INCOMMON
FEDERATION: PARTICIPANT
OPERATIONAL PRACTICES
Participation in the InCommon Federation (ÒFederationÓ) enables a federation
participating organization ("Participant") to use Shibboleth identity attribute sharing technologies to manage access to on-line
resources that can be made available to the InCommon community. One goal of the Federation is to develop, over time,
community standards for such cooperating organizations to ensure that shared attribute assertions are sufficiently robust and trustworthy to manage access
to important protected resources.
As the community of trust evolves, the Federation expects that
participants eventually should be able to trust each other's identity management systems and resource
access management systems as they
trust their own.
A fundamental
expectation of Participants is that they provide authoritative and accurate
attribute assertions to other Participants, and that Participants receiving an
attribute assertion protect it and respect privacy constraints placed on it by
the Federation or the source of that information. In furtherance of this goal, InCommon
requires that each Participant make available to other Participants certain
basic information about any identity management system, including the identity
attributes that are supported, or resource access management system registered
for use within the Federation.
Two criteria for
trustworthy attribute assertions by Identity
Providers are: (1) that the identity management system fall under the
purview of the organizationÕs executive or business management, and (2) the
system for issuing end-user credentials (e.g., PKI certificates, userids/passwords, Kerberos principals, etc.) specifically
have in place appropriate risk management measures (e.g., authentication and authorization
standards, security practices, risk assessment, change management controls,
audit trails, etc.).
InCommon
expects that Service Providers, who
receive attribute assertions from another Participant, respect the other
Participant's policies, rules, and standards regarding the protection and use
of that data. Furthermore, such
information should be used only for the purposes for which it was
provided. InCommon
strongly discourages the sharing of that data with third parties, or aggregation
of it for marketing purposes without the explicit permission[1] of the identity information providing
Participant.
InCommon
requires Participants to make available to all other Participants answers to
the questions below.[2]
Additional information to help answer each question is available in the
next section of this document.
There is also a glossary at the end of this document that defines terms
shown in italics.
1.1
The InCommon
Participant Operational Practices information below is for:
1.2 Identity Management and/or Privacy information
Additional information about the
ParticipantÕs identity management practices and/or privacy policy regarding
personal information can be found on-line at the following location(s).
The
following person or office can answer questions about the ParticipantÕs identity management system or resource
access management policy or practice.
The most critical responsibility that an
Identity Provider Participant has to the Federation is to provide trustworthy
and accurate identity assertions.[3] It is important for
a Service Provider to know how your electronic
identity credentials are issued and how reliable the information associated
with a given credential (or person) is.
Records of current employees and students are extracted from our
institutional Human Resources and Student Information Systems (both are
components of SunGardHEÕs Banner) and provisioned
unique identities in UAÕs IdM. Business practices routinely discover
and flag instances of multiple (ÒduplicateÓ) records for a single individual
and mark those records as Òbad.Ó Identities based on ÒbadÓ records are removed
from our IdM.
An employeeÕs identity is inactivated upon termination; a studentÕs
identity is inactivated after three sequential terms with no course
registration.
ÒGuestsÓ may have identities
created in our IdM through sponsorship by a
recognized department. Only those
granted specific administrative role in our IdM are
technically able to add guests.
Those roles are in turn granted through designated Òsecurity
coordinatorsÓ at each institution.
Departments are annually provided the names of people they are
sponsoring and must explicitly request renewal for those identities to be
retained.
2.2 ÒMember
of CommunityÓ[4] is an assertion that might be
offered to enable access to resources made available to individuals who
participate in the primary mission of the university or organization. For example, this assertion might apply
to anyone whose affiliation is Òcurrent student, faculty, or staff.Ó
What subset of persons registered in your identity management system would you
identify as a ÒMember of CommunityÓ in Shibboleth identity assertions to other InCommon Participants?
Non-terminated employees and
students registered in the current term.
