Which among the following protocols has its roots in SOAP and WS-Specifications? SAML 2.0 OpenID Connect Oauth 2.0

Answer 1

Answer:

SAML 2.0 has its roots in SOAP and WS-Specifications.

Explanation:

• The standard used between two security domains for the exchange of authentication and authorization of data, is called as Security Assertion Markup Language 2.0 (SAML 2.0).

• A messaging protocol which allows the exchange of information (structured) and along with web services (WS) implementation in computer networks is called as, Simple Object Access Protocol (SOAP). It relies on the exchange of information in XML format, as its message format and uses HTTP to transmit the messages.  

• Since it uses the XML message format, it allows the communication between computers having heterogeneous operating system (like Linux and Windows).  

• If we now look into the working of SAML 2.0 standards, it is a method of authentication and authorization which relies heavily on the user’s identity, which has been already provided by the user. The user login information is collected in the Active Directory (AD) domain or in the Intranet. This provided information is passed on in the form of XML documents (digitally Signed).  

• Since, the base of the SAML 2.0 standard is on the exchange of XML messages and hence it is connected with SOAP and Web Services (WS).
