"Consumer-based communications tools such as Hotmail, instant messaging and voice over IP are used by most employees, often from work and also as a way to transfer work materials to and from their PCs at home. "Most organisations will find themselves unable to completely block these services, for cultural, if not technical reasons, but security options are available to limit the risks that consumer communications services create."
