If Trump hates leaks, he needs to give up his phone | John Naughton

The leader of the free world's 'invincible ignorance' about cybersecurity is worrying in the extreme

My favourite image of the week was a picture of the Queen opening the National Cyber Security Centre in London. Her Majesty is looking bemusedly at a large display while a member of staff explains how hackers could target the nation's electricity supply. The job of the centre's director, Ciaran Martin, is to protect the nation from such dangers. It's a heavy responsibility, but at least he doesn't have to worry that his head of state is a cybersecurity liability.

His counterpart in the United States does not have that luxury. To the astonishment of everyone in the tech community, King Donald is still tweeting and nattering away on his Samsung Galaxy phone, an Android device that in security terms is the equivalent of emmental cheese. When Trump was elected, most people assumed that he would give up his favourite phone, just as Obama had to give up using his beloved BlackBerry, in favour of something that had been "hardened" by the NSA. It hasn't happened.
