@MikeRalphson as per on Slack message I'm happy to pick up Security above based on the content I'm producing for the OAI training course. Let me know if that helps at all - and if work is not already in progress somewhere - and if so please can we split into a separate ticket.

Thanks @SensibleWood , I'm pretty confident the work is not already in progress somewhere so we'd be more than happy for you to contribute! If you want to create an issue for what you're working on and assign it to yourself, that will also make it clearer for anyone else wanting to do the same thing.

We don't have detailed writing guidelines here, so take a look at what we have already and try to blend your knowledge in? Thanks for helping!
