https://searchsecurity.techtarget.com/answer/What-are-the-most-important-email-security-protocolsOut of the given options, the protocol that would provide in-transit confidentiality protection for emailing the final security assessment report is S/MIME (Secure/Multipurpose Internet Mail Extensions).
S/MIME is a protocol that provides end-to-end encryption for email messages, including the attachments. It ensures that the email message remains encrypted during transmission and can only be read by the intended recipient who possesses the private key to decrypt the message.
FTPS (File Transfer Protocol Secure) is a protocol that provides secure file transfer over an SSL/TLS connection. It is used to transfer files between servers and clients securely, but it does not provide email encryption.
DNSSEC (Domain Name System Security Extensions) is a protocol used to provide data integrity and authenticity to the DNS (Domain Name System) data. It does not provide email encryption.
AS2 (Applicability Statement 2) is a protocol used to transfer EDI (Electronic Data Interchange) documents securely over the internet. It does not provide email encryption.
Therefore, option A, S/MIME, is the correct answer to ensure in-transit confidentiality protection while emailing the final security assessment report.
