DNS Can Help Protect Your Emails Against Spamming And Phishing Attacks
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.
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 (News - Alert) 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
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
