Social Networks
Sharing information over the Internet is like shouting to a billion people. Everyone can see the pictures you post and read the information you enter, unless you protect yourself.
Social network services are generally insecure, though you can maintain some privacy with privacy settings. With over 300 social network services, including Facebook, Twitter and MySpace, most include instant messaging, peer-to-peer connectivity, and blog sharing. These sites provide the most accurate and easiest to use resource for obtaining information about people as well as spreading computer compromise by way of viruses and worms. Profiles and photos can be accessed by everyone from prospective employers to stalkers unless privacy settings are set. Do not provide personal or identifiable information in an open forum, and be sure not to click on any links as they may lead to compromise.
