 Abstract— The vision of a landscape of heterogeneous web services deployed as encapsulated business software assets in the Internet is currently becoming a reality as part of the Semantic Web. When pro-active agents handle the context-aware discovery, acquisition, composition, management of applications services and data, ensuring the security if customers data become a principle task. In this paper we propose neoteric way web services and security. A methodology based on type-based information flow to control the security of dynamically computed data and their proliferation to other web services. The approach is based on the following trine guidelines: (1)The business and security concern of integrated web services are separated and building them independently.(2)Runtime modification of integrated web services.(3)Providing compartmentalization so that one service can not affect another. We are developing flight system to demonstrate the feasibility of our approach.

Abstract Grid is concerned with the sharing and coordinated use of diverse resources in distributed" virtual organizations. ¿ The dynamic and multi-institutional nature of these environments introduces challenging security issues that demand new technical approaches. In particular, one must deal with diverse local mechanisms, support dynamic creation of services, and enable dynamic creation of trust domains. As grid services are adopted and applied widely, as definition of an organizational boundary fade away in ...

The contemporary Web is heading towards its next stage of evolution. From a clump of unorganized information spaces, the Web is becoming more focused on the meaning of information that is a Semantic Web. Trust is an integral component in semantic web, allowing people to act under uncertainty and with the risk of negative consequences. In this paper we discussed trust management and its connection to the semantic web. We first discussed aspects of semantic web and trust management including defining trust and describing trust negotiations and then relationship of them. After that we explored how mechanisms of XML access control are used to protect the confidentiality, integrity and availability of ontologies in trust management.

ABSTRACT Web services provide many benefits for developing Web applications based on SOA (Service Oriented Architecture). However, there are some open issues such as security that need to be addressed by standard bodies and technology vendors in order for Web services to become a viable solution for building global service oriented architectures. As a result, much emphasis has been placed on the development of various high-level security standards and protocols, but in many cases the simplest application level attacks have been ignored by the developers. This article covers the dependency of Web services on XML, the various forms of XML-based attacks, famous standards about XML security and finally provides recommendation and countermeasures. This publication tends to provide an understanding of the challenges in integrating information security practices into Web services design and development.
