As you might have guessed, named pipes transport the messages. Named pipes are optimized for on-machine, cross-process communications. Because it s much more difficult to sniff traffic crossing a named pipe connection than through an HTTP connection, named pipes don t have the same built-in consideration for security that HTTP does, for example. Yet named pipes as a WCF binding type support transport security. In fact, the provided implementation is basically the same as the security in TCP binding. The main difference between named pipes and TCP is that TCP implements a few additional features. The following configuration element demonstrates the differences:

Notice that there is no specification for the client credentials within the transport element. With named pipes, the only type of credential allowed is Windows. That is the only difference, however. Named pipes provide the same choices for protection level. Table 7-3 displays a list of choices for the protectionLevel. You can configure the netNamedPipeBinding through code, also, as illustrated in the following code sample:

The msmqIntegrationBinding binding is optimized for creating WCF clients and services that interoperate with non-WCF MSMQ endpoints. This binding supports transport security with Windows security used for authentication (including AD DS as the certificate authority). These requirements mean that using transport security with this binding is valid only if both client and service are in the same domain. With message signing, MSMQ provides the ability to attach an arbitrary certificate to the message (not just one that is registered with AD DS). The certificate, in this instance, is not used for authentication but to ensure that the message was signed using the certificate. The following code sample shows an example:

You might have noticed that the transport element has become much more complicated than the previous bindings or, at least, more options are available to configure. The attributes can be divided into two categories. The msmqAuthenticationMode attribute controls how the user who is requesting that a message be sent is to be authenticated. The other three attributes (msmqEncryptionAlgorithm, msmqProtectionLevel, and msmqSecureHashAlgorithm) deal with securing the message itself. For the msmqAuthenticationMode attribute, there are three possible values. If this attribute is set to None, no authentication is performed as part of the transport security. By setting the attribute to WindowsDomain, you are telling WCF to use AD DS to retrieve the security identifier (SID) for the sender. This SID will be included in the message and will be used to authenticate the sender. If the attribute is set to Certificate, the message will use a certificate taken from the certificate store to enable authentication. This means that AD DS integration is not required (by MSMQ, that is). In some instances, this is the only value that will enable transport security. For example, if MSMQ is installed in workgroup mode, it is not part of AD DS. In that situation, Windows
Lesson 1: Transport-Level Security
Domain authentication would fail and Certificate authentication is the only way to implement transport security across an MSMQ-based binding. When a message is sent using Certificate authentication, no Windows SID is associated with the message. As a result, the permissions on the target queue must allow anonymous users to post a message to the queue. This might seem a little odd, especially given that a certificate credential has been provided with the message. However, when WCF receives a message, the incoming message is checked to see whether it was signed with a certificate, and there is no guaranteed connection between the certificate that was used to sign the message and the identity of the user who sent the message to the queue. Again, there might be a connection, but the relationship can t be guaranteed. As a result, WCF won t use the signing certificate to perform authentication of the requester. With no authentication mechanism available, the request must be made anonymously to be posted. The msmqProtectionLevel attribute has the same values as the protectionLevel attribute in some of the earlier bindings. Table 7-3 displays a detailed list of the values and their meanings. The one caveat is that to encrypt a message, WCF must have access to AD DS because the key used to encrypt the message is the public key from the receiving queue, and that information (the key) will be retrieved from AD DS as part of the encryption process. If the message is sent in an environment in which no AD DS is available, there would be no way to encrypt the message so that only the recipient could decrypt it. This also implies that encrypting the message is not possible unless MSMQ has been installed using AD DS integration (that is, not in workgroup mode). The msmqEncryptionAlgorithm attribute determines the algorithm used to encrypt the message. Valid values for the attribute are RC4Stream and AES. Both algorithms are available natively within .NET. The AES algorithm is valid only if the sender has MSMQ 4.0 installed and the target queue is hosted on MSMQ 4.0. The msmqSecureHashAlgorithm attribute specifies how the digest of any signatures will be hashed. As with the msmqEncryptionAlgorithm, there is only a short list of possible choices: MD5, SHA1, SHA256, and SHA512. You can configure the MsmqIntegrationBinding also through code, as illustrated in the following code sample:
' VB Dim binding As MsmqIntegrationBinding = New MsmqIntegrationBinding() binding.Name = "TransportBinding" binding.Security.Mode = MsmqIntegrationSecurityMode.Transport binding.Security.Transport.MsmqAuthenticationMode = _ MsmqAuthenticationMode.WindowsDomain // C# MsmqIntegrationBinding binding = new MsmqIntegrationBinding(); binding.Name = "TransportBinding";
