Ict Security

The work presents the essence of problems appearing in the ICT security management process in the context of systems characterized by significant dynamics of configuration and heterogeneity of resources both in the hardware and software layer. Basic differences in security management in systems with traditional centralized and monolithic architecture as well as in systems with service-oriented architecture have been presented. A layered reference model for service-oriented systems taking account of the basic goals of ICT security for dynamic information systems has been discussed. The basic assumptions of the multi-agent ICT security analysis system in service-oriented systems as well as the results of the safety analysis, including the correlation between events observed in low and high layers of the reference model have been discussed.

In this paper the authors present the design and software development of an E-learning system based on a multi-agent (MAS) architecture. The multi-agent architecture is established on the client-server model. The MAS architecture is combined with the Dynamic Content Manager (DCM) model of E-learning developed at Bergen University College, Norway. The authors first present the quality requirements of the system before they describe the architectural decisions taken. They then evaluate and discuss the benefits of using a multi-agent architecture. Finally, the MAS architecture is compared with a pure service-oriented architecture (SOA) to observe that a MAS architecture has a lot of the same qualities as this architecture, in addition to some new ones.

Automated Support

The Service-Oriented Architecture paradigm (SOA) is commonly applied for the implementation of complex, distributed business processes. The service-oriented approach promises higher flexibility, interoperability and reusability of the IT infrastructure. However, evaluating the quality attribute security of such complex SOA configurations is not sufficiently mastered yet. To tackle this complex problem, the authors developed a method for evaluating the security of existing service-oriented systems on the architectural level. The method is based on recovering security-relevant facts about the system by using reverse engineering techniques and subsequently providing automated support for further interactive security analysis at the structural level. By using generic, system-independent indicators and a knowledge base, the method is not limited to a specific programming language or technology. Therefore, the method can be applied to various systems and adapt it to specific evaluation needs. The paper describes the general structure of the method, the knowledge base, and presents an instantiation aligned to the Service Component Architecture (SCA) specification.

The Media

The recent economic, organizational and technological transformations are motivating developing countries to adopt electronic government applications. The main objective of the e-government project in Sudan is “to achieve a society based on a strong base of industry knowledge in which all segments of the media access to information that leads to the distribution, publication and use of information as widely as a whole contributes to the achievement of economic growth, increase employment and raise the rates and quality of production in all sectors and poverty eradication. However, the project has been based on the use of a client-server architecture that has many limitations. This chapter provides a multiagent service oriented architecture for the implementation of the project based on a thorough review of project documents and implementation reports.

Conceptual Work

AbstractThis paper provides an overview about the conceptual work performed by the VDI/VDE GMA working group 7.21 towards the specification of a reference model for Industrie 4.0 service architectures. It focuses on the conceptual design of service-oriented architecture (SOA) relying upon the “I40 component” as a core basic concept across the whole value network. Furthermore, the paper discusses the relevance of reference models of the Internet of Things and Services as a foundation.

Cloud computing has recently received considerable attention, as a promising approach for delivering Information and Communication Technologies (ICT) services as a utility. In the process of providing these services it is necessary to improve the utilization of data centre resources which are operating in most dynamic workload environments. Datacenters are integral parts of cloud computing. In the datacenter generally hundreds and thousands of virtual servers run at any instance of time, hosting many tasks and at the same time the cloud system keeps receiving the batches of task requests. It provides services and computing through the networks. Service Oriented Architecture (SOA) and agent frameworks renders tools for developing distributed and multi agent systems which can be used for the administration of cloud computing environments which supports the above characteristics. This paper presents a SOQM (Service Oriented QoS Assured and Multi Agent Cloud Computing) architecture which supports QoS assured cloud service provision and request. Biomedical and geospatial data on cloud can be analyzed through SOQM and has allowed the efficient management of the allocation of resources to the different system agents. It has proposed a finite heterogeneous multiple vm model which are dynamically allocated depending on the request from biomedical and geospatial stakeholders.
