The Internet of Things and Services is a rapidly growing concept that illustrates that the ever increasing amount of physical items of our daily life which become addressable through a network could be made more easily manageable and usable through the use of Services. This surge of exposed resources along with the level of privacy and value of the information they hold, together with the increase of their usage make for an augmentation in the number of the security threats and violation attempts that existing security systems do not appear robust enough to address. In this paper, the authors underline this increase in risk and identify the requirements for resources to be more resilient in this type of environment while keeping an important level of flexibility. In addition, the authors propose an architectural model of Self Managed Security Cell, which leverages on current knowledge in large scale security systems, information management and autonomous systems.

Self Managed Security Cell, a Security Model for the Internet of Things and Services

Currently, business requirements for rapid operational efficiency, customer responsiveness as well as rapid adaptability are driving the need for ever increasing communication and integration capabilities of the software assets. Service Oriented Architecture (SOA) is generally acknowledged as being a potential solution to expose finely grained pieces of software components on a network that are reusable and composable. Provisioning of business services for different business purposes may require the rapid assembly of their core functionality with different infrastructure capabilities and policies in different contexts. In this paper, the authors propose a SOA based governance model that permits to handle non functional requirements in a dynamic way.

A Governance Model for SOA

A fundamental ambition of grid and distributed systems is to be capable of sustaining evolution and allowing for adaptability ((F Losavio et al, 2002), (S Radhakrishnan, 2005)) Furthermore, as the complexity and sophistication of theses structures increases, so does the need for adaptability of each component One of the primary benefits of service oriented architecture (SOA) is the ability to compose applications, processes or more complex services from other services which increases the capacity for adaptation This document proposes a novel infrastructure composition model that aims at increasing the adaptability of the capabilities exposed through it by dynamically managing their non functional requirements

Secure & Rapid Composition of Infrastructure Services in the Cloud

The Web is evolving from a mere repository of information to a new platform for business transactions and information interchange. Large organizations are increasingly exposing their Business Processes through Web Services Technology for the large-scale development of software, as well as for the sharing of their services within and outside the organization. New paradigms for Software and Services Engineering such as the Software-asa-Service (SaaS) and the cloud computing model promise to create new levels of efficiency through large-scale sharing of functionality and computing resources. However, there are few academic works in this area and many gaps are still open. In this paper, we present a Business Process based on Semantics platform where services are executed from a SaaS perspective. The SITIO platform allows external developers to create add-on applications that integrate into the main SITIO application and are hosted on Cloud Computing infrastructure.

Adding semantics to software-as-a-service and cloud computing

Service-oriented infrastructures pose new challenges in a number of areas, notably with regard to security and dependability. BT has developed a combination of innovative security solutions and governance frameworks that can address these challenges. They include advances in identity federation; distributed usage and access management; context-aware secure messaging, routing and transformation; and (security) policy governance for service-oriented architectures. This paper discusses these developments and the steps being taken to validate their functionality and performance.

Securing business operations in an SOA

Currently, business requirements for rapid operational efficiency, customer responsiveness as well as rapid adaptability are driving the need for ever increasing communication and integration capabilities of the software assets. Enterprise Application Integration (EAI), which is the process of integrating enterprise systems with existing applications and in general distributed computing, have produced diverse integration techniques and approaches to undertake these challenges. This has brought the development of Service-Oriented Architecture (SOA) variants, which is partly supported by commonly accepted standards that ensure interoperability, sharing and reusability. As a result of this, a safer and faster level of return on investment (ROI) can be generated while inter-software communication and integration has becomes ever easier. In this paper we discuss ESB and evaluate the concept against already existing broker architectures and paradigms.

Enterprise Service Bus: An overview

One of the primary benefits of Service Oriented Architecture (SOA) [1] is the ability to compose applications, processes or more complex services from other services. As the complexity and sophistication of theses structures increases, so does the need for adaptability of each component. In recent years, a lot of effort has been put into improving the flexibility of these systems so that totally loose services can be integrated dynamically without imposing any architectural restrictions. This proposal presents a project to devise a novel model that aims at increasing the adaptability of the resources exposed through it by dynamically managing their non-functional requirements. To manage these non-functional properties, we aggregate the services required into what we define as a profile.
