Denial of service defence appliance for web services

Service-oriented architectures (SOAs), implemented using web services, seek to use open and interoperable standards to facilitate easier enterprise application integration, provide application flexibility and facilitate the dynamic composition of applications from component services. As with traditional distributed computing environments such as common object request broker architecture (CORBA), remote procedure call (RPC) and remote method invocation (RMI), the exposure of information resources via computer networks to remote users and applications requires that those resources be adequately protected.
