Oracle Identity and Access Management is a product set that allows enterprises to manage and automate the end-to-end lifecycle of user identities, and provides users with secure, fine-grained access to enterprise resources and assets. Oracle introduced the first product in this set, Oracle Internet Directory, in 1999. Since then, Oracle has developed and introduced a number of identity and access management features including directory synchronization, secure directory administration, and a Web single sign-on service, all of which were integrated with the Oracle product stack. In 2005 and 2006, Oracle further enhanced its identity and access management offerings through strategic acquisitions. Oracle has made significant investments in best-of-breed solutions for identity federation, Web access management, delegated identity administration, user identity provisioning and virtual directory technology.
