Don't give away too much information about yourself

Restricting what others can find out about you online:

  • Reduces the risk of identity theft
  • Reduces the risk of property theft
  • Prevents other people finding out things about your social life that you'd rather keep discreet

On social networks e.g. Facebook:

  • Use the privacy settings to restrict how much data others can see, especially people who aren't already your friends in the physical world (e.g. see

  • Don't post compromising photos of yourself or of your friends. Prospective employers use Facebook too.

  • If someone else tags you in a photo, have a look at it and remove the tag if you don't want others to know you're in it. (Or ask your friend to remove the photo itself.)

  • Contributions on discussion boards are often saved and can be read a long time after they've been made. An ill-advised comment may come back to haunt you!

Tell people only the bare essentials in your out-of-office emails. Use a vague statement like "I will be unable to respond to emails until the 20th" rather than "Off on holiday till the 20th" (which implies the house is empty!)
