MANCHESTER, N.H.--(BUSINESS WIRE)--More than 144 billion emails are sent every day and a large portion of that are vital transactional emails sent from businesses across the world. As a result the incentive for spamming and phishing attacks is on the rise. The only true way to know whether the emails in your inbox are coming from a verified sender is to use DNS.
“The cost of having your passwords compromised is becoming so high that you can never be too safe. Using DMARC is just another security layer we advise.”
Traditionally, DNS is associated with keeping websites performing fast and preventing downtime. However, Domain-based Message Authentication, Reporting & Conformance (DMARC) is a new way of authenticating email delivery by using DNS. DMARC standardizes how email receivers perform authentication by using Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). These two technologies both store their records in DNS.
This works by allowing a sender to indicate that valid emails from their company are protected by SPF and/or DKIM. If the email that arrives does not pass either of those authentication methods, then the receiver knows to junk or reject the email, thereby avoiding harmful messages. This method eliminates the guesswork, which is why Dyn, the worldwide leader in Internet Infrastructure as a Service, recommends it to their email clients.
“We use DMARC on Dyn’s corporate mail and are advising customers on how to use it as well,” said Mike Veilleux, Dyn Director of Email Product. “The cost of having your passwords compromised is becoming so high that you can never be too safe. Using DMARC is just another security layer we advise.”
While this innovative use for using DNS to verify emails dates back to only 2011, Dyn has seen the connection between DNS and Email Delivery for years. In fact, DNS plays a major role in the Internet Infrastructure as a Service industry.
While everyone loves it when a website deploys new technologies, features or operational practice, this increases the reliance on DNS. As a result, it quickly becomes a question whether a company will be able to get the same value from their own internal DNS servers or get more value from a widely dispersed – ideally Anycast – and mature feature set like the one Dyn offers.
“People underestimate the importance of the DNS in everything they do online,” said Andrew Sullivan, Dyn Director of DNS Engineering. “The increased dependency on technology means an increased dependency on the DNS.”
