With one subject!
Why people are not concerned about exposing their lives on the Internet? On a way that can put in danger not only themselves but their family and friends.
I'm writing below some info I collected just looking ramdomly for profiles on some social network websites.
Phones, credit card numbers, full address, if they have children, how many are they and their names, where they study, where they work, etc.
You can just find everything about everyone. They're really not concerned with someone they don't know looking their profile searching for something (possible with bad intentions).
We all read stories about people that met online "friends" and many of them ended very badly.
So, why does this happen?
It's because our society lives to deify celebrities and everybody is triyng desperately to get a space on the sun and they expect that somehow they'll get it using these tools?
Or it's just because they are not aware of the risks?
What can we (Security Professionals) do about it?
One sugestion I have is to ISC2 launch some web trainning for regular people teaching about online risks related to social network tools. It might be handy.
Another thing that must be done is to include basic security concepts as a basic school subject.
I would like to hear about initiatives related to prevent people about these risks on your countries
