To register UABgrid as a resource provider for InCommon we need define the UABgrid operational practices by addressing the "Resource Provider Information" questions from section 3 of the INCOMMON FEDERATION: PARTICIPANT OPERATIONAL PRACTICES.
The questions from section 3 and proposed answers are listed below. We will likely also want to our final document to be more of an operating practices document than a list of questions and responses.
Resource Provider Information
Resource Providers are trusted to ask for only the information necessary to make an appropriate access control decision, and to not misuse information provided to them by Credential Providers. Resource Providers must describe the basis on which access to resources is managed and their practices with respect to attribute information they receive from other Participants.
UABgrid is a collaboration environment for use by UAB community members and their designated collaborators from UAB and from other campuses to organize around shared academic interests. UABgrid is a participant directed and controlled collaboration environment that will provide access to web and grid applications. Basic access will be broadly available with additional privileges granted to specific community members based on the information provided by credential providers and peers within the community.
UABgrid's planned resource provider id will be:
3.1 What attribute information about an individual do you require in order to manage access to resources you might make available to other Participants? Describe separately for each resource ProviderID that you have registered.
The only attribute required for basic access to UABgrid resources will be eduPersonPrincipleName (ePPN). This attribute is intended to provide a unique identity for each user that reflects their identity at their Identity Provider. An identity provider may supply a targeted id in addition to or in lieu of ePPN.
An identity provider may supply an email attribute along with the ePPN or targeted id. If supplied, this address should be considered a working email address. This attribute will be used to pre-populate application forms as a convenience to the end user. However, a user will be allowed to override the supplied email address and supplied an alternative working email address, verified during registration.
Please note: UABgrid will not consider the ePPN, targeted id or email address to constitute personally identifiable information. Users and identity providers concerned with privacy at the user-account level are asked to supply opaque identifiers (such as targeted id) whose mapping to personally identified information is maintained by the identity provider at the identity provider.
While this information will be sufficient for basic participation in UABgrid, access to specific resources may require additional information either asserted by the user's identity provider or by authorized peers on UABgrid. An example of these attributes may include the userss common name and affiliation as asserted by the identity provider in order to access a computational resource. Requests for these attributes will be identified and determined by resource providers on UABgrid. Users should have the ability to control the release of these additional attributes, with the understanding that denying their release may restrict their levels of privilege on UABgrid.
When requested, every effort will be made to make these additional attributes available only to the applications that require them. For example, if a grid compute resource provider requires the common name and phone number of a user, only that application will receive this additional information.
How Attributes are Used
3.2 What use do you make of attribute information that you receive in addition to basic access control decisions? For example, do you aggregate session access records or records of specific information accessed based on attribute information, or make attribute information available to partner organizations, etc.?
The ePPN will be used to identify an individual user within UABgrid both to web applications and grid resources. This will essentially by their "user identity" within the system.
The email address will enable the user to participate in provided email- based discussions related to the groups with which they participate. The email address will also be used to communicate system-wide announcements to the user and may be used by application providers to communicate with the user. Essentially, the email address considered a communication end point for the user of the UABgrid system environment.
Additional attributes that may be required for authorizations beyond basic access will be used to help identify the individual to resource providers so that authorization requests can be reviewed.
Personally Identifying Attributes Access Controls
3.3 What human and technical controls are in place on access to and use of attribute information that might refer to only one specific person, i.e. personally identifiable information? For example, is this information encrypted?
Access to the databases that store personally identifiable information will be controlled via standard system security procedures. Only UABgrid operators will have access to centrally stored attributes. Attributes made available to specific resource providers will be under the control of those resource providers. User discretion is advised.
Privileged Account Access Controls
3.4 Describe the human and technical controls that are in place on the management of super-user and other privileged accounts that might have the authority to grant access to personally identifiable information?
Privileged accounts will be restricted to a limited set of experienced UABgrid operators. These operators will be familiar with standard security practices regarding the management of personal information.
User Notification in Case of Compromise
3.5 If personally identifiable information is compromised, what actions do you take to notify potentially affected individuals?
In this event UABgrid will make a reasonable effort to contact the user via email to notify them of the event. Additionally, UABgrid will alter the user's identity provider to the compromise.
Please note, UABgrid is a pilot service. Every effort will be made to protect provided information. Users are encourage to exercise discretion and evaluate requests for information based on their trust of the services provided. At the point UABgrid becomes a non-pilot service additional operating practices and procedures may come into effect which may augment or replace those described here.
