Folx frequently ask me about security culture, both technical and social, so here's a reading list (in maybe the order you should read them). There's some overlap and contradictions between the zines, but that's not a bad thing. No one is completely right (not even me), and with something as likely to have serious consequences as security errors, always get at least 2 opinions.
First up is "Confidence, Connection, Courage, Trust." It's the best zine out there for finding a starting point for developing a security culture. It discusses how to create security culture without becoming paralyzed by paranoid.

Our phones are omni present, and there are probably more misconceptions about mobile phones than anything else related to security. "Mobile Phone Security" explains how phones work and how they can endanger us, and it gives concrete recommendations for a wide variety of scenarios. It's available in english, italian, spanish, and german.
