SSOAM: Automated Security Testing Framework for SOA Middleware in Banking Domain

In the banking domain, a high level of security must be considered and achieved to prevent a core-banking system from vulnerabilities and attackers. This is especially true when implementing Service Oriented Architecture Middleware (SOAM), which enables all banking e-services to be connected in a unified way and then allows banking e-services to transmit and share information using simple Object Access Protocol (SOAP). The main challenge in this research is that SOAP is designed without security in mind and there are no security testing tools that guarantee a secure SOAM solution in all its layers. Thus, this paper studies and analyzes the importance of implementing secure banking SOAM design architecture and of having an automated security testing framework. Therefore, Secure SOAM (SSOAM) is proposed, which works in parallel with the banking production environment. SSOAM contains a group of integrated security plugins that are responsible for scanning, finding, analyzing and fixing vulnerabilities and also forecasting new vulnerabilities and attacks in all banking SOAM layers.

Performance and Challenges of Service-Oriented Architecture for Wireless Sensor Networks.

Wireless Sensor Networks (WSNs) have become essential components for a variety of environmental, surveillance, military, traffic control, and healthcare applications. These applications face critical challenges such as communication, security, power consumption, data aggregation, heterogeneities of sensor hardware, and Quality of Service (QoS) issues. Service-Oriented Architecture (SOA) is a software architecture that can be integrated with WSN applications to address those challenges. The SOA middleware bridges the gap between the high-level requirements of different applications and the hardware constraints of WSNs. This survey explores state-of-the-art approaches based on SOA and Service-Oriented Middleware (SOM) architecture that provide solutions for WSN challenges. The categories of this paper are based on approaches of SOA with and without middleware for WSNs. Additionally, features of SOA and middleware architectures for WSNs are compared to achieve more robust and efficient network performance. Design issues of SOA middleware for WSNs and its characteristics are also highlighted. The paper concludes with future research directions in SOM architecture to meet all requirements of emerging application of WSNs.

An integrated remote monitoring platform towards Telehealth and Telecare services interoperability

Software platforms focused on the healthcare monitoring sector have recently attained a great penetration in the ICT market and they certainly constitute a key contributor to the improvement of the elderly people’s quality of life and the reduction of healthcare costs. It is of great importance that the platform allows for the simultaneous health, mental and psychological status evaluation of an elderly person. However, the integration of vital signs monitoring (Telehealth) with behavioral analysis based on home care sensors (Telecare) has not yet been established at a large scale. We describe the design and implementation of such platform that enables the deployment of services to follow-up the patient’s health status based on a set of monitored parameters per disease and to profile user’s habits and diagnose deviations from their usual activities. A key aspect of the platform is its Service Oriented Architecture middleware that collects data from heterogeneous Telecare and Telehealth gateways and provides the upper service layers with a unified and standards compliant message. In this way, an integrated view of Telehealth and Telecare data and alerts is made possible into a backend Web Portal where clinicians and operators have access to.

Integrated open geospatial web service enabled cyber-physical information infrastructure for precision agriculture monitoring

Various wireless and wired sensors serve vital functions in situational awareness for precision agriculture (PA) monitoring. Achieving the seamless integration of these heterogeneous sensors into information systems to achieve interoperability is challenging. To solve this problem, an integrated open geospatial web service-enabled cyber-physical infrastructure was proposed in this study to acquire, integrate, process, and distribute monitoring information from the physical sensor space of the PA system over the World Wide Web space. This infrastructure was designed as a service-oriented architecture middleware between heterogeneous physical sensors and different PA information clients. In particular, sensor web enablement and web processing services were utilized. Ten types of distributed agricultural sensors were deployed in Baoxie field, Wuhan City, and two different experiments were conducted to verify the proposed cyber-physical infrastructure. Results demonstrated that this infrastructure was capable of handling data and analyses in sensor-based PA monitoring. The proposed approach was then compared with existing typical PA infrastructures. Results indicated that the proposed cyber-physical infrastructure provided interoperable access for heterogeneous sensors, data, and algorithms. The proposed infrastructure thus provides a new feasible method for information system design in PA.

A device-level service-oriented middleware platform for self-manageable DC microgrid applications utilizing semantic-enabled distributed energy resources

Dynamic and adaptable integration of Distributed Energy Resources (DERs) into novel power system assets, such as microgrids, is one of the key prerequisites for accelerated Smart Grid deployment. By using standardized network interfaces and semantic descriptions for remotely controllable DERs, it is possible to develop intelligent microgrid applications capable of dealing with dynamic loads and intermittent DER power production. IEC 61850 standard has been accepted as one of the prime movers of successful and interoperable Smart Grid communication and integration. Although primarily being applied to the substation automation, IEC 61850 now provides semantic definitions for DER devices allowing it to be applied to expert microgrid application development. The current IEC 61850 middleware definition cannot cope with certain Smart Grid requirements such as support for autonomous microgrid applications with DER plug-and-play capability. These issues could be solved by integrating the device-level Service Oriented Architecture (SOA) paradigm into IEC 61850 applications. Developing a device-level SOA middleware platform based on IEC 61850 principles could significantly facilitate standards-compliant DER integration and accelerate microgrid deployment. A new middleware platform for microgrid applications is proposed. It is based on integrating device-level SOA design principles into IEC 61850 applications in order to fulfil dynamic microgrid management requirements.

