A new study found that nearly all of the presidential candidates in the 2020 United States presidential election are behind on email security, despite the fact that email accounts are not the same. Hillary Clinton had been attacked and raped by Russian hackers just three years ago. Email security company Agari has confirmed that only Democratic candidate Elizabeth Warren uses a Message Reporting, Reporting and Compliance, or DMARC, authentication strategy to protect her email accounts. This email security feature sits on top of the Sender Policy Framework (SKF) and Domain Identification Mail (DKIM) security protocols that use cryptography to verify sender email and can mark it as spam . or reject it if the email is not validated correctly. . According to Agari, the remaining 11 candidates, including Bernie Sanders, Joe Biden and outgoing President Donald Trump, including Bernie Sanders, who has protected email security, do not use DMARC to protect their campaign areas.
