Identity management capabilities

Today's security infrastructure is identity driven. Secure business applications ask two key questions: who are you, and what can you access? IBM offers a complete solution for identity management across the enterprise. the identity management capabilities provided by WebSphere Application Server in conjunction with other WebSphere products and Tivoli.

For an identity management primer, refer to the identity management white paper, Help improve security and lower costs with repeatable identity management solutions. The paper describes the:

As described later, the IBM portfolio supports the following identity management capabilities.

  • Offer single sign on for your users' convenience

  • Control access to Web applications

  • Administer identities

  • Provision users

  • Federate disparate sources of identity data

  • Provide standard directory services to applications

  • Use strong authentication

  • Control and manage access to Web applications, Web services, and your Service Oriented Architecture (SOA)

  • Ensure regulatory compliance

  • Secure your business portal

  • Provide instance based access control for business rules

  • Secure work flows containing people interactions

  • Secure integration with other business applications

  • Government solutions

Products that work in conjunction with WAS to provide a full range of identity management capabilities include, but are not limited to:

Offer single sign on for your users' convenience

With WebSphere Application Server, Web users can authenticate once when accessing Web resources across multiple application servers. Choices for securely negotiating and authenticating HTTP requests for secured resources include trust association interceptor (TAI) that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO), or using Tivoli Access Manager WebSEAL or Tivoli Access Manager plug-in for Web servers as reverse proxy servers to provide access management and single sign-on (SSO) capability. See Implementing single sign-on to minimize Web user authentications for details.

Add Tivoli Access Manager for e-business to achieve Web SSO and secure session management across e-communities, to securely extend your business processes to business partners and business affiliates. You can enable a flexible SSO to Web-based applications that can span multiple sites or domains with a range of SSO options, to help eliminate help-desk calls and other security problems associated with multiple passwords. By integrating with other SSO providers (such as Kerberos from a Microsoft domain logon, and client/server SSO solutions) Access Manager goes beyond 'reduced sign-on' to help implement a single authentication for the user across all system interactions.

Upgrade to Tivoli Federated Identity Manager to achieve standardized cross-domain SSO. The product supports a number of SSO federated identity and Web Services security standards, including Liberty Alliance specifications, SAML, WS-Federation, WS-Security and WS-Trust. This enables the company or the provider to interoperate and get SSO benefits from partners who implement any of these standards. Single Sign On (SSO) simplifies sign on for third-party users who typically have a primary relationship with their home organization. A federated business model enables a company to obtain trusted information about a third-party identity (such as customer, supplier, or a client employee) from that user's home organization without having to create, enroll, or manage a new account.

Reduce help-desk calls and other security problems associated with multiple passwords, using Tivoli Access Manager for e-business. Achieve a flexible SSO to Web-based applications that can span multiple sites or domains with a range of SSO options. By integrating with other SSO providers (such as Kerberos from a Microsoft domain logon, and client/server SSO solutions) Access Manager goes beyond 'reduced sign-on' to help implement a single authentication for the user across all system interactions.

Enhance user experience and reduced help desk costs, with one less password to remember. Use Tivoli Access Manager for e-business to achieve Microsoft desktop single sign on. Windows users can be automatically authenticated to applications protected by Access Manager for e-business.

Improve end-user experience through Single Sign On (SSO) implemented by Tivoli Federated Identity Manager.

Centralize the definition of users and provisioning of user services with the centralized administration of Tivoli Identity Manager. Role and rule-based delegated administration enables grouping of users according to business needs and delegation of administrative privileges along organizational and geographical boundaries.

Tivoli Identity Manager provisioning is integrated with access and identity. Access to Web applications and other applications can be determined by one user profile. The product interacts directly with users and with two external types of systems: identity sources and access control mechanisms. The identity systems deliver authoritative information about the users that need accounts. The provisioning system communicates directly with access control systems to create accounts, supply user information and passwords and define the entitlements of the account.

