Identity and Access
Management
(IdM/AIM)
4

One (of many) IAM Definitions
Identity and Access management (IAM) is
a broad administrative function that
identifies individuals in a system, and
controls and facilitates their access to
resources within that system by
associating user rights and restrictions
with the established identity.
5

CSU Definition of IdM
California State University definition:
– An identity management infrastructure is a
collection of technology and policy that
enables networked computer systems to
determine who has access to them, what
resources the person is authorized to
access, while protecting individual privacy
and access to confidential information.
6

Analyzing the CSU Definition
• Infrastructure - software and hardware
• Collection - not just technology
• Technology and policy – policy plays a critical role
and is an essential element of the solution
• Networked computer systems - implies distributed
technology systems communicating over a network
• Access - Who am I
• Authorized - What can I do
• Protecting - limiting access and protecting
information
7

Burton Group Definition
The Burton Group defines Identity Management as:
“A set of processes, and a supporting infrastructure,
for the creation, maintenance, and use of digital
identities.”
– Integrates data sources and manages bio-demo
information about people and devices
– Establishes electronic identity of users and devices
– Issues and validates identity credentials
– Uses organizational data and management tools to
assign affiliation attributes
– …and gives permission to use services based on
those attributes

10

Core Concepts of IdM
• People and Relationships
– Identity and fabric of trust
• Creation and Management of Identities
– Governance, business process, technology
• Access to Data, Applications, and Services
– Roles, groups, privileges
11

People and Relationships
• Different categories of affiliates
– Formal (staff, employee, student) vs. Casual
(Donor, Parent, Guest, Library Walk-in)
• Multiple affiliations and transitions
– Student workers
– Emeriti
– Administrators with Faculty appointments
– Employees pursuing degrees
• Affiliation life-cycles
12

Creation and Management of
Identities
• Vetting – collection and validation of
identity information
• Proofing – aligning collected data and
matching an actual person
• Creation of a master identity record
• Issuance of credentials
– ID/password pair
– ID card
– 2nd factor token 14

Access to Data, Applications,
and Services
• Connecting people to data and services
• Authentication decisions
– Knowing who
• Authorization decisions
– Entitlements, Affiliation type, status, level of
assurance, roles and other attributes.
15

Benefits of IdM
• Centralize directory services
– One authoritative source for applications
– One stop shopping for students and employees!
• Single sign-on – reduce the number of control gates for
access to data at the same LOA
• Remote access
• Inter-institutional access
• Lifecycle issues: “from cradle to grave” and lifetime
access
• Enhance privacy of personal information
• Improve security and safeguarding of information
• Compliance with federal and state laws and regulations
16

Emerging Uses of IdM
• Building Access Controls
• Federal Government Agencies
– NIH
• National Student Loan Clearinghouse
• Workflow
17

How Does IdM Improve
Information Security and
Privacy?
18

“The best thing about the Internet is they don’t know you’re
a dog.”
Tom Toles. Buffalo News, April 4, 2000.
19

“You’re a four-year-old German Shephard-Schnauser mix,
likes to shop for rawhide chews, 213 visits to Lassie
website, chatroom conversation 8-29-99 said third Lassie
was the hottest, downloaded photos of third Lassie
10-12-99, e-mailed them to five other dogs whose identities
are…”
20

Data Security Incidents in Higher
Education
• Higher education has had a large number of non-public
information (NPI) data releases. Primarily this is
associated with our past heavy use of social security
numbers.
• Privacyrights.org lists 184 releases in first 6 months of
2008, 43 were universities.
– Higher education’s total is lower in 2008 than in 2007
and we seem to be making some progress in that our
overall percentage of releases is going down.
21

What Do We Know About
Incidents?
• Small incidents are the most frequent.
• Many incidents revolve around individuals having
access to data that had sensitive information (NPI) and
not taking adequate security procedures.
• Data management – knowing who has access to
sensitive data, and then taking appropriate measures, is
a key aspect of protecting that data.
• Large incidents often revolve ancillary business systems
that are run outside of central IT.
22

Security Threat Environment
• The security environment is changing. The
focus should be on the behavior that we
don’t understand or manage well
– Everyone wants their own application
– Those who operate these applications
frequently do not have a strong security
background
– Assignment of privilege is decentralized and
often poorly managed
23

Why Is IdM Becoming
Increasingly Important?
• Traditional forms of authentication and authorization are
no longer sufficient for the level of assurance needed by
modern internet-based applications
• Application security is becoming increasingly onerous
(multiple applications, multiple enterprises, and multiple
user roles in multiple contexts)
• New regulations dictate more stringent identity
management processes
– HIPAA (Health Information Privacy)
– FERPA (Educational Records Privacy)
– Sarbanes Oxley (Financial Disclosures)
– Gramm-Leach-Bliley Act (Financial Information Privacy)
24

