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.

Security Standards

Security is one of the largest challenges facing the development of a Service-Oriented Architecture (SOA). This is due to the fact that SOA security is the responsibility of both the service consumer and service provider. In recent years, many solutions have been implemented, such as the Web Services Security Standards, including WS-Security and WS-SecurityPolicy. However, those standards are insufficient for the promising new generations of Web 2.0 applications. In this research, we describe an Intelligent SOA Security (ISOAS) framework and introduce four of its services: Authentication and Security Service (NSS), the Authorization Service (AS), the Privacy Service (PS) and the Service of Quality of Security Service (SQoSS). Furthermore, a case study is presented to examine the behavior of the described security services inside a market SOA environment.

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.

Service-oriented architecture (SOA) is widely used, which has fueled the rapid growth of Web services and the deployment of tremendous Web services over the last decades. It becomes challenging but crucial to find the proper Web services because of the increasing amount of Web services. However, it proves unfeasible to inspect all the Web services to check their quality values since it will consume a lot of resources. Thus, developing effective and efficient approaches for predicting the quality values of Web services has become an important research issue. In this paper, we propose UIQPCA, a novel approach for hybrid User and Item-based Quality Prediction with Covering Algorithm. UIQPCA integrates information of both users and Web services on the basis of users’ ideas on the quality of coinvoked Web services. After the integration, users and Web services which are similar to the target user and the target Web service are selected. Then, considering the result of integration, UIQPCA makes predictions on how a target user will appraise a target Web service. Broad experiments on WS-Dream, a web service dataset which is widely used in real world, are conducted to evaluate the reliability of UIQPCA. According to the results of experiment, UIQPCA is far better than former approaches, including item-based, user-based, hybrid, and cluster-based approaches.

Workflow-based web service compositions (WB-WSCs) is one of the main composition categories in service oriented architecture (SOA). Eflow, polymorphic process model (PPM), and business process execution language (BPEL) are the main techniques of the category of WB-WSCs. Due to maturity of web services, measuring the quality of composite web services being developed by different techniques becomes one of the most important challenges in today’s web environments. Business should try to provide good quality regarding the customers’ requirements to a composed web service. Thus, quality of service (QoS) which refers to nonfunctional parameters is important to be measured since the quality degree of a certain web service composition could be achieved. This paper tried to find a deterministic analytical method for dependability and performance measurement using Colored Petri net (CPN) with explicit routing constructs and application of theory of probability. A computer tool called WSET was also developed for modeling and supporting QoS measurement through simulation.

The realisation of Service-Oriented Architecture (SOA) to communicate data between systems running on different platforms lack an organised framework to capture the essential elements required for successful interoperability between web applications and their services. In this work, a SOA for Data Interoperability in Web Applications (SOADIWA) was designed. The architecture of SOADIWA was based on five layers, namely Web Application Layer (WAL), Quality of Service Assurance Certifier Layer (QoSACL), Web Service Layer (WSL), Visualization Input Layer (VIL) and Visualization Output Layer (VOL). In WAL, the Service Requester (SR) initiates a request for data from the Service Provider (SP) through the QoSACL to provide appropriate website via WSL for rendering of services which must be accepted, processed and returned for a particular need in VIL. The requested data is filtered in VIL for data exploration and analysis in VOL using context-sensitive visualization techniques. The purpose of QoSACL is to check and verify the claims made by the SP about its quality of service. This enabled the SR to choose the service that satisfied its needs. The implementation comprised of Java Script, Microsoft Visual Studio 2017 and NuGet packages; while the experiment was simulated on LoadUI pro application. Standard metrics such as Optimal Performance (OP) and Phased Effort Distribution (PED) were developed to test SOADIWA. These results conformed to basic web service interoperability. The work led to the integration of a host of techniques towards the creation of a novel tool that is useful in web domain using SOA approach.

The use of firewall has been widespread in all the emerging technologies such as Service Oriented Architecture, web services, cloud computing and so on. The term security itself is the most important task that has to be maintained in the real-time applications. Policies are enrolled in the security of the firewall where the quality of policies is to be maintained. The network administrator defines the policy as a rule. Managing the firewall policies, maintaining the risk analysis and also the conflicting nature that arise in the network, lack of systematic analysis mechanisms and tools used are often error prone. The distributed firewall is used to overcome the shortcomings of the traditional firewall. In this paper we represent a set of techniques such as, rule-based segmentation technique to identify the policy anomalies and effectively derive the anomaly resolution. Grid-based visualization technique, provide the policy anomaly information in a grid form, which helps in identifying the policy conflicts and finally the techniques to resolve the conflicts and the redundancy that arise in a single- or multi-firewall environment. We also discuss about the implementation of the visualization-based firewall policy analysis tool called Firewall Anomaly Management Framework (FAME), where all the techniques are used in a single tool and an approach to resolve the anomalies in an effective and efficient way.