Pair Tivoli Identity Manager with WebSphere Process Server to achieve identity-based workflow. Streamlined automated workflow can decrease errors and inconsistency in business processes. Intelligent approval routing automates the submission and approval processes for access requests and changes to user information.

Federate disparate sources of identity data

Federated identity is a technology for brokering identities between companies or business units. Federated identity management is the set of business agreements, technical agreements and policy agreements that enable companies to partner to lower their overall identity management costs and improve user experience. It leverages the concept of a portable identity - the idea that your identity is not bound to a specific credential - to simplify the administration of users in a federated business relationship. Federation simplifies integration because there is a common way to share identities between companies and manage user sessions. Identity Federation services within a Service Oriented Architecture (SOA) ensure that users have simplified access and single sign on to the composite application environment.

Use these products in conjunction with WAS for additional capabilities.

Use Tivoli Access Manager for e-business to provide first-point-of-contact and session management that typically are prerequisites to federation with IBM Tivoli Federated Identity Manager.

Works with standards based, off-the-shelf products.

Reduce administration and provisioning costs related to managing identities for third-party users, with Tivoli Federated Identity Manager. Rather than having to enroll third-party users into a company's internal identity systems, federated identity management enables IT service providers to offload the cost of user administration to their business partner companies. Because the business partner company acts like an identity provider, the service provider does not have to take on the burden of user administration costs such as user enrollment, account management, password management, password reset, help desk, or customer care costs.

Simplify integration with a common way to share identities between companies and manage user sessions. Tivoli Federated Identity Manager facilitates "straight through processing" techniques because the identity provider does not have to replicate or stage business processes on behalf of a service provider. By employing Tivoli Access Manager for e-business (included with FIM), FIM is able to provide integrated session management, significantly facilitating inter-company transactions. With a federated identity model, identity providers have an opportunity to streamline inter-company transactions, thereby reducing costs, and simplifying integration.

SOA

SOA Management: Securing Web Services discusses the challenges of security in a Service Oriented Architecture (SOA). The security environment is still disjointedly hard wired into organizational silos segmented into network security, perimeter security, desktop security, server security and application security. Point solutions solve a partial need but they don't work in unison. Hence, they can't appreciably lower system risk, improve platform integrity, or mitigate the risk of broadening access. SOA adoption introduces new and unforeseen challenges with security integration, identity and security management.

  • Multiple Application Platforms (WebSphere, Microsoft or SAP)

  • Multiple Security Domains (internal, external, business unit silos, extranet)

  • Multiple Security Credentials (Kerberos, SAML, WS-Security, RACF)

  • Multiple Protocols (SOAP, HTTP/S, JMS, MQ)

  • Lack of "thread of identity" across the services context

Composite Applications must deal with the challenges of independent security and identity silos. The security solution needs to secure end user interactions as well service interactions (application to application). Security management needs to provide unified customer views for the composite application. The "thread" of user identity needs to be preserved end to end for auditing and compliance purposes.

Deliver policy-based integrated security management for SOA Web Services with Tivoli Federated Identity Manager.

Authorization services provided by Tivoli products in the Tivoli identity management solution ensure that SOA components can apply consistent authorization policies for Web, HTTP, and Java resources, Web Services, SOAP (WSDL resources), MQ (Queues and Queue Managers) and even core infrastructure platforms such as UNIX and Linux Servers.

Authorization services in an SOA is ensures that a common authorization abstraction model enables application platforms such as WebSphere, MS .NET, BEA and SAP to apply fine-grained authorization for these resource types.

Tivoli Access Manager for e-business implements a centralized policy service for SOA elements enabling business owners to delegate authorization decisions to a Policy server deployed in the SOA environment.

As SOA transactions originate across various channels and protocols it is important to have the centralized session management service of Tivoli Access Manager for e-business to enable various SOA components to have a "common view" of the current user session, for single sign on, single sign off, auditing and reporting, and so on.
