The Oracle Access Management platform enables Identity Context data to be collected, propagated across the involved components, and made available for granting or denying authorization to access protected resources.
For more information, see Figure 55-2. The Identity Context Service allows access to the Identity Context Runtime through the Identity Context API. The Identity Context Dictionary schema specifies the Identity Context attributes.
This section describes the following topics:
At the core of the Identity Context architecture is the Identity Context Dictionary. The dictionary defines the Identity Context schema by specifying the identity context attributes as defined by the Oracle Access Management platform.
The Schema describes each attribute with a unique name that equals namespace : attribute. Table 55-1 documents the Schema attributes.
Note:
Virtual attributes (as documented in Table 55-1) represent an abstract class of identity information from which specific attributes are created. When publishing virtual attributes, the Identity Context API expects the attribute value to contain attr-name=attr-value. The actual attribute will be created using the name namespace : attribute : attr-name and a value of attr-value. This approach allows the publication of attributes whose value comes from a source not directly managed by the Oracle Access Management components.

The Oracle Access Management platform leverages a common infrastructure component called the Context Management Engine (CME). CME ensures that an Identity Context is generated for every transaction that is processed through the Oracle Access Management platform. The context data gathered by CME applies to transactions a user performs over the web channel or web service channel and using many of the software products available in the Oracle Access Management platform. Some transactions that are initiated on the back end may also require access to Identity Context, and may require Identity Context to be persisted for some duration of time.
In a typical Oracle middleware deployment the Identity Context Runtime will be utilized primarily by the Oracle Access Management platform to perform policy-based decisions on behalf of protected applications. However, it is also possible for any applications running in the container to directly integrate with, and consume, the Identity Context Runtime by leveraging the Identity Context API. The amount of available Identity Context data will vary depending on what products have been deployed. There will be a default set of Identity Attributes that will be available out-of the box, which are mainly configured in the Access Manager by leveraging the Identity Assertion. Table 55-1 documents these default attributes. The following list provides details on the end-to-end flow of the Identity Context Runtime. Figure 55-3 below the list illustrates the flow.
Process overview: End-to-end flow of the Identity Context Runtime
User accesses a protected application from a device.
Access Manager asserts the identity, collects Identity Attributes from the participating Access Management publishing components and creates an Identity Context.
Access Manager generates an Identity Assertion (a SAML Session token) and incorporates the Identity Context attributes. The Access Manager Identity Asserter processes the Identity Assertion and publishes the Identity Context to the WebLogic Server container using the OPSS Attribute Service.
The protected application calls the OES PEP API to make an authorization decision. OES automatically propagates the Identity Context to the local OES PDP.
OES finds the appropriate Authorization Policy and evaluates it's Conditions (based on the Identity Context attributes). Evaluation can be done using a built-in Identity Context function or a custom function.
The protected application makes a JRF web service call in which the Oracle Web Service Manager (OWSM) client uses the SAML token to propagate Identity Context into the Web Service application environment.
OWSM (on the web service side) processes the SAML assertion with the Identity Context and publishes the Identity Context to the WebLogic Server container by using the OPSS Attribute Service.
Web Service application calls OES PEP API to make an authorization decision.
OES automatically propagates Identity Context to the remote OES PDP where conditions based on Identity Context attributes are evaluated using a built-in Identity Context function or a custom function.
Figure 55-3 Identity Context Process Flow
Once CME propagates Identity Context into the application tier and underlying Application Server container, the Identity Context is then made available to the container and applications running in it. Table 55-2 documents which Access Management platform products do what when working with Identity Context.
Table 55-2 Mapping Identity Context Operations
Role and Context Operation | Description | Components |
---|---|---|
Publisher - publishes Identity Context |
Trusted security framework protecting an application component obtains from another trusted security framework, or derives from the information available to it, suitable facts about the identity and/or identity's access request. The information collected by the authoritative component is based on the environmental context available to component's runtime framework. For example, Access Manager determines the user's level of authentication strength, OAAM computes the risk score associated with a specific online session, and OESSO determines whether or not the client device has a firewall enabled. |
|
Propagator - propagates Identity Context |
Trusted security framework propagates Identity Context attributes for use by another application security framework or directly by the application. For example, OAAM propagates user's risk score into the Access Manager session for the user, Access Manager propagates Identity Assertion (SAML token) for with the authenticated user's unique id and authentication level, and OWSM client propagates the current Identity Context over to the web service where OWSM agent will rebuild Identity Context in the web service application. |
|
Evaluators - evaluate Identity Context |
Trusted security framework or end-user application using Identity Context attributes to perform policy decisions or personalize application business logic. For example, when OAAM is present and configured to compute the risk score, the application's authorization policy in OES allows access only when the risk score is under a certain threshold. Also, when Identity Federation in Access Manager is configured, the application uses a partner-supplied assertion (available in the Identity Context) to authorize access to a transaction using OES. |
