Requirements for Resilient Information and Communication Technology

Information and communication technology (ICT) is indispensable for today´s society and business environment. The continuous usage of ICT is an essential requirement of the society, especially during a disaster. Besides that, resilient ICT is desirable not only for almost any business environment but also for business continuity planning of such businesses in order to make their internal ICT resilient. We first discuss the requirements of resilient ICT based on surveys of the latest technologies that aim to improving resiliency, such as virtualization of servers and networks. We then argue that it is necessary to consider two levels of ICT resiliency. Additionally, we propose how to select evaluation means of the technologies for facilitating resiliency, and operational frameworks for achieving resiliency.
