1 Federations in Texas Barry Ribbeck University of Texas Health Science Center at Houston

2 Context Definitions Target: A federation member offering resource(s) Origin: A federation member requesting access to resources in exchange for asserted information Member: An entity agreeing to abide by the policies governing the federation

3 Potential Need for Federation(s) UT Information Security UT Austin Define System UTHSC-Houston Blackboard resource UTMB Center for bio-terrorism research Texas Medical Center – Houston collaborative efforts (17 physical institutions, 44 external institutions with hundreds of business partner relations per institution. Houston Higher Ed: UT-HSCH, Rice, A&M, Baylor, U of H, Texas Southern, HCC, Houston Baptist, U of St. Thomas, UT-MDACC

4 UT Infosec UT – A state agency with 17 component parts geographically dispersed across the state of Texas operating independently. Information Security (Infosec) is a cross institutional group charged with sharing information regarding security related issues and coordinating security related communications between institutions. All UT components operate under a common PKI, so a trust fabric exists Already committed to using Shibboleth as infrastructure exists to support it

5 UT Austin Define System A legacy mainframe application with extensive web front end development, used by multiple UT institutions within the state. Contains financial, student and other sensitive data. Austin is considering re-vamping their Authentication/Authorization (AA) process for this web based application as well as for the campus in general Austin no longer wants to support Identification and Authorization (I&A) for external components accessing this application.

6 UTHSCH-Houston Blackboard Houston has satellite programs dispersed around the state. Most of these programs involve faculty and students at other UT institutions. Currently, non-UTHSCH users utilizing the Houston Blackboard Course Management System resource require a guest account. Once the infrastructure is in place, it will allow courses offered at Houston to scale beyond the UT virtual boundaries. Planned deployment in Q1 2004

7 UTMB bio-terrorism facility UT Medical Branch in Galveston is building a level 4 biological research lab They are a candidate for a federal bio- terrorism facility How do we ensure security and access control to information that will be made available to collaborators inside and outside of the state?

8 Texas Medical Center 17 institutions operating independently with a 4 square mile area Largest medical center in the world Many of the faculty and providers are cross institutional affiliates. Hippa is forcing US to change the way we distribute non-mainstream health information (SMIME/Web) between institutional providers

9 Houston Higher Ed Many Institutions of higher learning Many resources (library resources) shared both locally and state wide Programs currently exist to allow students from one institution to take for credit courses at other institutions and pay for those courses locally.

10 Why does a Federation exist? To provide a venue and policy structure(s) for enterprises with common needs to access or provide digital resources securely while leveraging a common trust fabric. To provide assurance of compliance with policy of the trust fabric to relying parties. To enforce the polices of the Federation

11 Why does an Origin Join a Federeration? To provide a mechanism for its users to access external resources offered via the Federation thereby extending the utility of its internal resources in a scalable fashion To leverage the scale provided by a trust fabric and reduce the number of 1 to 1 Relying Party Agreements.

12 Why does a Target join a Federation? To provide access to resources of interest to a larger community with some level of control and accountability. To leverage the scale of a shared trust fabric and reduce the number of 1 to 1 Relying Party Agreements.

13 Why a another federation? Federations membership is based on the needs of the constituents. Target requirements and Origin requirements may not match nicely with RPA in a more generalized Federation. Will targets that require a high LOA for I&A be satisfied with an assertion of how authenticated? When Target and Origin are “close” within a federation and the applications are mission critical why outsource the federation when they are already supporting the ends. It may be easier to establish a “local” federation as policies within a community may already exist (PKI).
