Today spoke about hardening WordPress at the WordPress meetup . It's a nice experience as the audience were from mixed backgrounds (developing, marketing, product management, etc). My slides and links are available in the Pinboard . I have also shared an actionable checklist to harden a WordPress instance, that anyone can use in the form of the Restyaboard app (Restyaboard similar to Trello but open source and can self-host).
