Microsoft has released a free — and lengthy! — e-book covering a wide range of security topics. Although intended for teenagers, the book offers a solid enough look at using the internet safely, and it's suitable for anyone who needs a primer on internet security.
It's difficult to write books for teenagers that don't fall into the "trying too hard to be cool" trap, but Microsoft has done an admirable job. The text is a comprehensive guide for teenagers (and new computer users) that covers everything from how to spot phishing tactics to setting up your browser to protect against browser-based exploits to dealing with cyberstalking and bullying. It also provides interesting history and real-world examples of the harm that can come from security vulnerabilities.
The 253-page book is a free download and Creative Commons licensed. You can download the entire book at the link below, or just the chapters you want to share with family members, students or members of your organisation.
