This year's edition of the World Information Society Report 2007 notes that growth in the global Information Society is not without risks and the Report examines the potential pitfalls of growth in the rise of online fraud, other risks and threats to cybersecurity. The expansion of the Internet is opening up many new opportunities for criminals to exploit online vulnerabilities and commit criminal acts or attack countries' critical infrastructures.

Threats in cyberspace are evolving rapidly and deserve greater attention for several reasons. The evolution of telecommunication networks towards Next-Generation Networks (NGN) with decentralized intelligence at the edges of the network could raise new security issues. The capacity and speed of networks are increasing, accelerating the transmission of malicious software alongside other Internet traffic. Transmission and encryption protocols are also constantly being updated. Meanwhile, convergence offers new opportunities for 'cross-infection', with the problems of one access device feeding into other ICTs.

Viruses, spyware, phishing, identity theft, denial-of-service attacks and zombie botnets are endangering cyberspace and jeopardising the very future of the Internet. According to one source, spam and other exploitation now account for up to 90 per cent of all email traffic over the Internet. Spam has now mutated from a general annoyance to a broader cybersecurity threat, acting as a platform for many other types of scams (see Figure).

Chapter five, "Challenges to building a safe and secure Information Society" of the World Information Society Report 2007 examines these issues.
