Protecting web services with service oriented traceback architecture

Service oriented architecture (SOA) is a way of reorganizing software infrastructure into a set of service abstracts. In the area of applying SOA to Web service security, there have been some well defined security dimensions. However, current Web security systems, like WS-Security are not efficient enough to handle distributed denial of service (DDoS) attacks. Our new approach, service oriented traceback architecture (SOTA), provides a framework to be able to identify the source of an attack. This is accomplished by deploying our defence system at distributed routers, in order to examine the incoming SOAP messages and place our own SOAP header. By this method, we can then use the new SOAP header information, to traceback through the network the source of the attack. According to our experimental performance evaluations, we find that SOTA is quite scaleable, simple and quite effective at identifying the source.<br /

A service-oriented approach for model management

International audienceIn the Software Engineering (SE) domain, the Model Driven Engineering (MDE) paradigm focuses on using models as main software artifacts to provide a full description of software systems and on automating model manipulation with tools. Model management concerns a set of features allowing representing, creating, storing and manipulating models. Nowadays, the needs of models designers in terms of management process and products are diverse. Modeling tools are not complete because there is no consensus about models needs and uses. To remedy the heterogeneity and the functional limitations of models management tools, we propose a service-oriented approach for model management for the creation of modeling environments adapted to the needs of designers. The considered needs are related in two abstract levels: the operational and the organizational level

A SERVICE-ORIENTED APPROACH FOR INTERACTIVE COMPUTING

ABSTRACT The introduction of new technologies leads to a more and more complex interactive systems design. In order to describe the future interactive system, the human computer interaction domain uses specific models, design processes and tools in order to represent, create, store and manipulate models. The aim of our work is to provide a theoretical conceptual approach to facilitate the work of model designers and project managers by helping them in choosing processes, models and modeling environments adapted to their specific needs. This paper details the use of a service-oriented approach for model management. Our proposals are related to three different abstract levels: the operational level to choose the appropriate modelling tool, the organisational level to select a design process and the intentional level to define modelling goals. Keywords: HCI, model, service, model management, modeling tools, modeling services.
