Oracle Adaptive Access Manager provides superior protection for businesses and their customers through strong yet easy-to-deploy multifactor authentication and proactive, real-time fraud prevention.

Oracle Entitlement Server Evolving business and regulatory conditions can drive changes to the security and regulatory policies that govern your business. However, for most applications these policies are embedded in their code, making it difficult to change, and nearly impossible to monitor and audit. Oracle Entitlements Server (formerly BEA AquaLogic Enterprise Security) externalizes and centralizes fine-grained authorization policies for enterprise applications and web services. This is achieved via comprehensive, reusable, and fully auditable authorization policies and a simple, easy-to-use administration model.

Oracle Identity Federation is an industry-leading federation solution providing a self-contained and flexible multi-protocol federation server that can be rapidly deployed with your existing identity and access management systems. Support for leading standards-based protocols ensures interoperability to share identities across vendors, customers, and business partners without the increased costs of managing, maintaining, and administering additional identities and credentials.

Oracle Virtual Directory The first step in deploying a secure application is often to consolidate or synchronize all the user-identity sources that the new application will access. Oracle Virtual Directory eliminates this difficult step. It does this by accessing identity information contained in several identity sources, such as LDAP-enabled directories and databases, and presenting it to the application as one data source.

Oracle Role Manager In today’s regulatory compliance environment, organizations need a holistic view of their business users, job functions, and associated entitlements. Attempting this manually often results in chaos, frustration, and failed projects. Oracle Role Manager provides enterprise class role lifecycle management capabilities, helping strengthen regulatory compliance, and alleviating associated costs. It acts as the authoritative source for the relationships between business users, organizations, and entitlements, thus enabling automation of role based provisioning and access control across the IT infrastructure. This also provides enterprise applications rich role information enabling automation of business transactions for approval and routing.

Oracle Internet Directory : The past decade has seen an explosion in the number of web-based applications. To gain control over the vast number of user accounts within these applications, many companies have deployed one or more LDAP directories. These often require multiple security systems to secure physical access, to secure legacy applications, and to secure network access. Oracle offers state-of-the-art LDAP directory services as well as integrated supporting technologies that allow large enterprises to provide greater directory functionality in a wide array of deployments.

Oracle Access Manager allows users of your applications or IT systems to log in once and gain access to a broad range of IT resources. Oracle Access Manager provides an identity management and access control system that is shared by all your applications. The result is a centralized and automated single sign-on (SSO) solution for managing who has access to what information across your entire IT infrastructure.
