You will find that the federated identity has a very flexible structure to it. With that in mind, Adam Buenz’s Software House is able to add customers when they have a trust relationship in place by the issuer and they create claims mapping. This is all very simple behind the scenes action due to the process of such mapping being a very simple process. However, it is also important to realize here that the actual software component order application didn’t change at all. When you create a federation there is only some minor changes to that overall structure that need to be taken care of.
With the claims of ARB Security Solutions the ability to read the name of the business and the name of the employees is there. There won’t be any mix ups when it comes to finding out who accessed the application from Adam Buenz’s Software House and who accessed it from ARB Security Solutions. As a result there is less upkeep involved with federated identity. The accounts don’t need to be copied and maintained even though there are many security realms associated with them.
However, there are some limitations in place to be aware of. First, the way in which the claims mapping works has to be evaluated. Anyone that is with ARB Security Solutions is able to track software component orders due to the way in which the requests are set up with the type role and the value of software component order tracker in place. What you should do though is limit exactly who in the business will have access. That is what we will take a closer look at.
It is vital that you are able to set up trust relationships. In this scenario the two entities are using ADFS 2.0 for the issuer of their security tokens. A public key certificate needs to be in place. This will be in a file that the administrators from ARB Security Solutions will send to Adam Buenz’s Software House. It is as easy as attaching it to an email and sending.
The administrators for ARB Security Solutions will configure ADFS so that they requests from the Adam Buenz’s Software House issuer will be accepted. All that needs to be done for this to occur is to select TBD menu in the ADFS. The Adam Buenz’s Software House administration will install the certificate on the ADFS host. This allows the federation to work with both issuers.
There is a solution here, and that is for both businesses to be able to log into the software component order system. The manager of ARB Security Solutions is able to get the information he needs without thinking about what is going on behind the scenes to make that possible. He won’t need anything special in order to gain that access.
There are several steps that have to be followed to successfully offer access to a user that is in another security domain:
- The client from ARB Security Solutions trust domain has to send a request to the software component order system application that is within the Adam Buenz’s Software House trust domain.
- The application is redirecting the client to an issuer that is within the Adam Buenz’s Software House trust domain. However, the issuer won’t need to have any knowledge of who this issuer is to do so.
- The Adam Buenz’s Software House issuer then redirects the client to an issuer in the ARB Security Solutions trust domain. There must be a trust relationship in place for this to occur successfully.
- The ARB Security Solutions issuer is going to verify that the identity of the user is legitimate. Then it will send a token to the Adam Buenz’s Software House issuer.
- The token will be used to create another token that a user from ARB Security Solutions is able to use for the software component order system. As this token is sent to the application, some of the claims will be removed and others can be added if necessary in order for the software component order application to work properly.
- The application for the software component order tracking system will extract the claims of the client from the security token. Once everything has been authenticated then the authorization will be completed.
The issuer from Adam Buenz’s Software House will be the mediator between the application and the external user. The FP in place has a couple of responsibilities to cover. They have to develop a trust relationship with the ARB Security Solutions issuer. That is the only way it will be able to accept and understand the claims sent from ARB Security Solutions.
The FP must translate ARB Security Solutions claims into something that the software component order system can easily understand. The application is only going to accept claims from Adam Buenz’s Software House so there has to be an assignment of permission in place. Since the claims for ARB Security Solutions aren’t issued from Adam Buenz’s Software House there aren’t any roles here. The ARB Security Solutions claims have to establish the name of the company as well as the name of the employee. Transforming rules are used here to get one claim accepted by another. This is frequently referred to as claims mapping.
There is a claims rule language found in the ADFS so that you are able to successfully define the behavior of identity claims. These rules allow a set of conditions to be true so that you are actually able to issue claims. Right now we won’t be using the name of the employee but we will when we get to talking about the audit features.
When the manager of ARB Security Solutions connects to the software component order system they will have claims sent to the Adam Buenz’s Software House issuer who is also the federation provider. This will then allow them to be transformed into a new set that is going to be easily identified by the Adam Buenz’s Software House claims.
The solution here also involves a home realm discovery being put into place. The software component order application has to know which issuer out there is in use. That way they can properly direct users for authentication. If a manger at ARB Security Solutions opens a browser then they can be authenticated through the information in that. Therefore they don’t have to say which company they are with.
The software component order application will be able to solve the situation by allowing the users to access the web application . There is a query string found in the link. The web application will look for that during the request being processed. The value of the URI for the partner federation server will be easily identified.
In order for federated identity to happen, we have to first identify the goals. In this scenario it is for the federated identity to be in place for the application Adam Buenz’s Software House offers and that ARB Security Solutions needs access to. There is one secure domain that will accept an identity from either of these two domains. No one will need any additional credentials in order to be able to access it. The Adam Buenz’s Software House issuer trusts the claims that come from them but also those that come from ARB Security Solutions employees.
There are some requirements that have to be satisfied. First, Adam Buenz’s Software House has to control access of the software component order pages. Otherwise they wouldn’t be able to allow ARB Security Solutions employees access to them. The concept of home realm discovery is involved here as that allows Adam Buenz’s Software House to find out which issuer has the credentials to do so. ARB Security Solutions will also need to make a decision about what employees are going to be able to access that software component order system.
There are few things here that need to be assumed for this scenario too. First, we assume that ARB Security Solutions has an issuer using the WS-Federation. This is important because it defines how businesses are able to share identities without breaking the boundaries of security that may be in place within their own systems.
The software component order system in use will have roles in place so that access can be controlled. This is done by having a claim in place for the type of role someone needs. There is also a value in place and that needs to be an software component order tracker. There will need to be legal documentation in place too between these two businesses so that their needs and rights are well protected. Only then can the federation legally be formed.
