Tunneling is the process of enclosing private data in an ordinary, encrypted TCP/IP SSH packet, and channeling the information from the SSH session on the network connection. SSH has the ability to “tunnel” information and applications. To properly decrypt information, a computer must know which “key” to use as reference. The process of translating the information back into its original form is called decryption. A malicious user gaining root access to the recipient machineĮncryption is a process of translating information that is legible to humans into information that can only be read by a computer.A malicious user gaining root access to host (remote) machine.Authentication means determining someone’s identity. Typically SSH Protocol follows three steps for establishing a secured connection between two end points > Authentication, Encryption and Integrity. Essentially protects against any network attack SSH is a protocol, a kind of specific program which allows for secured communication across a network.Attacks based on listening to X authentication data and spoofed connection to the X11 server SSH (Secure Shell) is a secure replacement for older TCP protocols such as rexec, rsh, rlogin, telnet, and ftp.
Manipulation of data by people in control of intermediate hosts.Interception of clear text passwords and other data by intermediate hosts.DNS spoofing – an attacker forges name server records.IP source routing – a host can pretend that an IP packet comes from another trusted host.IP spoofing – a remote host sends out packets which pretend to come from another trusted host.
#SSH SHELL SECURE PASSWORD#
By using SSH’s slogin (instead of rlogin), the user initiates an entire login session, including password transmission, that is encrypted.
It is a replacement for rlogin, rsh, rcp, rdist and telnet. It provides strong authentication and secure encrypted communications between two hosts over an insecure network. Developed by SSH Communications Security Ltd., SSH is a program for logging into a network computer remotely, executing commands on a remote machine, and moving files from one machine to another.
