QuestionQ714

Network and Communications Security

Secure Shell (SSH-2) provides authentication, compression, confidentiality, and integrity. SSH is commonly used as a secure alternative to all of the following protocols except:

  • A telnet
  • B rlogin
  • C RSH
  • D HTTPS
Explanation

SSH commonly replaces insecure remote-access protocols such as Telnet, rlogin, and rsh. HTTPS already provides encrypted web communication through TLS, so it is not a protocol that SSH generally replaces.
