Wse 3.0 setup type

The following is the content of a policy file for a Web service generated using WSE 3. AnonymousForCertificateAssertion, Microsoft. XTokenProvider, Microsoft. The following is the content of a policy file for a Web service client generated using WSE 3. It is important to note, however, that when the anonymousForCertificateSecurity assertion is used the client signs and encrypts the SOAP request using EncryptedKeyToken security tokens generated using the service's X.

By using the EncryptedToken security token therefore we are able to secure both outgoing and incoming SOAP messages symmetrically even though our security credential consisted of one asymmetric key pair.

Applying the Policy to a Web service. Services3 namespace, which takes the name of the policy as a string parameter. The attribute is applied to the class of the Web Service as in the following example:. Applying the Policy to a Web service client. Once we've set a reference to our WSE-enabled Web service from our client we can then apply the Policy by calling the SetPolicy method of the service proxy class adding the name of our policy as a string parameter. The method is called from the instance of our service proxy class as in the following example:.

SetPolicy "ClientPolicy" ;. Conclusion This article looked at how security for applications that consume Web services using WSE version 3.

Furthermore, it explored notions of distribution and scalability when implementing web service security and how the WSE 3. View All. Pietros Ghebremicael Updated date Oct 04, Service clients connect to a Web service application over secure transport With WSE a SOAP message holding one or more security credentials can be routed through one or more intermediaries before reaching its destination point where it is validated, hence allowing scalability and distribution of Web service applications.

Imperative security model When it comes to specifying security requirements with WSE there are two possible options available: Defining security requirements for SOAP messages in an Xml file either by using WSE Settings tool's security settings wizard as shown in figure 3 or by manually adding policy elements, child elements and attributes to a policy file.

Figure 3. WSE Security Settings Wizard Security requirements can be defined in code, mostly when the deployment environment is known beforehand and is not likely to change, without using a policy file. To secure a Web service we use a class that derives from Microsoft. Policy and within this class we create the required turnkey security assertion class instances to which we specify the respective security credentials, and then we add to an ordered list collection exposed by the Assertions property of the Policy class as shown in the following example.

Web; using System. Services; using System. Policy assertions are a great way to hoist common code out of a Web service, or even a set of Web services. Performing security checks in the WSE pipeline before the message actually reaches the Web method is an easy way to help application developers who might otherwise forget to make those security checks on their own.

There are a lot of security-related features that you can pull up into the pipeline like this. For example, if clients use certificates to authenticate to your service, you might want to map those certificates onto real Windows user accounts so that you can make requests to back-end servers using Kerberos credentials.

Role-based access checks are another example. Any security feature you can pull up into the pipeline is a good thing, as it helps ensure a consistent security policy will be applied across all your Web methods.

What about validation of requests? Validating user input is an important step in building any secure system. If you can hoist some of that up into the pipeline, more power to you.

Aaron Skonnard did some work in this space for WSE 2. If you think you might want to build your own custom policy assertion, start with my trace assertion and work from there, but let me leave you with some hints that will help your process. Each policy assertion gets a chance to inject objects called filters into the pipeline that actually implement the policy assertion.

The filter architecture is really simple. You must derive a class from SoapFilter and override one method: ProcessMessage. The following is an example of a filter that just lets the message flow through without doing anything:. Because a policy assertion might need to behave differently in each of these four spots, the policy assertion is asked to provide filters for all four locations.

In fact, you override four methods in your policy assertion class to supply the following filters:. Note that if your policy assertion is only meant to run in the service process, you can simply throw an exception if you are asked to create a filter for a client pipeline, because the client functions will never be called for a service pipeline.

The same holds true for a client-side assertion. In my logging policy assertion, all four filters do the exact same thing: just log the current message to a named flat file.

So in my policy assertion I simply hand out an instance of the same filter class for all four methods. Additionally, I override the ReadXml method on my policy assertion so that I can configure the name of the file for each of the filters based on attributes in the XML policy file. I pass this value along to the filter I'm creating.

Things start to get interesting when you construct a policy with multiple assertions. Remember that policy determines the order of processing in the pipeline.

Imagine you write the following policy and use it for both your client and your service:. Because assertionOne is listed first, it'll be asked to inject its filters first. Then assertionTwo will inject its filters. Here's how I remember this ordering—messages flow between your program and the wire. Consider your program to be at the top of the policy, and the wire to be at the bottom. It works this way on both the client and server side, making it possible to share policy files between client and server without having to reorder them.

WSE provides three state bags that you can use for this purpose. MessageState allows state to be shared for the duration of a message as it flows through a single pipeline. And finally, SessionState, which is managed on a per-proxy basis, allows you to store state across requests. All of these state bags are available to you via properties of the SoapContext class, which itself is surfaced via the Context property of the SoapEnvelope class.

If you look back at my filter example, you'll notice that the SoapEnvelope is passed to your filter, so these state bags are easily accessible.

While developing the logging assertion, I was impressed with the logic the WSE 3. Even without documentation I was able to get a simple logging assertion up and running in about 30 minutes.

Thanks to the WSE team for a job well done! My experience shows that WSE 3. For me, the custom policy assertion architecture gives me the flexibility I need to build security plumbing that developers can then easily reuse in their applications via policy.
