Requirements for a future EWS - Cyber Defence in the internet of the future

The emergence of new technologies and services as well as trillions of devices and petabytes of data to be processed and transferred in the Internet of the Future mean that we have to deal with new threats and vulnerabilities, in addition to handle the remaining old ones. Together with the rise of Cyber Warfare and the resulting impact on the environment means that we have to bring intelligence back to the network. Consequently, effective Cyber Defence will be more and more important. In this paper we will show that the proposed requirements for an Early Warning System are a main part of future Cyber Defence. Special attention is given on the challenges associated to the generation of early warning systems for future attacks on the Internet of the Future. The term Cyber War is used frequently but unfortunately with different intends. Therefore, we start with a definition of the term Cyber War focusing on security aspects related to the Internet of the Future, followed by an exemplification of a Cyber War, of its implications and the challenges associated to it. Then we proceed with an analysis of state of the art recent work that has been proposed on the topic. Additionally the weaknesses of these analyzed systems and approaches are presented. Finally we propose guidelines and requirements for future work which will be needed to implement a next generation early warning system for securing the Internet of the Future.
