A security engineer, Joe, has been asked to create a secure connection between his mail server
and the mail server of a business partner. Which of the following protocol would be MOST
appropriate?
A.
HTTPS
B.
SSH
C.
FTP
D.
TLS
Explanation:
Transport Layer Security (TLS) is a cryptographic protocol designed to provide
communications security over a computer network. It uses X.509 certificates and hence
asymmetric cryptography to authenticate the counterparty with whom it is communicating, and to
exchange a symmetric key. The TLS protocol allows client-server applications to communicate
across a network in a way designed to prevent eavesdropping and tampering.
