Today I spoke about web identities and about Azure data sync. In the web identities talk I spoke about the identity concept and about the open ID, SAML and OAuth standards. In the Azure data sync talk I spoke about the value of sync, the Microsoft synchronization framework (MSF) and the Azure data sync service (which is based on MSF) Tomorrow I will speak about cryptography in .Net and explore different types of encryption algorithms and signing APIs. You can find the slide deck here: Web Idenytities...
Until recently, you could only sign up for a new Windows Azure subscription using your Microsoft account (LiveID) It means that your administration account is governed by a private user account. This is a major security threat. The account credentials are simple user name and password (which could be easily stolen) No “Multi factor authentication” is possible No policy and management is enforced on the administration identity All this is changing now with Windows Azure Active Directory ( WAAD ) Now...
In the last two posts we showed how to use the Azure ServiceBus service bus REST API to send a message to a topic. In this post we will see how to listen on a topic and receive a message. There are two options: 1. Receive a message and delete it from the topic. Receive and Delete public static T ReceiveAndDeleteMessage<T>( string serviceNamespace, string topicName, string subscriptionName, string token) where T : class { var address = string .Format( "https://{0}.{1}/{2}/subscriptions...
In Claim based applications we use token to provide the application (Relying party) with details (a collection of claims) about the the authenticated identity. In ASP.net web sites and WCF SOAP services SAML tokens are used as a container for the claims. SAML is a standard that describe how token and claims are constructed and how they are cryptographically protected using digital signature and encryption. SAML tokens are powerful yet they are large. The size of the token is not a real issue in ASP...
I wrote a lot about claim based Identity and access control. One of the big challenges in claim based access control is the creation of the STS. Fortunately the Azure platform has an offering in this domain – ACS AppFabric ACS Access Control Service implements a full STS in the cloud. It is simple yet powerful. The team created great videos explaining ACS and their integration with WIF. Watch and start using ACS. Manu
Claim based identity is the future of identity management. It is simple, powerful and extensible but the most important reason to use it is the fact that it delegates identity management out of the application. WIF is Microsoft's infrastructure for using Claim Based Identity. (Similar to what is WCF for networking) Recently an excellent Training Kit was released about WIF and the integration of WIF with AppFabric Azure ACS. I strongly recommend to download read and learn.
