SAML


Show me everything on Financial transaction protocols and security

DEFINITION - SAML (Security Assertion Markup Language) is an Extensible Markup Language (XML) standard that allows a user to log on once for affiliated but separate Web sites. SAML is designed for business-to-business (B2B) and business-to-consumer (B2C) transactions.

SAML specifies three components: assertions, protocol, and binding. There are three assertions: authentication, attribute, and authorization. Authentication assertion validates the user's identity. Attribute assertion contains specific information about the user. And authorization assertion identifies what the user is authorized to do.

Protocol defines how SAML asks for and receives assertions. Binding defines how SAML message exchanges are mapped to Simple Object Access Protocol (SOAP) exchanges. SAML works with multiple protocols including Hypertext Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), File Transfer Protocol (FTP) and also supports SOAP, BizTalk, and Electronic Business XML (ebXML). The Organization for the Advancement of Structured Information Standards (OASIS) is the standards group for SAML.
