It's not exactly the intention everyone has when they sign up, as the whole point of Facebook is to share your life with your friends. It hooks us into a global community and the experience does depend on us making certain privacy sacrifices.
So how do you balance being social with staying safe?
On Facebook alone, the average person shares 13 pieces of personal information ranging from a fairly innocent name/email combo, all the way to mothers maiden name and home address.
It doesn't sound like a lot, but those 13 pieces have the power to unravel your life within minutes.
Even checking in at home or a favorite location has become the norm, helping to create a multi-dimensional online identity. The details are available to anyone who cares to look, whether they're a friend keeping in the loop, or someone with a much darker agenda.
The problem is, you just don't know who's looking at your profile or why.
For example, someone could try accessing your email account by clicking the 'Forgot password' link. The email service follows its security rules and asks identifying questions like 'which high school did you go to? What is your pet's name?' Unfortunately, the most common identifying checks and answers are probably available on Facebook.
Once your email address is compromised, hackers can use that to break into other services and go through, clicking 'Reset Password' on site after site, account after account – they have full access to your email, so there's nothing stopping them from emptying your bank accounts – or worse.
