Secure Shell (SSH-2) supports authentication, compression, confidentiality, and integrity, SSH is commonly used as a secure alternative to all of the following protocols below except:
Suggested Answer:D🗳️
HTTPS is used for secure web transactions and is not commonly replaced by SSH. Users often want to log on to a remote computer. Unfortunately, most early implementations to meet that need were designed for a trusted network. Protocols/ programs, such as TELNET, RSH, and rlogin, transmit unencrypted over the network, which allows traffic to be easily intercepted. Secure shell (SSH) was designed as an alternative to the above insecure protocols and allows users to securely access resources on remote computers over an encrypted tunnel. SSHs services include remote log-on, file transfer, and command execution. It also supports port forwarding, which redirects other protocols through an encrypted SSH tunnel. Many users protect less secure traffic of protocols, such as X Windows and VNC (virtual network computing), by forwarding them through a SSH tunnel. The SSH tunnel protects the integrity of communication, preventing session hijacking and other man-in-the-middle attacks. Another advantage of SSH over its predecessors is that it supports strong authentication. There are several alternatives for SSH clients to authenticate to a SSH server, including passwords and digital certificates. Keep in mind that authenticating with a password is still a significant improvement over the other protocols because the password is transmitted encrypted.
The following were wrong answers: telnet is an incorrect choice. SSH is commonly used as an more secure alternative to telnet. In fact Telnet should not longer be used today. rlogin is and incorrect choice. SSH is commonly used as a more secure alternative to rlogin. RSH is an incorrect choice. SSH is commonly used as a more secure alternative to RSH.
