Preventing Unauthorized Email Spoofing with DMARC
Talk by John Wilson
SMTP lacks authentication. This basic oversight has proven a boon for cybercriminals, who leverage email’s insecurity to steal billions of dollars every year. In this session you’ll learn about DMARC, a standard for email authentication that can prevent unauthorized email spoofing.
After a technical overview of SPF, DKIM, and DMARC we will discuss the open source tools available to help you implement these standards. We’ll explore some implementation issues, propose some work-arounds, and end with some adoption statistics.