IdM and Security
• Identity management is an integral component of the
organizations overall security strategy and architecture.
• In higher education, identity management and related
systems have often been developed and managed more
as a business enabler than as part of the security
strategy.
• Looking at identity management policy and legal
constraints we see how much overlap there is with
security.
25

Policy and Legal Constraints
• Ownership of Data
– Is data stewardship well-defined?
– Is it centralized or distributed?
• Access to Data
– Formally or loosely governed?
– Access authority centralized or distributed?
• Data Administration
– Centrally managed or distributed
– Compliant with federal and state law (HIPAA)?
26

IdM and Security Are
Complimentary
• Security and Identity Management
– Risk Assessment/Management
– Data Classification
– Identification, Authentication, and Authorization
– Levels of Assurance
– Compliance
– Red Flags Program
27

Key Points to Keep in Mind
• We are in the beginning stages of managing
identity.
• There won’t be a single identity provider
solution.
• The human integration component is critical and
we need to create something flexible that people
can consistently use.
• This is a rapidly evolving area because this is a
critical component in making the Internet usable.
28

Policy Frameworks to Build On
• The evolution of security processes and procedures
from ISO 27002 provides a strong foundation for risk
management and developing strong internal controls as
these pertain to security.
• While much of the ISO 27002 program is helpful to
building a strong identity management function it was
not necessarily written for this function. As the identity
management becomes a key business driver we will see
the frameworks evolve.
• We are looking at internal audit to help us bridge some
of these gaps while the policy approaches are resolved.
30

ISO 27002: Access Control
• Business requirement for access control
– Access Control Policy
• User access management
– User registration
– Privilege management
– User password management
– Review of user access rights
• User responsibilities
– Password use
– Unattended user equipment
– Clear desk and clear screen policy
31

(cont’d)
• Network access control
– Policy on use of networked services
– User authentication for external connections
– Equipment identification in networks
– Remote diagnostic and configuration port
protection
– Segregation in networks
– Network connection control
– Network routing control
32

• Operating system access control
– Secure log-on procedures
– User identification and authentication
– Password management system
– Use of system utilities
– Session time-out
– Limitation of connection time
• Application and information access control
– Information access restriction
– Sensitive system isolation

A Model Architecture for IdM:
A Framework to Build On
35

A Model Architecture
for Identity Management
• Identity management systems aggregate information
across disparate systems. Requirements include:
– High performance – these systems drive all web-
facing customer applications and customers (or
employees) won’t wait.
– High reliability – these systems often provide all
authentication and authorization services. When
down, nothing can occur.
– High security – these systems may maintain a large
number of person attributes, sometimes including
personally protected information.

37

Identifying Authoritative Data Sources
• Authoritative data feeds for the
identity management system may
come in real time or batch from
your CRM and/or ERP systems.
•Often you have special population
groups kept in systems outside of
the ERP or CRM.
•Some systems may provide
periodic, or asynchronous updates
or be polled for new information.
•For auditors, understanding what
data sources are used and the lag
time to updating the IdM system is
essential to enforcing policy.
40

Enterprise Directory Services
• This slide forms the core of an
identity management system.
• Metadirectory is usually the
system database schema that
is updated by the core data
sources.
• Physical directories, called
LDAP, provide an interface to
services.
• For auditors, understanding
how to validate that the
business rules are
implemented and followed is
essential.
41

Applications and Services
• Applications and services are the
consumers of an IDMS. Examples
include:
– Authentication - Who am I?
– Authorization services – What can I do?
– Portals are often a common application
• Services may reside locally or be
provided by off-campus providers
through Software-as-a-Service
(SaaS) or Service Oriented
Architecture (SOA) methods.
• Audit issue is how you validate
partners are meeting service
requirements and managing data
appropriately?
42

Vendor Offerings to Build On
• Microsoft Identity Lifecycle Manager
http://www.microsoft.com/windowsserver/ilm2007/default.mspx
• Oracle Middleware Suite.
http://www.oracle.com/us/products/middleware/identity-management/index.html
43

Concept and Use of Levels of
Assurance (LoA)
44

Level of Assurance in IdM
• Identity management systems have often been business
enablers for connecting customers or external business
partners.
• Questions?
– Do all account holders have access to all services
and generate the same level of risk?
– Do you have the same level of confidence that the
identity associated with an account is who they
purport to be for all your account holders?
• If you answered ‘No’ to any of the questions above, you
might look at integrating level of assurance into your IdM
strategy.
45

