DC 20510 (202) 224 5244 March 22, 2017 Lieutenant General Alan R. Director, Defense Information Systems Agency 6910 Cooper Ave. Fort Meade, MD 20755 Dear Lieutenant General Lynn: I write concerning the security of unclassi?ed military email and to urge the Defense Information Systems Agency (DISA) to enable an technology widely used across the federal government and the private sector, to better protect email communications. As you may know, the technology industry created ?fteen years ago to allow email servers to communicate securely and protect email messages from surveillance as they are transmitted over the internet. is widely supported by email server software but, critically, it is often not enabled by default, meaning email server administrators must turn it on. Major technology companies like Google, Yahoo, Microsoft, Facebook, Twitter, and Apple use as do the White House, Senate, and House of Representatives. Many agencies within the US. government also use like the National Security Agency, the Central Intelligence Agency, the Of?ce of the Director of National Intelligence, the Department of Homeland Security, and the Federal Bureau of Investigation. News reports indicate that mailmil servers did not appear to use as late as 2015, something my staff believes is still the case. My of?ce also has reason to believe the Army, Navy, Marines, and Coast Guard all rely on the mailmil service provided by DISA. The Air Force?s email server, us.af.mil, appears to have enabled While I understand the Department of Defense employs a number of other security technologies to protect classi?ed and unclassi?ed email messages, I am concerned that DISA is not taking advantage of a basic, widely used, easily-enabled cybersecurity technology. Indeed, until DISA enables unclassi?ed email messages sent between the military and other organizations will be needlessly exposed to surveillance and potentially compromise by third parties. I urge you to enable for mailmil and appreciate your prompt reply.
