Social networking sites such as Facebook, Twitter and LinkedIn are becoming more and more popular. The nature of these sites creates security risks, so you should always be cautious when using them.
These types of sites promote personal connections and communications, and require you to provide a certain amount of personal information.
However, the more information available, the easier it becomes for others to take advantage of your identity. In some cases, criminals could fraudulently exploit this to obtain products and services in your name.
Personal information could also be used to conduct a 'social engineering attack'. Predators may form relationships online and then convince unsuspecting individuals - often young people - to meet them in person, which could lead to a dangerous situation.
