Security Architecture

Figure 1: ESB Security Model

External Bus Security

Service connectors and client connectors connect web services to the ESB. The level of security provided by a web service depends on the binding that is used by the web service.

Adapter endpoints connect the ESB to legacy systems, enterprise resources, and line-of-business applications. The security provided by an adapter is equivalent to the security provided by the external system.

Custom applications can use the Neuron API. Connections to topics are always authenticated and authorized using Windows Security. Once connected to a topic, messages passed over the topic can be encrypted to prevent confidential information from being exposed over the network.

Internal Bus Security

Internally, all communication is facilitated by topics. Connections to topics are always authenticated and authorized using Windows Security. Once connected to a topic, messages passed over the topic can be encrypted to prevent confidential information from being exposed over the network.
