For a claim based authentication to work organisations must agree on the format for exchanging claims,
rather than have each business define this format as set of specifications broadly identified as Web
services has been developed.
Any organizations that want to implement a federated identity solution can use this set of specifications.
Web services comprise a set of specifications that are used for building connected applications and
services and whose functionalities and interfaces are exposed to potential users.
Through web technologies standards such as example, simple object, access, protocol, Web Services,
description, language is to be and should be.
Has the goal of creating web applications by using Web services is to simplify interoperability for
applications across multiple deployment platforms, technologies and networks.
To enhance interoperability.
Web services are defined by a set of industry standards.
Now most web services use example to transmit data through H2 to be attached to the base.
With example, developers can create their own customized tags, thereby facilitating the definition,
transmission, validation and interpretation of data between applications and organizations.
Web services expose useful functionality to Web users through a standard protocol.
In most cases, Web services use.
So which is the communication protocol?
For example, Web services.
So is a specification that defines the SML format for messages, and it essentially describes what a
relatively simple document looks like.
Web services provide a way to describe their interface in enough detail to allow a user to built a client
application to communicate with a service.
This description is usually provided in an Excel document called a W SDL document.
In other words, a W SDL file is an SML document that describes a set of social messages and how those
messages are exchanged.
Web services are registered so that potential users can easily find them.
This is done with universal and description, discovery and integration.
Or you did.
You did.
I Directorate Andrew is an example file that describes a business and the services it offers.
Also worries about Web services, security applications.
Web services specifications include several components that are commonly known as W as their specifications.
However, the most relevant specifications for them in the first environment are the Web Services,
Security or WAC, the security specifications.
WAC.
The security includes the following specifications.
W is this security so massive security and x509 cert token profile.
WAC security describes enhancements to a sold message and that provide quality of protection through
message integrity, message confidentiality and single message authentication.
WAC Security also provides a general purpose yet extensible mechanism for associated and security tokens
with messages.
Additionally, it provides a mechanism to ensure binary security tokens.
Specifically x DOD 509 certificates and Kerberos tickets in sold messages.
Another specification of this.
WS Security is web services trust or w us distrust w ers distrust defiance extensions are built on w
are security to request and to ensure security tokens and to manage trust relationships.
Verb services for duration or W.S. does for duration.
Double use for duration.
Defines mechanisms that WAC security can use to allow attribute based identity authentication and authorization
for duration across different trust realms.
Another specification is w used for duration, passive request or profile.
This WS security extension describes how passive clients such as web browsers can acquire tokens from
a for duration server and how the client can submit tokens for duration server.
The passive requester of this profile are limited to the H2 to B or S to base protocol.
And lastly, double use for duration, active request or profile.
This WS security extension describes how active clients such as so based mobile device apps can be authenticated
and authorized and how the client can submit claims in a for durations.
Tamura also notes about security assertion markup language.
Security Assertion Markup Language or symbol is an example by standard for exchanging a claims between
an identity provider and a service or application provider.
Thermal assumes that an identity provider has authenticated a user and populated the appropriate claim
information in the security token.
Whether the identity provider authenticates the user, it passes a thermal assertion to the service
provider.
Based on this assertion, the service provider can make authentication and personalization decisions
within an obligation.
The communication between Federation servers is based on an example document that stores the x .5009
certificate for token signing and the thermal 1.1 or a thermal 2.0 token.
Next up, we'll be talking about what is a DFS.
I'll see you then.
