Following are foremost functions of SAML:

Seamless integration.
Exchange of records amongst distinct security domains.
Back workplace Transaction.

Question 12. What Is The Difference Between Openid And Saml?

Answer :

Following are distinction between OpenId and SAML:

SAML2 supports single signal-out however OpenID does not aid unmarried sing out.
SAML2 has one-of-a-kind bindings while the most effective binding OpenID has is HTTP.
SAML2 can be Service Provider (SP) OR Identity Provider (IDP) initiated. But OpenID constantly SP initiated.
SAML 2 is based totally on XML at the same time as OpenID isn't.

Question 13. Where Is Saml Being Standardized?

Answer :

SAML is being evolved under the auspices of OASIS, the Organization for the Advancement of Structured Information Standards. OASIS has long been a home for improvement of XML languages and protocols. OASIS hosts numerous other efforts to standardize safety-associated statistics, consisting of XACML. Many participants of the SAML Technical Committee additionally take part in associated standards paintings in different venues, along with UDDI, W3C, IETF, and the committee has liaison relationships with many of these efforts.

Question 14. When Will Saml Be Done?

Answer :

SAML 1.Zero is on the Committee Working Draft level and the SAML Technical Committee is actively soliciting feedback. The SAML Technical Committee expects to proceed to a "Last Call" for comments with a revised set of Candidate Committee Specifications on 1 February 2002, and to publish a hard and fast of Committee Specifications (a Proposed OASIS Standard) on 1 March 2002.The goal is to reap a fine end result from a vote of OASIS individuals at some point of the following three months and be published as an OASIS Standard. The OASIS process is described here.

The current TC individuals are listed here. A tremendous majority of the voting individuals of the TC are affiliated with organizations that currently sell get right of entry to control and PKI products and services.

Question 16. What Are The Major Goals Of Saml 1.Zero?

Answer :

The major purposeful desires of SAML 1.0 are as follows:

Enabling single signal-on for web users.
Exchanging authentication and authorization information in a diffusion of kinds of allotted transaction.
The SAML design displays the following priorities (in no specific order):

Provide simple capabilities to permit modern get entry to management products to interoperate.
Provide sufficient capability to maximise the probabilities of sizeable adoption with out requiring large proprietary extensions in most instances.
Produce a specification at an early enough date that organizations will no longer search for alternative answers.
Provide simple assist for emerging packages, together with SOAP-enabled e-commerce.
Identify clean mechanisms for extension, both for closed environments and for future variations of SAML.
Question 17. What Are The Major Issues That Were Postponed To Future Versions Of Saml?

Answer :

Some big functions that have been explicitly deferred had been:

Proxy login (skip-via authentication)
Dynamic consultation control
Interoperability with .Net
Service region and negotiation
Some overall performance optimizations and small features have additionally been deferred. Profiles had been described for two environments up to now, web browsing and SOAP, but extra profile contributions are being solicited.

Question 18. What Will Be The Benefit Of Having All The Major Security Vendors Implement Saml?

Answer :

Interoperability. Standardizing the interfaces among systems lets in for faster, cheaper, and more reliable integration. SAML 1.0 receives part of the way towards this intention, and destiny addition of capabilities will hold the fashion. Also, the future addition of bindings and profiles will open up these advantages to more and specific kinds of get right of entry to control.

Question 19. What Is The Connection Between Acts Of Authentication And Saml Authentication Assertions?

Answer :

Any entity which can authenticate some other entity (verify its identification) can probably act as an authentication authority and issue a SAML authentication assertion. It is as much as depending parties, for instance a PDP, to determine what authentication authorities it chooses to consider.

The manner of making sure that the entity creating a request and the entity cited by an declaration are one and the equal is dependent on the surroundings and protocols being used. The preferred mechanism furnished is the Subject Confirmation detail, which is meant to hold records appropriate to the surroundings. Possible mechanisms consist of an artifact encoded in a URL, a Kerberos service ticket, or a public key associated with signature on a record. SAML profiles will specify the details for unique conditions.

It is expected that others besides the SAML Technical Committee will define other schemes appropriate for other environments. They would possibly or may not publish these as profiles, however doing so guarantees greater interoperability.

Question 20. How Does Saml Protect Against "guy-in-the-middle" And "replay" Security Attacks In General?

Answer :

SAML does not virtually do something "in fashionable". Profiles are predicted to save you or reduce MITM assaults as plenty as possible given the constraints of the surroundings in query. The Security and Privacy Considerations record discusses what must be considered.

Question 21. How Is Trust Established Between A Client And A Saml Authority?

Answer :

SAML is a completely preferred framework which will be used in a huge kind of environments. It is as much as relying parties to decide what affirming events they trust for what functions.

Trust relationships must be set up out of band. (Also, a certain quantity of configuration facts, as an example community addresses, will have to be exchanged out of band.)

Question 22. Will Saml Pdps Need To Be Configured To Understand Only Selected Authentication Decision Queries?

Answer :

Any PDP can have rules masking a finite range of resources. If it's far asked approximately a useful resource for which it has no guidelines, it's going to produce an indeterminate reaction. It is as much as the PEP to discover a PDP that is aware of about the sources it protects. SAML does now not provide any computerized way of doing this.

Question 23. I Don't Currently Use Soap. Do I Need To Invent My Own Protocol For Requesting And Getting Saml Assertions?

Answer :

You are allowed to apply SAML requests and responses over any protocol you like. Whether you will be able to interoperate with absolutely everyone else is every other question. The SOAP-over-HTTP protocol is intended to be very simple to put in force and need to constitute much less paintings than enforcing SAML requests and deciphering SAML responses.