Non-terminated employees include some who do not have a current
assignment (for example, faculty on sabbatical or other leave). While some calendar days on the
University calendar are not in any term, for purposes of determining whether a
student is registered Òin the current termÓ, a date between terms designates
the change from one term to the next.
For some purposes, such as maintaining access to email and portal
accounts, we allow students to authenticate and maintain access to accounts up
to three terms after their last registration; we would consider using this
extended subset for Òmember of communityÓ for specific services or resources.
As described in 2.1, current employees (faculty and staff) and
students in our HR and Student information system of record (Banner) are automatically
provisioned identities (currently via a once/day extract, but potentially more
frequent data exports or database triggers). Employee records are entered only by the
institutionsÕ offices of human resources. Students may register in person through registrars, or
entirely online; payment is required to complete registration. Unlike employees and students,
identities of guests are typically not vetted; in addition to being designated
a sponsored person with a responsible official sponsoring department in our IdM, their username and id are prefixed with the string Òuaguest_Ó.
2.4 What technologies are used for your
electronic identity credentials (e.g., Kerberos, userID/password, PKI, ...) that are relevant to
Federation activities? If more than
one type of electronic credential is issued, how is it determined who receives
which type? If multiple
credentials are linked, how is this managed (e.g., anyone with a Kerberos
credential also can acquire a PKI credential) and recorded?
Entities in the IdM have passwords that
are stored in MIT Kerberos KDC, which is the backend credential store of the UA
Enterprise LDAP directory; we use the Duke University Kerberos plug-in for
using the external KDC. Prior to October
2008 passwords were stored in the internal LDAP database; as these
passwords are reset by users, their accounts are Òkerberized.Ó All active accounts should be kerberized by the end of CY2009.
We require connections to our
LDAP and IdM web interfaces to use encrypted
(https) sessions, so clear text passwords are not sent for LDAP authentication,
for our CAS-like web central authentication service, nor, obviously, to the
Kerberos KDC. We expect
applications using LDAP or our web authentication service to receive and send
passwords using encrypted communications only, but realistically cannot guarantee
compliance.

Architect David Bantz, Q@alaska.edu
2.6
If you support a Òsingle sign-onÓ
(SSO) or similar campus-wide system to allow a single user authentication
action to serve multiple applications, and you will make use of this to
authenticate people for InCommon Service Providers,
please describe the key security aspects of your SSO system including whether
session timeouts are enforced by the system, whether user-initiated session
termination is supported, and how use with Òpublic access sitesÓ is protected.
UAÕs central authentication service for web-based applications is
not strictly speaking an SSO service; each application requests
authentication. However, it is
possible to authenticate to the service itself and then launch multiple
subscribing services without explicitly re-authenticating. This SSO-like function will not be used for or available to InCommon Service Providers. Session time-outs are not in place. Sessions are
terminated with close of browser window(s) for that service.
2.7 Are your primary electronic identifiers for people, such
as Ònet ID,Ó eduPersonPrincipalName, or eduPersonTargetedID considered to be unique for all time to
the individual to whom they are assigned?
If not, what is your policy for re-assignment and is there a hiatus
between such reuse?
Locally assigned identifiers and
used within UAÕs IdM are intended and controlled to
be unique for all time to the individual to whom assigned. (We do have legacy identifiers in use
on some systems that have in the past been re-issued, but these are not used as
unique identifiers within UAÕs IdM.) UA assigns a name-based ÒUA UsernameÓ
and a number-like string ÒUA ID#Ó and a UID meaningful only internal to the IdM. Kerberos
principals are UAID#@ALASKA.EDU.
Sponsored accounts (guests) receive UA Username and UA ID# prefixed with
the string Òuaguest_Ó.
UA Usernames may be changed if the personÕs legal name changes,
but the old UA Username is not available for re-issue. UA ID# is intended and controlled to be
permanent (does not change regardless of status of the person).
