, TSS, Blowfish). Encryption keys are exchanged using
RSA, and data used in the key exchange is destroyed every hour (keys are not saved
anywhere). Every host has an RSA key which is used to authenticate the host when
RSA host authentication is used. Encryption is used to protect against IP-spoofing.
Public key authentication is used to protect against DNS and routing spoofing.
