Let's face it. In today's world, we all have a 'digital footprint' - little bits of information about ourselves all over the Internet. Realistically, there is no way to prevent this, but we can control what we put out there and limit who has access to it.
Social networking sites are great fun but also great dangers. Posted pictures, videos and status updates can be viewed by friends and fiends alike. Unless you take a few simple steps to protect yourself.
Setting a good password is the first step. Easy for you to remember may be easy for someone else to guess, so stay away from tired options like children's names or birthdays. Instead, choose an obscure word that you are likely to remember, and then mix it up, literally. Use mixed case letters and numbers within the word. Take it further, by changing your password every three months or so.
