International business demands seamless service and IT-infrastructure throughout the entire supply chain. However, dependencies between different parts of this vulnerable ecosystem form a fragile web. Assessment of the financial effects of any abnormalities in any part of the network is demanded in order to protect this network in a financially viable way. Contractual environment between the actors in a supply chain, different business domains and functions requires a management model, which enables a network wide protection for critical infrastructure. In this paper authors introduce such a model. It can be used to assess financial differences between centralized and decentralized protection of critical infrastructure.As an end result of this assessment business resilience to unknown threats can be improved across the entire supply chain.
Cloud computing has been a topic of keen interest in recent years, having been referred to as "the emerging paradigm for the last five years", "the most promising computational platform" and "the prevailing technique for next ten years". There has been a lot of discussion as to what new opportunities it can bring to markets, what benefits it can offer, and what system development possibilities it enables for software development. In this paper we discuss cloud computing in a military context. We define the key features and characteristics of the cloud in public authority environments. We address the most essential problems and obstacles to be considered before the benefits of cloud computing can be fully enabled therein. As a solution to problems with the adoption cloud computing in public authority environments, we propose a new service model called Knowledge Management as a Service, which also improves usability. The discussion and views presented in this paper can be adopted in any organization with doubts concerning the sensitive and classified contents of current ICT systems in cloud computing.
