SSH VS Telnet

“No more long distance communication” as the slogan implies, the efficient exchanges of messages through the modern network protocol advancements was made possible due to the SSH and Telnet. With the aid of high technology and information management, the speed and security were enhanced for effective delivery of connections. The SSH also known as Secure Shell is featured with the security measures that protect the computer users against the threat whereas the telnet does not have the security features.

  SSH Telnet
Stands Secure Shell Telecommunications and Networks
Designed for Public Networks Private networks
Security More secured Less secured
Authentication Utilizes public key No authentication
Data transmission Data is encrypted Plain text
Ideally used for Ubuntu, Solaris, Red hat-Linux, CentOS, Unix UNIX

An SSH is designed to work across the public network and authenticates the sources of the information. On the other hand, the telnet is engineered to perform transmission across private networks only and it lacks the authentication features which might be an intercept to someone to access the data. Moreover, the SSH encrypts the information and every data contains security measures while Telnet transmits information within plain text only. In terms of the usage of the bandwidth, the SSH has a bit more overhead rather than the telnet. Most of the users are comfortable in relying on the SSH network protocol than the telnet because of its superb security and speed features. Which do you prefer an SSH or an HPLC?
