“…To support our security checking method, in the context of WebMov 4 project, we developed a tool known as RV4WS [17] [18] (Runtime Verification for Web Services) that checks a timed trace with respect to a set of security rules predefined by the syntax as introduced in Section 3.2. In this tool, a checking engine [19] (i.e., RVEngine) is developed independently in Java language and used as a library of the tool.…”

The cloud computing has provided customers with various services at its SaaS layer though, few work has been done on the security checking of messages exchanged between a customer and a service provider at SaaS so as to protect SaaS. In this paper we propose a validation model to investigate the SaaS security issue. Rather than installing a set of probes as we have done for the testing web services, in this model we introduce a validation service that plays the role of a firewall and protects our SaaS by verifying the correctness of messages with respect to a set of predefined security rules and forwarding them to their real destinations if they pass the verification or rejecting them otherwise. We develop a prototype model based on the tool known as RV4WS which was developed in our early study on web service runtime verification, as well as a checking engine RVEngine to verify our checking algorithm for the model. A survey on how to use this model for the services deployed on Google App Engine, Window Azure and Oracle Java Cloud Service is also presented.

“…The framework presented in [4] generates and executes automatically "online" tests for conformance testing of a composite of Web Services described in BPEL. This "online" approach was combined with passive testing, that verifies time traces with respect to a set of constraints in [3]. Both papers are limited to Web Services which are implemented according to BPEL specification.…”

Many business and scientific processes make extensive use of service-oriented architectures, using distributed services. These are often provided by third parties and are thus not under direct control of process owners. In this paper we discuss the issues of ensuring continuous and faithful execution of processes in distributed environments, focusing specifically on Web Services. Recently, we introduced a specification of Resilient Web Services, that makes current Web Services more robust, and a framework for the monitoring of Web Services, that allows detecting anomalies. In this paper, we describe alternative implementations of the framework for monitoring of Web Services. We also present possible approaches easing the deployment of Resilient Web Services: a framework consisting of tools deployable at the Web Service operator site enabling easy transformation of a regular Web Service into a Resilient Web Service, and a registry with notifications that decorates existing Web Services with resilient methods.

High dependence on web services and service-oriented architecture affects not only business solutions, but also scientific research. Web services may be delivered by third parties, and thus are candidates for outsourcing. However, they represent a source of risks, which can jeopardise the robustness of processes. Hence, there is a need for actions which can contribute to the mitigation of possible threats to the continuity of processes. In this paper, risk affecting processes are classified, followed by a discussion about particular changes stemming from web services. Three distinct approaches allowing improvements are described: a newly proposed web services monitoring framework supported by a software solution, the concept of resilient web services, which specifies new design requirements for web services, and digital preservation strategies, which apart from long-term benefits can support sustainability of currently running processes.
