In this age of hacking and cyber-warfare, the job of a diplomat can be quite a high-stakes one.

Take for example, Sir Kim Darroch, who resigned last month as the UK's ambassador to the US after a row over leaked emails.

He'd described Donald Trump as "inept" and his administration as "uniquely dysfunctional".

British police are investigating the leak but the events shook diplomats - with some saying it could've been any one of them.

So how can they be more cyber-savvy?
