Identity, Access Management and Single Sign-On
The following sections detail the recommendations for implementation of an identity and access management
solution offering single sign-on capabilities into the Global Organization enterprise.
Overview
Identity and access management is defined as a shared platform and consistent processes for managing
information about users: who they are, how they are authenticated and what they can access.
Enterprise Identity and Access Management (IAM) is defined as a set of processes and technologies to effectively
and consistently manage modest numbers of users and entitlements across multiple systems. In this definition,
there are typically significantly fewer than a million users, but users typically have access to multiple systems and
applications.
Enterprise identity and access management scenarios should include:
 Password synchronization and self-service password reset.
 User provisioning, including identity synchronization, auto-provisioning and automatic access
deactivation, self-service security requests, approvals workflow and consolidated reporting.
 Enterprise single sign-on – automatically filling login prompts on client applications.
 Web single sign-on – consolidating authentication and authorization processes across multiple web
applications.
The figure below illustrates the basic concepts of identity and access management:
Figure 1 Identity and Access Management concepts
Current Global Organization EnterpriseEnvironment
The following sections detail the current Global Organization system and application environment.
Active Directory
The following sections detail information concerning Global Organization’s Active Directory forest implementation.
Multiple Active Directory Forests
Global Organization has multiple Active Directory forests deployed to support operations. In order to meet
compliance with Federal and Global Organization customer security requirements, Global Organization has
deployed Active Directory forests which have no trust relationships with other Active Directory forests. The lack of
trust relationship prevents users in one forest from using their credentials to access resources in another forest.

10. Global Organization
Enterprise Identity and Access Management Design Criteria
Documentation Sample 10
ADFS/SAML
Global Organization has implemented Active Directory Federation Services (ADFS) and Security Access Markup
Language (SAML) version 2 to provide users with Single Sign-On access to systems and applications located
across organizational boundaries. It uses a claims-based access control authorization model to maintain
application security and implement federated identity. Although SAML 2.0 is the industry standard, not all
application vendors have developed support models to allow utilization; and, legacy applications within the Global
Organization environment may not be capable of support.
Kerberos/NTLM
Systems and applications which use the user’s Active Directory credentials to grant access to resources use
either the Kerberos or NT LAN Manager (NTLM) protocols. NTLM does not support any recent cryptographic
methods, such as AES or SHA-256; and, Kerberos has replaced NTLM as the default authentication protocol in
Active Directory. 1
Public Key Infrastructure/Certificate Authority
Global Organization does not have an Enterprise Certificate Authority implemented. Global Organization has
implemented a limited Active Directory Certificate Authority, which requires certificate requester explicitly supply all
identifying information about themselves and the type of certificate that is wanted in the certificate request. The
administrator has to explicitly distribute the stand-alone CA's certificate to the domain user's trusted root store or
users must perform that task themselves.
Identity Management
The following sections detail how identities are managed in the current Global Organization system and
application environment.
NetIQ Directoryand Resource Administrator
Account properties and values for Active Directory objects (e.g. user’s accounts, computer objects, printers, etc.)
are managed with the NetIQ Directory and Resource Administrator (DRA). The NetIQ DRA solution has been
deployed throughout the Global Organization environment globally. 2
Open SourceSoftware
Identity creation on Open Source Software is on an ad hoc basis by the system administrators for those systems.
A project has been initiated to implement a management solution that will include implementing the utilization
Active Directory credentials and authentication to grant access to Open Source Software systems and
applications.

Global Organization applications include; but are not limited to the following3:
 SAP
 ADP
 SharePoint
 Service Now
 Success Factors
 WebEx
 Global Organization Business Connect
 Gentrify
 Citrix
Access Management
The following sections detail how users are granted access to resources in the current Global Organization
system and application environment.
Access via Active DirectorySecurity Groups
Applications and systems using Active Directory credentials and authentication (Kerberos or NTLM) should use
membership in Active Directory security groups to grant access to resources. Membership in security groups is
controlled by the NetIQ DRA solution.
MicrosoftExchange Server
Global Organization has Microsoft Exchange Server deployed in the environment to meet client requirements for
messaging systems which Google mail does not meet. Mail-enabled Active Directory user objects and
membership in Active Directory security groups is used to control access to Exchange server mailboxes.
NetIQ Aegis
NetIQ Aegis is a process automation tool which shall be used for user account provisioning. NetIQ Aegis
integrates tightly with the NetIQ Directory and Resource Administrator solution currently deployed in the Global
Organization production environment.
Google Mail
Users access Google Mail by providing their Active Directory credentials (username and password) into a HTML
form.
3Not all applications are supported by the GlobalOrganizationCallCenter; thus this listshould notbeconsidered allinclusiveofall applications deployed
in the GlobalOrganizationproduction environment.

