Social networking sites (such as Facebook and Twitter), personal web pages, and blogs are notorious as public sources of personal information and uncensored opinions.

• Do not reveal personal details or confidential info online. Assume that anything you post to these websites is public and could potentially be used against you.
  •  A good rule of thumb is to only post information you would be willing to put on a banner displayed in a public place. 
  • Seemingly innocent information about your interests, family, or history could be used by hackers for identity theft, or by stalkers or social engineers.
    
    
• Also keep in mind that once you post something online, it can be very difficult to “take it back.” Even if you delete the information, copies can still exist on other computers, web sites, or in search engines.
