A current IBM Tivoli security customer is very satisfied with their current IBM Tivoli Identity
Manager (ITIM) and IBM Tivoli Access Manager (ITAM) implementations. The customer has
benefited greatly from the user management and provisioning, authentication, authorization and
Web single sign-on processes now in place. The customer sees the value of Web services and
wants to leverage their business partnerships to greatly expand their online services, for a
relatively small investment. They are expecting that their existing ITIM and ITAM investments can
simply be stretched to include these business-to-business (B2B) flows. IBM Tivoli Federated
Identity Manager should be added to this scenario to address which security requirement?

A.
The blocking of threats that might otherwise cross enterprise boundaries

B.
The handling of potentially millions of users, which neither ITIM nor ITAM was built to address

C.
The integration with firewalls that control security between any two businesses involved in
these B2B flows

D.
The handling of multiple types of standards-based protocols and user tokens that need to be
passed between participating businesses