Level of Assurance in IdM (cont.)
• Two distinct uses:
1. For a service provider, the level of risk to the
application or organization if an incorrectly identified
user is allowed to access the application or perform
a transaction. This can happen if someone
compromises an account password.
2. For an identity provider, the risk that the person is
not who they claim to be – in this case the person
has legitimate credentials that they acquired
frauduantly
• Organizations often perform both functions and must
look at both risks.
46

• A combination of assurance that the person presenting
their credentials is who they say they are AND they are
the person presenting the credentials.
– The degree of confidence in the vetting process; and
– The degree of confidence that the person presenting the
credential is the person you issued the credential too
• Level 1 – little or no assurance
• Level 2 – some confidence
• Level 3 – high confidence
• Level 4 – very high confidence
Assurance for Identity Providers
47

U.S. Federal Government
Identity Management Initiative
http://www.idmanagement.gov/
48

Assurance for Identity Providers
(cont.)
• Assurance of Credentials as presented by the person to
whom it was issued.
– Traditional authentication focuses on password
management. Level 2 is the highest assurance a
text-based password can achieve.
– Level 3 or 4 assurance requires two-factor
authentication. The second factor must be some
token that is issued to the user. The US government
is moving to smart ID-cards under the auspices of
HSPD-12.
49

Identity Assurance Profiles
• Determined based on three general areas
– Documentation of policies and procedures and
standard operating practices
– Registering identity subjects and issuing credentials
– Strength of authentication and shared secrets
• InCommon Bronze & Silver
• NIST 800-63 Electronic Authentication
Guideline http://csrc.nist.gov/publications/nistpubs/800-63/SP800-63V1_0_2.pdf
• Some require audit
50

Assurance for Service Providers
• Service providers follow traditional risk management
approaches (e.g., NIST 800-30) to assess the risk
associated with an authentication error:
– The potential harm or impact, and
– The likelihood of such harm or impact.
• Potential categories of harm include: reputation, financial
loss, organization harm, release of sensitive information,
risk to personal safety, and criminal or civil violations.
• Ratings use values of low, moderate, or high.
51

Setting Level of Service Assurance
52

What does Level of Assurance
mean for an Institution?
• Processes to establish credentials for remote and in
person
• Ability to identify and assert individuals and their
relationship to you
• Policy around releasing information to entities outside of
the university
• Documentation of practices
– Risk Management Methodology
– Change Management
– Business Continuity Plan
• Regular Audits
53

Using Levels of Assurance to
Enhance Security
• Security is about risk mitigation.
• LOA allows you to mitigate risk in your
authentication processes.
• Identify applications needing higher security and
then identify the people using those
applications. Those individuals are the ones
which require a higher LOA.
– Examples - Faculty and staff with financial or payroll
approval, system admins and senior administrations.
54

Questions and Open Discussion
55

Concept and Use of Federated
Identity Management
57

What Do People Want?
• Institution wants to offer services to their
constituents but doesn’t want to host them.
• Vendor wants to offer a service to institutions but
doesn’t want the burden of managing user
credentials and authentication.
• User wants seamless access to services. “Single
Sign-On”.
• Security officer wants to protect University
assets, user identity information, and passwords.
58

Is There A Standard For This?
• SAML 2.0 – Security Assertion Markup
Language
– An OASIS standard managed by the OASIS
Security Services Technical Committee
– Vendor and industry acceptance
– Over 70 solutions certified by the Liberty
Alliance

Federations and Identity Management
• Federations – definition
– Dictionary.com - a federated body formed by a
number of nations, states, societies, unions, etc.,
each retaining control of its own internal affairs.
– InCommon.org - a federation is an association of
organizations that come together to exchange
information, as appropriate, about their users and
resources in order to enable collaborations and
transactions.
62

Attributes: Entitlement, Anonymous ID, Affiliation…
Metadata, certificates, common attributes & meaning,

1. User attempts to access
protected resource. Selects
home institution and is
redirected to home.
2. Authentication: single-sign-on at
home institution
3. Federation-based trust
exchange to verify partners
and locations
4. Authorization: Privacy-
preserving exchange of
agreed upon attributes
5. If attributes are acceptable to
resource policy, access is
granted!

