More than half of the email domains managed by the White House’s Executive Office of the President (EOP) have not yet implemented an email security tool designed to protect users from phishing attacks, according to new research.
The Department of Homeland Security (DHS) has required that federal agencies and departments operating .gov domains implement the tool, known as the Domain-based Message Authentication, Reporting, and Conformance (DMARC).
DMARC enables organizations to flag potentially fraudulent emails that fail authentication tests or, when stronger settings are turned on, send the messages directly to a recipient’s spam folder or block them entirely.
