Nowadays organizations require an effective governance framework for their service-oriented architecture (SOA) in order to enable them to use a framework to evaluate their current state governance and determine the governance requirements, and then to offer a suitable model for their governance. Various frameworks have been developed to evaluate the SOA governance. In this paper, a brief introd...

this article presents a novel method and development paradigm that proposes a general template for an enterprise information structure and allows for the automatic generation and modification of enterprise workflows. this dynamically integrated workflow development approach utilises a conceptual ontology of domain processes and tasks, enterprise charts, and enterprise entities. it also suggests...

Ensuring a secure Service-Oriented Architecture implementation within an organisation is challenging. Without sound information security principles supporting a Service-Oriented Architecture implementation, the rate of success is low. The information security principles of identification, authentication, authorization, confidentiality, integrity, availability and accountability remain the same ...

As a matter of fact, SOA-based systems have a huge internal complexity due to plenty of services. On the one hand, this complexity enables and strongly supports the flexible alignment of the enterprise architecture with business processes. On the other hand, it requires a special management and control framework – provided by SOA Governance. For IT Governance, many accepted approaches exist. In...

service oriented architecture (soa) technology enables composition of large and complex computational units out of the available atomic services. implementation of soa brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. these challenges are mainly due to the dynamic nature of soa. soamay often need to ...

Automated services help enterprises create new value from reuse of software and resources and achieve new levels of agility through greater flexibility and lower cost structures. As services come in many flavors and guises they have differing characteristics. In this paper we describe the most necessary aspects and features of automated services. We also focus on the interplay of SOAs and Busin...

Over the past years, Service-oriented Architecture (SOA) Systems have been recognized more and more as a serious alternative to common monolithic systems for Enterprise Architectures (EA). An SOA provides a flexible means of effectively mapping business processes to IT processes. However, large IT systems require consistent leadership – IT Governance. For SOAs, governance faces new challenges. ...

the advantages and special characteristics of service oriented architecture and expansion of employing such architecture have brought security topics which are different in some cases from the security principles of traditional information systems. in this article our aim is the examination of various indices of security and the presentation of strategies for security in information systems by ...

certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...
