In all the examples discussed so far, we have talked about people authenticating people or people authenticating themselves to computers In a large distributed system, however, computers are also interacting with other computers The computers may have to authenticate themselves to each other because all computers cannot be trusted equally There are many protocols that can be used to allow computer-to-computer authentication, and these protocols will, in general, support three types of authentication: client authentication, server authentication, and mutual authentication Client authentication involves the server verifying the client s identity, server authentication involves the client verifying the server s identity, and mutual authentication involves the client and server verifying each other s identity When we discuss protocols, such as Secure Sockets Layer (SSL) in 15, we will discuss the different modes they use to support client, server, and mutual authentication.

To do this, you should first configure the application to use the service model and set up the App.config file accordingly. The application template has already added all the necessary references, and the svcutil tool generated an output.config file that contains the information for App.config.

By default, the name of the endpoint and the name of the binding configuration are the same. I have found that this doesn t always run properly in the prerelease bits of WCF, but changing the name of the endpoint seems to fix this. Listing 4-5 shows an example of App.config with the endpoint renamed to default. Listing 4-5. App.config for the User Interface < xml version="1.0" encoding="utf-8" > <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IBikeService"

Whether client, server, or mutual authentication is done often depends upon the nature of the application and the expected threats Many e-commerce web sites provide server authentication once a user is ready to make a purchase because they do not want the client to submit a credit card number to a spoofed or impostor web site Spoofed web sites are a significant security threat because they do not cost much to set up On the other hand, in older cell phone networks, only client authentication was required Cell phone towers (servers) would only check that a phone (client) that attempted to communicate with it was owned by an authentic customer The phones did not authenticate the cell phone towers because cell phone towers were costly to set up, and an attacker would require significant capital to spoof a cell phone tower.
