Email Architecture and Message Security

The Ramifications of Email Architecture on Message Security

Steve Moitozo discusses the ramifications of email architecture on message security. The architecture of email communications was cast in the 1960s and the resulting designs of message routing protocols like SMTP determine the upper limits when it comes to the security of email as a communications channel.

This is not an exhaustive security analysis of all aspects of the email architecture as there are other operational factors that impact the overall security of email. Rather it is intended to help the viewer understand that there are limits to the level of security that can be achieved when using email.
