Less than two weeks after a report showed that only one of 26 web domains managed by the Executive Office of the President fully implemented a required email security protocol that prevented fraud, five more domains have implemented that protocol, according to the Global Cyber Alliance, a cybersecurity advocacy group.

Why it matters: That protocol, known as DMARC, prevents fraudulent emails that appear to be from White House accounts from showing up in would-be victims's inboxes. Fake White House emails could be used in scams or to stir up diplomatic or political trouble.

The details: Last year, the Department of Homeland Security issued a directive requiring federal agencies to implement the protocol.
