1 Development and deployment of integrated attribute based access control for collaboration

2 Collaborations and Virtual Organizations IdM is a critical dimension of collaboration, crossing many applications and user communities Virtual organizations represent critical communities of researchers sharing domain resources and applications as well as general collaboration tools. Providing a unified identity management platform for collaboration is essential in a multi-domain, multi-tool world. Lots of activities in domesticating applications to work in a federated world, moving from tool-based identity to collaboration-centric identity.

3 Collaboration Platform Integrated set of collaboration apps (wikis, listprocs, CVS, file share, calendaring, etc) Integration of at least identity and access control via group memberships Integration with domain science apps Integration of content and meta-data is harder Repackages successful approaches for a collaborative/ project/vo setting Federated identity, group management, directories, and security token services (aka credential convertors)

4 Collaboration Infrastructure (COIN) Dutch National Collaboration Infrastructure Domesticated tools -Adobe Connect; Alfresco; Foodle; Filesender; Confluence; WSO2 mashup server; OpenFire; Drupal; KnowledgeTree, Sympa and Limesurvey Domesticated services -Google Apps; MyExperiment.org; Twitter; PubMed Integration across VO, institution and third-party domains Workflow Grid integration

5 Domestication of applications The work of re-factoring applications to use the emergent identity services infrastructure Begins with federated identity and authentication, use of directories; gains a lot from group management for access control, etc Needs a fine grain set of authorization tools down the road Domesticated apps can receive IdM attributes via LDAP, SAML, X.509, SQL, Kerberos PAC, and maybe all of the above

6 Typical activities in collaboration management Add or remove people from groups Create new subgroups, identify overlapping memberships, etc. Permit or deny access control to wiki pages, calendars, computing resources, version control systems, etc Add people to mailing lists, wikis, etc Create and delete/archive users, accounts, keys Identify group membership on a given date

7 COManage Elements Dashboard Shib SP Shib IdP Data Store Grouper STS LdapPC Including provisioning Applications

8 What s in a COmanage data store Enterprise Attributes Federated Id Enrolled classes Display name Citizenship Enterprise affiliation Project/VO attributes PI groups Wiki editing permissions Instrument permissions VO certificates

9 Grouper A general purpose, extensible, open-source group management tool In production at many institutions in the US and overseas Core national infrastructure service in several countries Manages groups of things people, devices, processes Has GUI, people picker, group math, inheritance, delegation, provisioning and deprovisioning, etc. Stores values in LDAP directory Aimed at spectrum from power user to collabmin, sysadmin and enterprise IdM.

10 Security Token Service Converts the form of an existing credential or packs a set of attributes into a new credential Presents external security information to an application or service in the lingua of the app/service Conversions SAML into X.509, SAML into Kerberos, SAML to LDAP, etc. Mythical in a single comprehensive package; legion in individual instances

11 What forms does COmanage take? Usually as an assembled set of services A dashboard, directory product, Shibboleth IdP and SP, Grouper, and a set of applications provisioned on other servers On an enterprise level to serve its collaborations and VO s, within a large VO, or at a federation level to serve a national community Can also be a VM, a VM in the cloud, or a service with the applications in the cloud. Can be embedded in a science portal or gateway

12 Flows of attributes - 1 Enterprise Project comanage Relying Party Data Store Enterprise

13 Use cases it enables A student adds a class and is immediately enabled to use the VO wiki; a student drops the class and is immediately disabled from using the VO instruments A resource prohibited from use by foreign nationals is protected International privacy laws are adhered to Anonymous access is enabled but limited to those authorized to participate Security is commensurate with the risks
