Cyberspace comprises IT networks, computer resources, and all the fixed and mobile devices connected to the global Internet. A nation’s cyberspace is part of the global cyberspace; it cannot be isolated to define its boundaries since cyberspace is borderless. This is what makes cyberspace unique. Unlike the physical world that is limited by geographical boundaries in space—land, sea, river waters, and air—cyberspace can and is continuing to expand. Increased Internet penetration is leading to growth of cyberspace, since its size is proportional to the activities that are carried through it.

Nations are investing heavily in their ICT infrastructures with a view to providing higher bandwidths, integrate national economies with the global marketplace, and to enable citizens or “netizens” to access more and more e-services.

Given the security problems, there is increased emphasis on, and investment in, the security of cyber infrastructure. Core Internet protocols are insecure, and an explosion of mobile devices continues to be based on the same insecure systems. This is adding up to increased usage of the Internet in more vulnerable cyberspace.