Web Portal Integration Architecture Approaches

Enterprise Modelling with Web portal integration architecturerequires investment of advanced architectural thinking into definition of services before any development of services or service consumers can begin. Service Oriented Architecture (SOA)is gradually replacing monolithic architecture as the premier d sign principle for new business applications with its inherently systematic nature andcapability. Earlier efforts of notable styles of SOA such as CORBA and XATMI have failed to be adopted as main stream projects because of demanding design process requirement with sense -making activities and even have been residing with the modern SOA or Web services middleware. In this paper it is aimed to incorporate sensemaking design activities with the proposed semantic web service based architecture. This paper tries to tackle the above problem by proposing a service -oriented architecture for web data and service integr ation. A gen-Spec architectural pattern has been suggested and adopted in order to tackle theproblem. Firstly, it proposes a service-oriented platform independent architecture andSecondly, it presents a specific deployment of such architecture for data and service integratio n on the web using semantic webservices implemented with the WSMO (Web Services Modeling Ontology).

Ubiquitous Air Quality Monitoring System with Service Oriented Architecture Middleware

We have been developing AirScope, an event-based air quality monitoring system, since 2008 and regularly add new features to it. The first version of AirScope is up and running on desktop and mobile platforms; however, it is limited in its capability to assimilate new sensors and components from other parties. In order to add third party components, extensive manual integration is required. In this paper, we propose using Enterprise Service Bus (ESB) as AirScope’s data communication and exchange channel. ESB is a centralized, logical, architectural component that operates in a distributed, heterogeneous environment to facilitate the requirements of a highly scalable, faulttolerant, service-messaging framework. ESB also secures delivery of messages by enforcing authentication, authorization, nonrepudiation, and confidentiality.

Pervasive Smart Spaces and Environments: A Service-Oriented Middleware Architecture for Wireless Ad Hoc and Sensor Networks

In the twenty-first century, the impact of wireless and ubiquitous technologies is changing the way people perceive and interact with the physical world. These communication paradigms promise to change and redefine, in a reasonably short period of time, the most common way of our everyday living. The continuous advances in the field of Wireless Sensor Networks and their direct application in Smart Spaces are clear examples of it. However, in order for this kind of new generation infrastructures to have a large-scale dissemination, there are still some open issues to tackle. In this way, this paper presents nSOM, a service-oriented framework based on sensor network design that provides internetworking services with the Internet cloud. This lightweight middleware architecture implements an agent-based virtual sensor service approach which is a compact semantic knowledge management scheme based on a dynamic composition model.

Uranus: A Middleware Architecture for Dependable AAL and Vital Signs Monitoring Applications

A Middleware Architecture for Wireless Sensor Networks Using Secure Web Services

This paper proposes a service oriented middleware architecture for wireless sensor networks (WSNs) with security requirements. The web services standards XML, SOAP and WSDL are used for network communication. For the WSN security the WS-Security specification is applied, using cryptography and authentication for the data traffic. A prototype developed in Java language tests the proposed architecture. The results obtained show the correct functioning of the middleware, which facilitates the development of secure applications for WSNs.

Online Diarization of Streaming Audio-Visual Data for Smart Environments

For an environment to be perceived as being smart, contextual information has to be gathered to adapt the system's behavior and its interface towards the user. Being a rich source of context information speech can be acquired unobtrusively by microphone arrays and then processed to extract information about the user and his environment. In this paper, a system for joint temporal segmentation, speaker localization, and identification is presented, which is supported by face identification from video data obtained from a steerable camera. Special attention is paid to latency aspects and online processing capabilities, as they are important for the application under investigation, namely ambient communication. It describes the vision of terminal-less, session-less and multi-modal telecommunication with remote partners, where the user can move freely within his home while the communication follows him. The speaker diarization serves as a context source, which has been integrated in a service-oriented middleware architecture and provided to the application to select the most appropriate I/O device and to steer the camera towards the speaker during ambient communication.

A grid middleware for data management exploiting peer-to-peer techniques

In this paper, we describe a service-oriented middleware architecture for Grid environments which enables efficient data management. Our design introduces concepts from Peer-to-Peer computing in order to provide a scalable and reliable infrastructure for storage, search and retrieval of annotated content. To ensure fast file lookups in the distributed repositories, our system incorporates a multidimensional indexing scheme which serves the need for supporting both exact match and range queries over a group of metadata attributes. Finally, file transfers are conducted using GridTorrent, a grid-enabled, Peer-to-Peer mechanism that performs efficient data transfers by enabling cooperation among participating nodes and balances the cost of file transfer among them. The proposed architecture is the middleware component used by the GREDIA project, in which both media and banking partners plan to share large loads of annotated content.

The Last Inch at 70 Miles Per Hour

More recently, personal area network connectivity in vehicles has evolved, bringing with it a new set of challenges and associated opportunities. Principal among these challenges is the last-inch problem. The telecommunications industry uses the term last mile to refer to the challenge of bringing high-bandwidth connectivity to individual homes. We use the term last inch to characterize the challenges of delivering computing services through in-vehicle human-machine interfaces (HMIs) to users who are sometimes driving at speeds upwards of 70 miles per hour. We focus on the nonfunctional requirements of security, privacy, usability, and reliability (SPUR)). These attributes both encompass safety concerns and offer insight into the consumer experience. We took the SPUR requirements into account in designing our vehicle consumer services interface (VCSI), a service-oriented middleware architecture that we've implemented in a demonstration vehicle