2.8 How is information in your
electronic identity database acquired and updated? Are specific offices designated by your administration to
perform this function? Are
individuals allowed to update their own information on-line?
For employees and students: A
personÕs legal name, preferred first name, student registration data (campus
and program of each course, declared major and minor, credit hours), employment
information (home department, employee type), assigned UA Username and UA ID#
originate in and are updated from Banner only. These data in Banner may generally be
edited only by UAÕs HR offices (for employees) and RegistrarÕs offices (for
students. Some employee
data may be updated by the employeeÕs departmental administration. Students may register and change registration
on line.
Information about email accounts
assigned to an individual may be entered and updated by other individuals with
the IdM role of email administrator. Email administrators are responsible
for entering assigned email account information (address, authentication
method, protocols supported) and may edit the mailRoutingAddress
and advertised email address (each of which may have a different value).
Data not actively maintained in Banner HR or Banner SIS may be
entered and updated by individual users; this includes: employee working title,
secretary, office location, phone, advertised email address, URL, USPS mailing
address. In addition, individuals
may edit their mailRoutingAddress, assign themselves
vanity email addresses routed to their mailRoutingAddress,
and edit the email addresses advertised in the public directory.
2.9 What information in this database is
considered Òpublic informationÓ and would be provided to any interested party?
For students who elect
confidentiality of their records under FERPA: no data is public information;
not even the existence of the record is public or would be confirmed even if an
inquirer provides a identifier.
For other students: UA has
designated Òdirectory informationÓ that includes name, campus, major or program
of study, email address; this is the data that would be provided and is
available via our public electronic directory.
For employees: name, home and other departments or units with
which affiliated, working title, email, campus (office) location(s), phone(s),
mailing address, administrative contact (ÒsecretaryÓ attribute). Note that not all
this data is automatically populated so may not be present for some employees.
2.10 Please identify typical classes of
applications for which your electronic identity credentials are used within
your own organization.
web applications, including MyUA portal
Blackboard Course
Management System
Online Directory
(ÒphonebookÓ) also used to publish printed directories
Wireless network access
(currently not used, but has been and may again)
Document imaging and
management system
Help Desk (Service
Center) incident tracking
Student Health Service
application
Google Apps for Education
Attributes are the information data elements in an attribute assertion you
might make to another Federation participant concerning the identity of a
person in your identity management system.
2.12 Would you consider your attribute
assertions to be reliable enough to:
[X] control access to on-line
information databases licensed to your organization?
[X] be used to purchase goods or
services for your organization?
[X] enable
access to personal information such as student loan status?
Federation Participants must
respect the legal and organizational privacy constraints on attribute
information provided by other Participants and use it only for its intended
purposes.
2.13 What restrictions do you place on the
use of attribute information that you might provide to other Federation
participants?
Non-public information could be
released only under explicit agreements reviewed and approved by appropriate UA
executive authority; such agreements would spell out restrictions on use. Member ofÉ, current student, current
employee, and departmental affiliations are public information. However, we could not release the name
or other uniquely identifying attributes of students electing to retain
complete confidentiality of their educational record under FERPA.
2.14 What policies govern the use of attribute information that you might
release to other Federation participants?
For example, is some information subject to FERPA or HIPAA restrictions?
Non-public information could be released
only under explicit agreements reviewed and approved by appropriate UA
executive authority; such agreements would spell out restrictions on use. Member ofÉ, current student, current employee, and departmental affiliations are
public information. However, we
could not release the name or other uniquely identifying attributes of students
electing to retain complete confidentiality of their educational record under
FERPA.
Service 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 Identity Providers. Service 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.
3.1 What attribute information about an
individual do you require in order to manage access to resources you make available
to other Participants? Describe
separately for each service ProviderID that you have
registered.
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.?
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?
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?
3.5 If personally identifiable
information is compromised, what actions do you take to notify potentially
affected individuals?
