Which protocols use encryption to protect the confidentiality of data transmitted between two parties? (Choose two.)
A. FTP
B. SSH
C. Telnet
D. AAA
E. HTTPS
F. HTTP
Correct Answer: BE
Explanation/Reference:
An encrypted connection becomes useless if you’ve unknowingly connected to a bogus server or a malicious client. While SSH and SSL use symmetric cryptography to preserve the confidentiality of transmitted data, they use another form of encryption for authentication. Authentication allows one party to verify whether the other party is really who it claims it is. Reference: http://www.jscape.com/blog/ssl-vs-ssh-simplified
