“…Their approach only applies to the service composition level and does not support others due to the lack of means for quantification. Two approaches that support the manipulation of orchestrations using AOP-style means for quantification are Charfi's and Mezini's work on AO4BPEL [17] and Narendra et al's work et al [18]. Both are geared towards the modification of web service compositions, the former at the orchestration level, the latter at the service implementation level.…”

Abstract-Existing approaches to the adaptation of workflows over web services fall short in two respects. First, they only provide, if ever, limited means for taking into account the execution history of a workflow. Second, they do not support adaptations that require modifications not only at the service composition level but also at the levels of interceptors and service implementations. This is particular problematic for the enforcement of security properties over workflows: enforcing authorization properties, for instance, frequently requires execution contexts to be defined and modifications to be applied at all these abstraction levels of web services.We present two main contributions in this context. First, we introduce workflow adaptation schemas (WAS), a new notion of generic protocol-based workflow adapters. WAS enable the declarative definition of adaptations involving complex service compositions and implementations. Second, we present two realworld security issues related to the use of OAuth 2.0, a recent and widely used framework for the authorization of resource accesses. As we motivate, these security issues require historybased adaptations over different abstraction levels of services. We then show how to resolve these issues using WAS.

“…Each time a workflow derivation event is detected it is either possible to choose an already defined worklet or define a new one. AO4BPEL [3] is an aspect-oriented extension to BPEL that allows describing workflow´s crosscutting behaviour. The extension comprises a language that is used to declare aspects and an execution engine that is responsible of weaving core workflows with workflow aspects.…”

Abstract. Workflow plays a major role in nowadays business and therefore its requirement elicitation must be accurate and clear for achieving the solution closest to business's needs. Due to Web applications popularity, the Web is becoming the standard platform for implementing business workflows. In this context, Web applications and their workflows must be adapted to market demands in such a way that time and effort are minimize. As they get more popular, they must give support to different functional requirements but also they contain tangled and scattered behaviour. In this work we present a model-driven approach for modelling workflows using a Domain Specific Language for Web application requirement called WebSpec. We present an extension to WebSpec based on Pattern Specifications for modelling crosscutting workflow requirements identifying tangled and scattered behaviour and reducing inconsistencies early in the cycle.

“…For instance, Courbis and Finkelstein [6] proposed to weave aspects into web service orchestrations. Service orchestrations, in particular using the language BPEL, have also been extended with aspect support by Charfi and Mezini [4]. Still, not much has been done to date to provide support for multilevel horizontal and vertical service compositions or for enforcing security mechanisms at multilevel service composition in the presence of aspects.…”

Abstract. Due to today's rapidly changing corporate environments, business processes are increasingly subject to dynamic configuration and evolution. The evolution of new deployment architectures, as illustrated by the move towards mobile platforms and the Internet Of Services, and the introduction of new security regulations (imposed by national and international regulatory bodies, such as SOX 4 or BASEL 5 ) are an important constraint in the design and development of business processes. In such a context, it is not sufficient to apply the corresponding adaptations only at the service orchestration or at the choreography level; there is also the need for controlling the impact of new security requirements to several architectural layers, specially in cloud computing, where the notion of Platforms as Services and Infrastructure as Services are fundamental. In this paper we survey several research questions related to security cross-domain and cross-layer security functionality in Service Oriented Architectures, from an original point of view. We provide the first insights on how a general service model empowered with aspect oriented programming capabilities can provide clean modularization to such cross-cutting security concerns.Keywords: SOA, Evolution, AOP, REST, Security Motivation and OutlineService-oriented architectures (SOAs) constitute a major architectural style for large-scale heterogeneous infrastructures and applications that are built from loosely-coupled, well-separated services and are subject to dynamic configuration, manipulation, and evolution.
