Back in May, I released a leaflet on Mobile Phone Security advice for ordinary people to be able to manager their own security for their devices. I promised that we’d be releasing the longer whitepaper that accompanies it soon, so here it is. We’ve released it as a short book, which can you can initially purchase from this site. The book covers some of the history of mobile security, things that have happened in industry and security design decisions that have been taken to try and protect users over the years. It also talks about various issues and incidents, their impact and what users should do to try and mitigate those things. There are also sections on personal safety and lost and stolen phones. I really hope this is useful for people!
