DMARC Diligence (Part 2) : The Forgotten Domains : A Hidden Vulnerability

In this second article of the “DMARC Diligence” series, we shift our focus towards securing non-sending or “forgotten” domains and outline a strategy for their protection through DMARC implementation. 

Recap Of Part 1 

You may remember that in part one of this DMARC Due Diligence series of articles we laid the groundwork by exploring the essentials of the email authentication protocols SPF, DKIM, and DMARC. We learned how these mechanisms work in tandem to validate email sources, ensuring that only authenticated emails reach their intended destinations. The primary takeaway was the importance of implementing these protocols to shield email communications from the prevalent threats of phishing and spoofing attacks.
