The DMARC framework was introduced to secure your outbound emails and from receiving fraudulent impersonated emails by authorizing your legitimate sending sources. This protects your organization from BEC fraud and from receiving malicious spoofed emails.
The implementation of this framework is the responsibility of the domain owner — For example, we, as DMARC360, have to make sure that we have performed the required analysis and authorized our legitimate email sending sources to guarantee that no one receives an email impersonating our domain dmarc360.com
DMARC allows the email sender and receiver to collaborate in order to implement the framework. The email sender is able to define rules for the receiver on what actions to take on their potentially spoofed emails, and in turn, the receiver can send back reports containing details of where the sender’s emails originated from, along with the result of SPF & DKIM when validating the authenticity of those emails.
This process gives visibility and control to the email admins of their outbound emails, protecting their brand identity and reputation.
The DMARC framework is built upon two existing mechanisms; SPF & DKIM. These mechanisms enable you to authorize your legitimate email sending sources. In short, SPF allows you to authorize which IP addresses can send emails from your domain, and DKIM is a digital signature on your emails, adding a layer of integrity. Both of these protocols provide a form of authentication, and enabling the DMARC framework will help you enhance them further.
In addition, the DMARC alignment process is also a vital aspect of the framework to eliminate your domain’s impersonation. To understand how this works, please click here.
Enabling the DMARC check for incoming emails and configuring your DMARC record to secure your outbound emails can significantly protect you and everyone else from receiving fraudulent impersonated emails.
