| Abstract | This paper addresses the potential of mathematical modelling in support of the classical security risk assessment and treatment approach. Classical security risk assessment and control selection is strongly based on expert judgment. Within the context of large scale system implementation in air traffic management, there is only a limited availability of resources during the system engineering phase. From that perspective an alternative approach based on system engineering artefacts is highly desirable. Furthermore, robust mathematical modelling can support in the verification of security risk mitigation decisions and provide a means to address trade-off decisions between a variety of different security controls. The research reported in this paper is based on game-theoretic concepts and graph theory. The security control selection problem is modelled as a multi-objective optimization problem. Two interwoven models are developed for addressing the security risk assessment problem of a system. The internal model describes the actual system and its parameters, while the external model is used to describe possible threat scenarios. These models and the modelling technique is instantiated for a simple airport context, and the essential building blocks of the method are discussed on this example. The work reported in this paper shows the general feasibility of a mathematically founded approach to security risk assessment in large-scale system engineering. The proposed modelling approach forms the basis for the development of a dynamic security risk management capability as part of a recently started European research project on global air traffic management security. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
