Facebook is a social networking site. Facebook is a social networking website that is operated and privately owned by Facebook, Inc. Users can add friends and send them messages, and update their personal profiles to notify friends about themselves. Additionally, users can join networks organized by city, workplace, and school or college.


The website's membership was initially limited by the founders to Harvard students, but was expanded to other colleges in the Boston area, the Ivy League, and Stanford University. It later expanded further to include (potentially) any university student, then high school students, and, finally, to anyone aged 13 and over. The website currently has more than 400 million active users worldwide.

Facebook has a number of features with which users may interact. They include the Wall, a space on every user's profile page that allows friends to post messages for the user to see; Pokes, which allows users to send a virtual "poke" to each other (a notification then tells a user that they have been poked); Photos, where users can upload albums and photos; and Status, which allows users to inform their friends of their whereabouts and actions. Depending on privacy settings, anyone who can see a user's profile can also view that user's Wall. In July 2007, Facebook began allowing users to post attachments to the Wall, whereas the Wall was previously limited to textual content only.

Facebook and security

Using the default settings on Facebook isn't enough to protect you from identity theft. Researchers examined the profiles of 200 Facebook users and found that 75 per cent of them allowed other Facebook visitors to see their full profiles, regardless of whether they were friends or not. By allowing their personal details to be seen by strangers, these Facebook members are putting themselves at risk of identity theft.

Many of them may not have realised their profiles had become insecure, because when you join Facebook, your profile is opened up to all members of that network, it is then up to you to adjusted the security settings. But they should make this known to people while joining!

The potential security risks of Facebook have been in the news recently, also the use of Facebook in the workplace has being a particularly contentious issue.

The Trades Union Congress called for employers to set down guidelines concerning the acceptable use of the internet in the workplace. In August, Sophos found that a high proportion of Facebook users were accepting friend requests from complete strangers.
