而且，必须同时了解SOA安全服务实现的大部分内容。
And, counter-intuitively, much of the SOA security services implementation must be understood simultaneously.
当使用EJB安全模型调用服务实现、会话ejb时，将实现授权处理。
Authorization is achieved when the service implementation, session EJB, is called using the EJB security model.
通过内部使用ltpa令牌，Web服务实现获得了在支持大量工具的IBM环境中传播安全上下文的简单方法。
Using LTPA tokens internally, Web services implementations gain a lightweight way to propagate security context in an IBM environment with great tools support.
这个主体是作为J2EE上下文来建立的，所以我们可以确保在服务实现中定义的安全性约束在分派组件之前得到满足。
The principal is established as the J2EE context so that we can ensure that the security constraints that are defined on the service implementation are met before dispatching the component.
如果网关和服务提供者之间的传输支持SOAP和Web服务安全，网关甚至可以使用WS - Security将上下文传回到服务实现。
The gateway can even use WS-Security to pass the context back to the service implementation, if the transport between the gateway and service provider supports SOAP and Web services security.
一旦执行了服务实现的业务逻辑并且获得了一个响应，同样的Web服务安全性（WS-Security）操作就在 Web 服务的响应消息上进行。
Once the business logic of the service implementation has executed and a response is available, the same WS-Security operations take place for the web services response message.
对于普通节点之间的安全认证，通过服务提供者提供额外的安全认证服务实现。
Through the process, service requesters and providers can be authenticated and services can be used credibly and securely.
