The Department of Homeland Security announced a new binding directive today for federal agencies to adopt basic web and email security features. They've been told to use DMARC, an email security protocol to protect against spammers and phishers, and STARTLLS, which would send email over an encrypted channel when available.

Why it matters: Jeanette Manfra, Assistant Secretary for the Office of Cybersecurity and Communications, warned in a statement: "A single spoofed email can compromise the security of an entire organization, and a breach at one organization can sometimes leave an entire industry open to similar attacks and vulnerable to fraud."
