Threats Analysis and Prevention for Grid and Web Service Security

In order to enhance the security level and prevent the threats in Grid interacting with Web service environment, based on discriminating participant actors during the procedure of computation, a new threat classification method is proposed before corresponding threats model is introduced. Furthermore, we illustrate how basic security services and tools should interact with each other to provide an attack-resilient multilayer protection methodology in a service-oriented architecture. As a result, such threats analysis can be further utilized as the basis of proper security services design and operational procedures development.
