This is my first question here on Security, so please forgive me if I'm in the wrong place for asking this.
I am a computer science teacher currently teaching classes of teenage students age between 14 and 16. I want to give my class some lectures about "Computer Security"; I write it with quotes because they are not computer scientist at all, I just taught them a bit of programming, so what I need might not be exactly classified as "Computer Security".
What I am actually looking for is a good starting point (resources, books, blog posts, ecc.) to give them a glance about security from an end-user point of view like, for example, using smart passwords, good practices when surfing the Web, all those things that we, as computer guys, (should) use.
Can anybody help me on this quest? Thanks in advance.
