The current economic climate is challenging, unscrupulous organizations around the world are more and more creative in pursuit of revenue, prompting a redoubling of effort from those of us striving to keep our customers safe.
Still, one of the most exploited mechanisms of the modern world is our email system, its contemporary function is vastly different from its original design intentions. Email systems have become more derivative then definitive, the increasing complexity placing it beyond the reach of all but the most specialized technology exponents.
Our goal is to bring clarity to confusing technology concepts, to help our customers make good decisions. Although we don’t pretend to be able to make everyone experts, describing complex systems simply is the hall mark of a good technology company. To wit, we present our best attempt for your edification…
Three contemporary technologies are used to secure modern email systems. Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain Message Authentication, Reporting and Conformance (DMARC).
SPF records are instructions embedded into the sending domain (i.e. domain.com). These instructions list those services permitted to send email on your behalf. (e.g., Microsoft or Google).
DKIM is a pair of private and public encryption keys used by a receiving server to confirm a message was sent from the domain it purports to originate from.
DMARC is a system that, offers your email administrator the opportunity to tell a receiving server what to do if a message fails either or both the SPF and DKIM checks. (i.e., nothing/quarantine/reject). It also provides a measure of reporting to your email administrator about messages sent on behalf of your domain by other services, legitimate or not.
In a modern world, all these things and more are needed to ensure email hygiene to keep us and our systems safe. More importantly, to protect the online reputation of our interactions with customers and suppliers, lest our legitimate messages are directed immediately to the junk folder or blocked by dynamic spam filter.
Implementing these technologies is a one-time cost, so if you would like to know more about how these can help keep your email systems safe and secure. Make contact with us, we are always more than happy to help.
