How can we secure communications between SMTP mail servers? Simply using TLS between servers will not prevent Man In The Middle(MITM) attacks. DNSSEC and DANE to the rescue! Using DANE, SMTP servers can validate X.509 certificates tied to TLS using DNSSEC lookups. In this lightning talk from Carsten Strotmann, learn how this all works and the current status of implementations. His talk, entitled “DANEs don’t lie – DANE/SMTP” is now available for viewing from the RIPE 68 site, and the slides are available for download.
