1.0 Introduction to McAfee Cloud Identity Manager

McAfee® Cloud Identity Manager (Cloud Identity Manager, formerly Intel® Expressway Cloud Access 360-SSO) simplifies the management and secures the use of cloud, Software as a Service (SaaS), and web applications for companies and large organizations. Service and application providers can also use Cloud Identity Manager to simplify and improve the authentication process for their customers.

Cloud Identity Manager provides support for the following features:• Extensible framework• Web single sign on (SSO)• Multiple authentication methods• Credential mapping and user provisioning• Authorization policies and access control enforcement• Event auditing and monitoring• Connectors for popular cloud services and applications• Web-based Management Console

Cloud Identity Manager runs as a stand-alone server and is configured by an administrator using a web-based Management Console accessible from a web browser. For information about installing Cloud Identity Manager as a standalone server or as a cluster of servers, see the McAfee Cloud Identity Manager Installation Guide. For information about configuring Cloud Identity Manager in the Management Console, see the McAfee Cloud Identity Manager Product Guide.

Cloud Identity Manager provides connectors for many popular cloud services and applications, including Google Apps and Salesforce.com. These connectors are built in to Cloud Identity Manager and simplify the deployment of the cloud service or application in an organization. Web SSO requires configuration in the Management Console and in the cloud application’s user interface. Instructions for configuring SSO on the cloud application side are included in the documentation set.

For customers who have Java-based or .NET web applications that do not support SAML2 authentication, Cloud Identity Manager provides a custom connector. For information about integrating Java-based and .NET web applications with Cloud Identity Manager, see the McAfee Cloud Identity Manager Integration Guide.

For software developers who want to write their own cloud service connectors or authentication modules, Cloud Identity Manager provides an SDK. For more information about the SDK, see the McAfee Cloud Identity Manager Developer’s Guide.

For example, a name that identifies the Cloud Connector-Identity Connector combination is more useful than a URL, which can change.

4. Click Next.The Identity Connector step opens.

3.2 Specifying an Identity ConnectorTo specify an Identity Connector, you select an existing Identity Connector or create a new one.

There are six types of Identity Connectors:• LDAP• Integrated Windows Authentication with Active Directory (IWA-AD)• ECA360 Token Authentication• Authentication Chain• SAML2 Proxy• Central Authentication Service (CAS)

For LDAP and IWA-AD Identity Connectors, identity information is retrieved from an identity store. To configure these Identity Connectors, you specify the ID of the identity store containing the identity information and how to search the specified identity store. To specify the search, you configure the following LDAP parameters:

• Base DN — Specifies where to start searching in the LDAP tree• Search Attribute — Specifies the user attribute to retrieve from the identity store• Search Scope — Specifies how many levels to search in the LDAP tree below the Base DN

For CAS and other Identity Connectors, identity information is retrieved from an authentication result provided by an external authentication service. To configure one of these Identity Connectors, you specify fields specific to each connector type.


3.2.1 Select an Existing Identity Connector

If the Identity Connector is already configured, you can select it on the Identity Connector step of the Cloud Connector wizard. The settings on this step depend on the Identity Connector you select. For example, the Enable Additional Authentication Module(s) area is only displayed when the following conditions are met:

• The selected Identity Connector type is an authentication chain.• When the authentication chain was created, one or more authentication modules were configured

as Determined by Cloud Connector on the Policy Setting step of the Authentication Module wizard. To enable these modules, select the checkboxes in the Enable Additional Authentication Module(s) area. For more information, see the McAfee Cloud Identity Manager Product Guide.

• $AuthnResult.isIPInRangeTests whether the client computer’s IP address falls within the specified range.

Syntax: $AuthnResult.isIPInRange(low_IP,high_IP,target_IP)Parameters

low_IP — Specifies the beginning value of the IP address range.high_IP — Specifies the ending value of the IP address range.target_IP — Specifies the IP address of the client computer seeking access to the application.

Return ValueReturns one of the following values:TRUE — The client IP address falls within the specified range.FALSE — The client IP address does not fall within the specified range.

— Built-in Library Variable — Select one of the following built-in variables:• $IP — Specifies the IP address of the client computer seeking access to the application.• $UserAgent — Specifies the web browser’s user agent which provides information about

whether the browser is running on a personal computer or mobile device.— AuthnResult — Select an attribute from the AuthnResult drop-down list.

Example: mailExpression: $AuthnResult.getField("mail")Note: This attribute is an authentication result output by the Identity Connector or by the preceding authentication module in an authentication chain.

— Operator — Select an operator from the Operator drop-down list.Example: containsExpression: $AuthnResult.getField("mail") containsNote: The available operators are: ==, !=, >, <, >=, <=, contains, &&, ||, or, ~=, +, -, *, %, /, and =.

3.5.4 Expression editor examples

The following examples show how to build an expression using the expression editor.

Expression editor: example 1

The expression in the following example retrieves the attribute corporation from the authentication results and compares its value to the empty string on the right side of the expression. If the expression evaluates to TRUE, the user is not part of any corporation. If the Rule Effect is set to Deny, the user is denied access to the SaaS or web application.

To create this expression:1. Select the attribute corporation from the AuthnResult drop-down list.2. Select the operator == from the Operator drop-down list.3. Type the double quotes in the Expression editor field.4. Click OK.


Expression editor: example 2

The expression in the following example uses the built-in library function $AuthnResult.isIPInRange and the built-in library variables: $IP and $UserAgent. The expression evaluates to TRUE if one or more of these conditions are met:

• The client computer IP address falls within the specified range.• The client computer IP address equals the specified value.• The web browser is running on an iPhone.

If the expression evaluates to TRUE and the Rule Effect is set to Permit, the user is granted access to the SaaS or web application.

To create this expression:1. Select $AuthnResult.isIPInRange from the Built-in Library Function drop-down list.2. Type the low and high IP addresses that specify the range inside the first two pairs of quotes inside

the parentheses.3. Replace the third pair of quotes with the Built-in Library Variable $IP, which is the IP address of

the client computer seeking access to the application.4. Select the operator || from the Operator drop-down list.5. Select $IP from the Built-in Library Variable drop-down list.6. Select the operator == from the Operator drop-down list.7. Type an IP address enclosed in quotes in the Expression editor field.8. Select the operator || from the Operator drop-down list.9. Select $UserAgent from the Built-in Library Variable drop-down list.10. Select the operator contains from the Operator drop-down list.11. Type “iPhone” (including the quotes) in the Expression editor field.12. Click OK.
