Community Single Sign-On (CSSO)

The shibboleth based EDIT CSSO has been discontinued and is no longer available.

The aim of EDIT's Community Single Sign-On (CSSO) security infrastructure is integrating various EDIT service providers into the platform such as registered users of the EDIT community may access these services using a single EDIT identity only. Simultaneously, the CSSO security infrastructure respects the requirements of many biodiverity service providers to remain the sovereigns of their resources and services offered. That means, service providers may define and enforce individual access control policies in order to protect their resources, i.e. enable or prevent certain users or groups from accessing specific services.

Technologically, EDIT's CSSO Security Infrastructure bases on the OASIS Security Assertion Markup Language (SAML)": standard family. The main benefits of SAML include a secure attribute exchange framework, several open source implementations, privacy-preserving access to individually protected online resources and a federation concept. In particular, this federation concept perfectly matches the requirements regarding the creation of a single sign-on platform for more or less closed communities like e.g. taxonomic experts within EDIT. Beside others, the EDIT federation currently consists of about 2000 taxonomic experts registered in an SAML Identity Provider (IdP) and several SAML Service Providers (SP) instances like e.g. "EDITExpertNet

While, the vision is to extend the CSSO concept from EDIT to the whole biodiversity community someday, this document will present an outline to any available information regarding the existing CSSO release.