Open SourceSoftware
Access management on Open Source Software is on an ad hoc basis by the system administrators for those
systems. A project has been initiated to implement a management solution that will include implementing the
utilization Active Directory credentials and authentication to grant access to Open Source Software systems and
applications.
Wireless Access
Access to the wireless access networks is granted via WPA2-AES with PEAP using RADIUS (as an unknown
user) to authenticate the user against Active Directory.
GlobalOrganization Applications
Global Organization applications include; but are not limited to the following:
 SAP
 ADP
 SharePoint
 Service Now
 Success Factors
 WebEx
 Global Organization Business Connect
 Gentrify
 Citrix
Requirements
The following sections details the requirements for implementation of an identity and access management
solution offering single sign-on capabilities into the Global Organization enterprise.
The implemented solution must meet the following requirements:
 Stake holders in technical and business areas must be identified.
 Executive-level sponsorship must be secured to broker agreements between stake holders.
 Solution must support multiple Active Directory forests with no trust relationships.
 Solution must support NTLM/Kerberos/SAML/Certificate/Web Cookie authentication protocols.
 Solution must support potential multiple authoritative identity sources for enterprise IDs (partners, clients,
external service providers, etc.).
 Solution must offer auditing and reporting of enterprise identity access and utilization.
 Solution flexible enough to provide SSO service to future applications.
 Solution must support multiple-factor authentication.
 Solution must support application to application authentication.
 Solution must offer redundancy to avoid single point of failure during maintenance windows.

13. Global Organization
Enterprise Identity and Access Management Design Criteria
Documentation Sample 13
 Solution must allow segregation of administrative staff to meet compliance with Federal regulatory
requirements, such as DOD, ITAR, etc. for business units doing work with the Federal government.
 Solution will need to offer seamless, multiple method password changes.
 Solution must support the IEEE standard 802.1x for integration with Cisco ISE.
 Solution must support the Tangoe MDM solution.
 Solution must provide an access management component.
 Solution must employ full-time resources from the engineering, application and operations technical
teams from the start of implementation.
The figure below illustrates the required components of an enterprise identity and access management solution:
Figure 2 Identity and Access Management Required Components
Solution Models
The following sections detail proposed solution models and a recommended implementation methodology.
Third-Party Solution
A third-party software solution should offer a centralized technical identity data from multiple sources transformed
into rich, business-relevant information allowing enforcement of role-based access across the diverse enterprise
applications within Global Organization. An integrated solution would prioritize compliance and security efforts by
assess the risk of each person, application and system resource, and allow detection and prevention of policy
violations. By centralizing identity management into a central identity warehouse repository, governance would be
achieved by enabling provisioning of user accounts and orchestration of changes to user access across multiple
systems. Role modeling and risk analysis would locate and identify risks associated with inappropriate or
excessive access privileges. Administrative overhead associated with compliance reporting would be reduced by
enterprise governance, access request, and provisioning policies within the governance platform.

14. Global Organization
Enterprise Identity and Access Management Design Criteria
Documentation Sample 14
User frustration and administrative overhead would also be reduced by a decrease in the number of identities and
passwords required to access resources within the Global Organization environment; and, the associated amount
of time required by the diverse number of technical teams responsible for troubleshooting access management of
those resources.
CurrentADFS/SAML Implementation
Global Organization has implemented Active Directory Federation Services (ADFS) and Security Access Markup
Language (SAML) version 2 to provide users with Single Sign-On access to systems and applications located
across organizational boundaries.
However, not all Active Directory forests in the Global Organization environment have ADFS and SAML
implemented and additional systems and configuration would need to be implemented. A large number of legacy
systems in the environment are not SAML-capable and users would continue to be required to input credentials
into those solutions. In addition, Global Organization has encountered vendors with SAML solutions which only
function when all users are contained within a single domain.
Extensive modification of the current ADFS and SAML infrastructure could be required to implement the existing
solution into all Global Organization Active Directory forests and domains.
Recommended ImplementationMethodology
It is recommended that a multi-phased approach be used for the project implementation. Each application
deployed into the Global Organization production environment should have the method of identity and access and
security controls documented; and, then be tested on a case-by-case basis. It is required that all new applications
and systems to be introduced into the environment be compliant with the selected identity and access
management solution.
