SAML Version 1.0 Approved as OASIS Open Standard

Security Assertion Markup Language (SAML) Ratified as OASIS Open Standard

Authentication and Authorization Standard Enables Single Sign-On for Web Services

Boston, MA, USA. November 06, 2002

The OASIS interoperability consortium today announced that its members have approved the Security Assertion Markup Language (SAML) v1.0 as an OASIS Open Standard, a status that signifies the highest level of ratification. SAML is an XML-based framework for Web services that allows the exchange of authentication and authorization information among business partners. SAML enables Web-based security interoperability functions, such as single sign-on, across sites hosted by multiple companies.

"SAML 1.0 is an important industry standard for federating diverse security domains across Web services environments," said James Kobielus, senior analyst at Burton Group. "SAML 1.0 supports secure interchange of authentication and authorization information by leveraging the core Web services standards of Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), and Transport Layer Security (TLS). Most vendors of Web access management solutions have committed to SAML 1.0 and are currently implementing the specification in their products."

"SAML lets companies implement single sign-on solutions that allow users to visit various Web sites without being repeatedly challenged for credentials," explained Joe Pato of HP, co-chair of the OASIS Security Services Technical Committee. "In addition, SAML makes it possible to include security information in documents used in business transactions. This is particularly relevant for Web services, where security is critical."

SAML incorporates industry-standard protocols and messaging frameworks, such as XML Signature, XML Encryption, and SOAP. The specification can be easily integrated in standard environments such as HTTP and standard Web browsers. Likewise, other security environments can use SAML as an authentication and authorization layer. SAML complements Web services standards, such as SOAP, which lack inherent security features. The OASIS Web Services Security Technical Committee, for example, is profiling SAML as one of its set of security tokens.

"SAML allows vendors to interoperate for the benefit of their customers," said Jeff Hodges, Sun Microsystems, co-chair of the OASIS Security Services Technical Committee. "The standard is easily implemented by companies in existing environments, and SAML-aware security applications are already being introduced. Related security initiatives, such as Liberty Alliance's Version One Specification, are leveraging SAML in order to more quickly realize their goals."

The SAML OASIS Open Standard was developed by Baltimore Technologies, BEA Systems, Computer Associates, Entrust, Hewlett-Packard Company, Hitachi, IBM, Netegrity, Oblix, OpenNetwork, Quadrasis, RSA Security, Sun Microsystems, Verisign, and other members of the OASIS Security Services Technical Committee.

"Ratification as an OASIS Open Standard means that developers can deploy SAML with confidence," said Karl Best, director of technical operations at OASIS. "To attain this level of acceptance, SAML first completed an extensive public review, was approved by the OASIS Security Services Technical Committee, and demonstrated its readiness through multiple implementations. Finally, SAML was reviewed and approved by the OASIS membership as a whole. We congratulate and thank the members of the OASIS Security Services Technical Committee for all their outstanding efforts in advancing SAML as the newest OASIS Open Standard."

"SAML depends on the availability of authentication frameworks such as PKI digital certificates," said Terry Leahy of Wells Fargo, chair of the newly formed OASIS PKI Member Section. "We look forward to advancing PKI for end-entity authentication and for supporting persistent digital signatures conveyed through SAML assertions. Through SAML, PKI will provide a foundation for secure Web services."

Support for SAML

"SAML represents a significant step forward in helping organizations to strengthen their online business relationships by making it easier to share authentication and authorization information across corporate boundaries and security domains" commented Peter Doyle, Vice-President Marketing with Baltimore Technologies. "Baltimore SelectAccess was first-to-market with SAML support earlier this year and Baltimore remains fully committed to driving standards which can enhance online security while delivering cost savings for organizations and a better experience for their users."

"By both simplifying and strengthening online authentication and authorization, SAML will become a significant enabler of secure eBusiness in an increasingly complex and interdependent online environment," said Ron Moritz, senior vice president for eTrust security solutions at Computer Associates. "As the leader in eBusiness security software, CA will play a key role in promoting the SAML standard as we incorporate it into our entire line of our eTrust identity management and access control products."

"DataPower Technology sees open, easy to implement standards as one of the major building blocks to the foundation and success of ebusiness.
