SMTP Strict Transport Security Comming soon for Gmail and Other Webmail Users

Google, Microsoft, Yahoo and Comcast are expected to adopt the standard Mail services and implement the SMTP Strict Transport Security following by  Gmail users soon.

Elie Bursztein, the head of Google’s anti-abuse research team, said at RSA Conference that SMTP STS will be a major impediment to man-in-the-middle attacks that rely on rogue certificates that are likely forged, stolen or otherwise untrusted.

All the webmail sevice providers bringing a measure of security similar to certificate pinning to the webmail services.

According to the Draft of which was submitted to the IETF in March 2016.

SMTP STS is a mechanism enabling mail service providers to declare their ability to receive TLS-secured connections, to declare particular methods for certificate validation, and to request sending  SMTP servers to report upon and/or refuse to deliver messages that cannot be delivered securely.

Bursztein’s declaration came during a discussion which he represented how diverse dangers to corporate and individual Gmail records, for example, spam, phishing, malware, pantomime and capture assaults change by industry and geology.

Bursztein’s said “Every minute, we have to stop more than 10 million attacks with 99.9 percent precision. The way we are doing this is reacting quickly to emerging threats.”

  The mechanism described is in draft separated into four logical components:

  • Policy semantics: whether senders can expect a server for the recipient domain tosupport TLS encryption and how to validate the TLS certificate presented
  • Policy authentication: how to determine the authenticity of  published policy delivered via DNS
  • Failure report format: a mechanism for informing recipient domains about aggregate failure statistics
  • Failure handling: what sending MTAs should do in the case of policy failures

Related Technologies of DANE Record designed to upgrade opportunistic encryption into required encryption.DANE requires DNSSEC [RFC4033] for the secure deliver of policies; the mechanism described here presents a variant for  systems not yet supporting DNSSEC, and specifies a method for reporting TLS negotiation failures.

According to the (IETF) The primary difference between the mechanism described here and DANE is that DANE requires the use of DNSSEC to authenticate DANE TLSA records, whereas SMTP STS relies on the certificate authority (CA) system and a trust-on-first-use (TOFU) approach to avoid  interception.

Burszstein said that , a decision to add visual cues to users that certain Gmail messages may be untrusted helped spike adoption of encryption. One such measure was a UI change to display a broken lock in the inbox indicating that the email about to be sent is being sent in the clear.

“This tells you the email you are about to send is not encrypted and could be intercepted in transit,” he said. “This helps the user make a better choice by highlighting this to the user.”

He also pointed to visual cues on the authentication front such as Gmail’s assigning of icons to trusted users while throwing up a red question mark for unauthenticated senders. This too was a driver in increasing adoption of all three protections, reducing the number of unauthenticated messages in 2014 (5.8 percent) to last year (1.8 percent).
