Secure Shell (SSH)


Developed by SSH Communications Security Ltd., Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authenticationand secure communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist.

SSH protects a network from attacks such as IP spoofing, IP source routing, and DNS spoofing. An attacker who has managed to take over a network can only force ssh to disconnect. He or she cannot play back the traffic or hijack the connection when encryptionis enabled.

When using ssh’s slogin (instead of rlogin) the entire login session, including transmission of password, is encrypted; therefore it is almost impossible for an outsider to collect passwords.

SSH is available for Windows, Unix, Macintosh, and OS/2, and it also works with RSAauthentication.

    An SSH service that provides secure and encrypted connections to traditionally non-encrypted services, such as e-mail or news. SSH port forwarding allows you to establish a secure SSH session and then tunnel TCP connections through it. It works by opening a connection to forward a local port to a remote port over SSH.

    SSID is short for service set identifier. SSID is a case sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN) that acts as a password when a mobile device tries to connect to the basic service set (BSS) — a component of the IEEE 802.11 […]
