Why each option
For ensuring in-transit confidentiality of an emailed security assessment report, S/MIME is the appropriate protocol. S/MIME provides cryptographic security services for electronic messaging, including encryption to protect confidentiality during email transmission.
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and signing of MIME data, commonly used for email. It provides both confidentiality (through encryption) and integrity/authenticity (through digital signatures) for email messages, ensuring the security assessment report remains confidential in transit.
FTPS (FTP Secure) is used for secure file transfer, not for securing email communication.
DNSSEC (Domain Name System Security Extensions) adds security to the DNS protocol by digitally signing DNS records to prevent spoofing, but it does not protect email confidentiality.
AS2 (Applicability Statement 2) is a specification for securely exchanging EDI (Electronic Data Interchange) data over the Internet, typically for business-to-business transactions, not for general email confidentiality.
