An evolving workforce, reared on Web 2.0 technologies, is bringing a different perspective to how computers are used within an organization. With a mindset that is highly tuned to sharing information and applications, and emailing and messaging friends, the new “employee 2.0”
is redefining how individuals interact with the internet and the IT environment as a whole. While the new internet technologies they are exploiting can bring business value in helping employees communicate, share files and work collaboratively online, they also pose a range of new threats. Internet-enabled applications such as Instant Messaging (IM), peer-to-peer (P2P) file-sharing applications and Voice over Internet Protocol (VoIP) services have been causing concern for some time. A Sophos online poll asking IT administrators what kind of software applications they would like to prevent their users from being able to access and use shows that even by late 2006 they recognized the need to be able to exert more control and to prevent users from installing and using unwanted applications.
