Test 3 Flashcards
The MIME specification extends the email message format beyond plain text, enabling the transfer of graphics, audio, and video files over the Internet mail system. S/MIME is an enhanced version of the MIME protocol that enables email security features by providing encryption, authentication, message integrity, and other related services.
True
What is the name of a network protocol that enables secure file transfer over SSH?
SFTP
SFTP is an extension of the FTP protocol that adds support for SSL/TLS encryption.
