The SERSCIS approach aims to support the use of interconnected systems of services in Critical Infrastructure (CI) applications. The problem of system interconnectedness is aptly demonstrated by 'Airport Collaborative Decision Making' (A-CDM). Failure or underperformance of any of the interlinked ICT systems may compromise the ability of airports to plan their use of resources to sustain high levels of air traffic, or to provide accurate aircraft movement forecasts to the wider European air traffic management systems. The proposed solution is to introduce further SERSCIS ICT components to manage dependability and interdependency. These use semantic models of the critical infrastructure, including its ICT services, to identify faults and potential risks and to increase human awareness of them. Semantics allow information and services to be described in a way that makes them understandable to computers. Thus when a failure (or a threat of it) is detected, SERSCIS components can take action to manage the consequences, including changing the interdependency relationships between services. In some cases, the components will be able to take action autonomously, e.g., to manage 'local' issues such as the allocation of CPU time to maintain service performance, or the selection of services where there are redundant sources available. In other cases the components will alert human operators so they can take action instead. The goal of this paper is to describe a Service Oriented Architecture (SOA) that can be used to address the management of ICT components and interdependencies in critical infrastructure systems.

“…There exists a limit in the number of processes created by the firewall. Currently, the kind of critical information systems exposed to attacks are of much interest in literature (e.g., MAFTIA [1], CRUTIAL [23] or SITAR [24]). However, consider that we do not pretend to model intricacies of these kind of systems but only to exemplify the use of the Resilience package.…”

Modelling system security is not common practise in software projects yet. Among other problems, there is not a widely accepted methodology which unifies the actual heterogeneity of security issues when addressing a whole security specification. Certainly, the reality is even worse since there is not an accepted or standard common notation for carrying out the security specification. In this work, we study how modelling security issues, specifically resilience, could be integrated in the MARTE-DAM framework, which allows the expression of performance and dependability requirements in UML models. We base this claim on the close relationship between security and dependability. Indeed, MARTE proposes a framework for non-functional properties specification (NFP), while DAM exploits it for dependability purposes. So, our goal is to take advantage of the common NFP framework while the dependability and security concerns are modelled in a unified view. On the other hand, we consider that the resulting security specification will be useful for developing model in which security related properties, such as availability, will be analysed. We will clarify these claims by means of an example.
