The service oriented architecture (SOA) is gaining more momentum with the advent of network services on the Web. A programmable and machine accessible Web is the vision of many, and might represent a step towards the semantic Web. However, security is a crucial requirement for the serious usage and adoption of Web services technology. This paper reviews existing work related to Web service secu...

Integrating applications and resources using Web Services increases the exposure of critical resources. Consequently, the introduction of Web Services requires that additional effort be spent on assessing the corresponding risks and establishing appropriate security mechanisms. This paper explains the main challenges for securing Web Services and summarizes emerging standards. The most importan...

the most secure web system out of the available generic and web security technology which can be used as a guideline for organizations building their web sites. The framework is designed to provide necessary security services, to address the known security threats, and to provide some cover to other security problems especially unknown threats. The requirements for the design are discussed whic...

Security and trust aspects, perceived as difficult to quantify, have been neglected in various service interactions. However, factors related to security and trust are in fact crucial in the overall value of service quality. A security ontology that enables a quantification of risks related to the usage of Semantic Web services in enterprise information systems was created to meet users’ requir...

Security of Web services is a major factor to their successful integration into critical IT applications. An extensive research in this direction concentrates on low level aspects of security such as message secrecy, data integrity, and authentication. Thus, proposed solutions are mainly built upon the assumption that security mechanisms are static and predefined. However, the dynamic nature of...