Benefits of Federations
• For organizations, without a federation, organizations
that want to share information must enter into bilateral
agreements. These agreements are difficult to achieve
and greatly complicate the work of insuring compliance if
each has slightly different terms.
• For individuals, without a federation, individuals must
establish a relationship with each organization, often
providing duplicate information to multiple organizations.
65

Basic Requirements for
Federating
• Relationships
– Attributes, Roles, Life cycles
• Transport Mechanisms
– Standards - SAML, OpenID, InfoCard

used to assess identity providers:
– “Identity Assurance Assessment Framework”
– “InCommon Bronze and Silver Identity Assurance Profiles”
• Supporting documents
– InCommon Attribute Overview
– InCommon Attribute Summary
– Assurance Profile Assessment Checklist - This checklist should
be used in conjunction with the InCommon "Identity Assurance
Assessment Framework" and the InCommon "Bronze and Silver
Identity Assurance Profile" documents. The checklist is intended
to aid in self assessment by Identity Providers and provide
background for a final assessment by qualified IT auditors.

Ideally, individuals would each like a
single digital credential that can be
securely used to authenticate his or her
identity anytime authentication of
identity is required to secure any
transaction.
William Weems, Ph.D. UT Health Science Center at Houston: Sharing Restricted Resources Across Organizational Boundaries
82

The UT System Federation
Drivers:
• Collaboration is a key goal.
• It all started with a “statement of direction” from our leaders and a
small “starter grant” from the government
• Why our own federation?
– We know our campuses best / clear administrative boundary - could
happen quicker if we do it within the UT System.
– Ensure that no campus is left behind
– Direct control over policies and directions
– Most of our initial apps were just for our campuses
– We want to strive for providing infrastructure to meet higher LoAs
throughout UT System
83

Overview:
• Uses Internet2 technology (Open Source)
– Shibboleth
• Based upon standards and best practices
– LDAP(eduPerson), SAML, etc
• Stable, Scalable, Secure, Interoperable
• Enabling Policies Exist
– https://idm.utsystem.edu/utfed/index.html
– Based on InCommon Federation policies and
documents
• Governance Structure in Place 84

Current Applications:

• MobileCampus @ MobileCampus (.com)
– UT Austin, UT Arlington, UT Dallas, UT El Paso
• Risk Assessment Tool (ISAAC-UT)
– All UT institutions
• Time and Effort
– UT MD Anderson, UT Medical Branch
85

Lessons Learned (so far)
• Policy work is slow, but critical to establish an environment
in which trust can develop.
• It’s important to address the support needs that grow out of
a federated environment (federate the support too).
• Federated authorization is challenging and takes lots of
time and effort (AppAdmin workflow app) – training and
executive support are the keys.
86

What are the Practical Benefits
of this Approach?
• User satisfaction
– Fewer passwords to remember, increases the value of their campus credential
• Local autonomy
– Supports differing technologies, policies, and business processes
• Increased security
– No application-based loosely-coupled identities
– More granular authorization
• Lower costs
– Applications don’t have to manage separate identities for their users
• Support secure inter-institutional collaboration across the world just
as easily as across the state (well, almost)
– SAML is a mature global standard
87

Leveraging Federations:
Enhancing Information Security
and Privacy in Collaboration, SaaS,
and Cloud Computing
88

Collaboration
• With increased use of the web as user interface,
university systems are deploying administrative solutions
that support shared infrastructure for multiple institutions
• Press Release 10-023
Microsoft and NSF Enable Research in the Cloud
– “Agreement will offer free access to new computational and
collaborative services to accelerate scientific discovery for
research communities.”
– “Microsoft will provide cloud computing research projects
identified by NSF with access to Windows Azure for a three-year
period, along with a support team to help researchers quickly
integrate cloud technology into their research. “
89

Software-as-a-Service (SaaS)
• SaaS is a model of software deployment
whereby a provider licenses an application
to customers for use as a service on
demand.
• Many of the commercial service providers
joining InCommon utilize this model.
90

Some Common Higher Ed
SaaS Vendors
91

Cloud Computing
• Gartner - “a style of computing where massively
scalable IT-enabled capabilities are delivered ‘as a
service’ to external customers using Internet
technologies.”
• Wikipedia - “cloud computing is a paradigm of
computing in which dynamically scalable and often
virtualized resources are provided as a service over the
Internet. Users need not have knowledge of, expertise
in, or control over the technology infrastructure in the
"cloud" that supports them.”
92

The Challenge
• The decision to procure these services is
driven by departments instead of IT
strategy.
• Integrating these separately developed
applications into an integrated approach.
– How do you manage access?
– How do you manage provisioning?
– How do you integrate this into the web
services you provide?
• How to reduce the number of credentials
95

A Solution: Leverage Federation
• Focus on four activities:
– Develop an institutional Identity Management System
– Create a standard set of attributes for each person
(eduPerson)
– Use a federation to enable external access
– Require institutional developers and in RFPs that
service providers support SAML and InCommon
• InCommon provides an easy to use
framework for customers and service
providers that will work across higher
education.
