Wireless Networks and Critical Information Infrastructure

The dynamic development of economy greatly benefits from the penetration of information and communication technology. The rapid expansion of the use of portable info communication devices brings along the expansion of the supporting infrastructure. The explosive growth of wireless networks blurs the boundaries the simple wired and mixed computer networks. The infrastructure operators should focus on the complex and protected, fully comprehensive network security, instead of managing and protecting individual network segments. Today it is impossible to imagine an up to date workstation, which were not supported by some up to cutting-edge solution. This is the same in the critical information infrastructures (CII). The infrastructure operators are able to adequately protect their wired networks from unauthorised external attacks. On the other hand wireless networks begin a new epoch in network and information security. In this paper we introduce the wireless networking trends in Budapest, based on our decade-long survey. We also evaluate this data in the light of the known wireless attack types.
