Description: The Applicability Statement for Secure Health Transport is intended to provide constrained conformance guidance on the interoperable use of a set of RFCs describing methods for achieving security, privacy, data integrity, authentication of sender and receiver, and confirmation of delivery consistent with the data transport needs for health information exchange.

The document describes how to use SMTP, S/MIME, and X.509 certificates to securely transport health information over the Internet. Participants in exchange are identified using standard e-mail addresses associated with X.509 certificates.The data is packaged using standard MIME content types. Authentication and privacy are obtained by using Cryptographic Message Syntax (S/MIME), and confirmation delivery is accomplished using encrypted and signed Message Disposition Notification. Optionally, certificate discovery of endpoints is accomplished through the use of the DNS. Advice is given for specific processing for ensuring security and trust validation on behalf of the ultimate message originator or receiver.
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