4.1 Technical Standards, Versions and Interoperability
Identify the version of Internet2 Shibboleth
code release that you are using or, if not using the standard Shibboleth code,
what version(s) of the SAML and SOAP and any other
relevant standards you have implemented for this purpose.
Shibboleth
2.x; Shibboleth 2.0 IdP is running currently
Are there any other considerations or
information that you wish to make known to other Federation participants with
whom you might interoperate? For example, are there concerns about the use of
clear text passwords or responsibilities in case of a security breach involving
identity information you may have provided?
No.
access
management system |
The
collection of systems and or services associated with specific on-line
resources and/or services that together derive the decision about whether to
allow a given individual to gain access to those resources or make use of
those services. |
assertion |
The
identity information provided by an
Identity Provider to a Service Provider. |
attribute |
A
single piece of information associated with an electronic identity database record. Some attributes
are general; others are personal.
Some subset of all attributes
defines a unique individual. |
authentication |
The
process by which a person verifies or confirms their association with an electronic identifier. For example, entering a password that
is associated with an UserID
or account name is assumed to verify that the user is the person to whom the UserID was issued. |
authorization |
The
process of determining whether a specific person should be allowed to gain
access to an application or function, or to make use of a resource. The resource manager then makes the
access control decision, which also may take into account other factors such
as time of day, location of the user, and/or load on the resource system. |
electronic
identifier |
A
string of characters or structured data that may be used to reference an electronic identity. Examples include an email address, a
user account name, a Kerberos principal name, a UC or campus NetID, an
employee or student ID, or a PKI certificate. |
electronic
identity |
A
set of information that is maintained about an individual, typically in
campus electronic identity databases. May include roles and privileges as
well as personal information.
The information must be authoritative to the applications for which it
will be used. |
electronic
identity credential |
An
electronic identifier and
corresponding personal secret
associated with an electronic identity. An electronic identity credential typically is issued to the person
who is the subject of the information to enable that person to gain access to
applications or other resources that need to control such access. |
electronic identity database |
A structured collection of information pertaining to a given
individual. Sometimes referred
to as an "enterprise directory." Typically includes name, address, email address,
affiliation, and electronic
identifier(s). Many
technologies can be used to create an identity
database, for example LDAP or a set of linked relational databases. |
identity |
Identity is the set of information
associated with a specific physical person or other entity. Typically an Identity Provider will
be authoritative for only a subset of a personÕs identity information.
What identity attributes might be relevant in any
situation depend on the context in which it is being questioned. |
identity management system |
A set of standards, procedures and technologies that provide
electronic credentials to individuals and maintain authoritative information
about the holders of those credentials. |
Identity
Provider |
A campus or other organization that manages and operates an identity management system and offers
information about members of its community to other InCommon
participants. |
NetID |
An electronic identifier
created specifically for use with on-line applications. It is often an
integer and typically has no other meaning. |
personal secret (also verification token) |
Used in the context of this document, is synonymous with
password, pass phrase or PIN. It
enables the holder of an electronic
identifier to confirm that s/he is the person to whom the identifier was
issued. |
Service Provider |
A campus or other organization that makes on-line
resources available to users based in part on information about them that it
receives from other InCommon participants. |
[1] Such permission already might be implied by existing contractual agreements.
[2] Your responses to these questions should be posted in a readily accessible place on your web site, and the URL submitted to InCommon. If not posted, you should post contact information for an office that can discuss it privately with other InCommon Participants as needed. If any of the information changes, you must update your on-line statement as soon as possible.

[4] "Member" is one possible value for eduPersonAffiliation as defined in the eduPerson schema. It is intended to include faculty, staff, student, and other persons with a basic set of privileges that go with membership in the university community (e.g., library privileges). ÒMember of CommunityÓ could be derived from other values in eduPersonAffiliation or assigned explicitly as ÒMemberÓ in the electronic identity database. See http://www.educause.edu/eduperson/
