Identify & Authorize

Property	Description
Condition	Specifies the condition operator for the identification and authentication types. Select any of the following condition operators: AND. Applies all the identification and authentication types. OR. Applies one of the selected identification and authentication types. Note: Even though this policy provides the option of choosing an AND or OR operation between the different identification and authentication types, the operation across the different policies in the IAM stage is always AND.
Allow anonymous	Specifies whether to allow all users to access the API without restriction. When you add a security policy and configure Allow anonymous, all requests are allowed to pass through to the native API, but the successfully identified requests are grouped under the respective identified application, and all unidentified requests are grouped under a common application named asDefaultApplication (sys:defaultApplication). While you allow all requests to pass through you can perform all application-specific actions, such as, viewing the runtime events for a particular application, monitor the service level agreement for a few applications and send an alert email based on some criteria like request count or availability, and throttle the requests from a particular application and not allow the request from that application if the number of requests reach the configured hard limit within configured period of time.
Identification Type. Specifies the identification type. You can select any of the following.
API Key	Specifies using the API key to identify and validate the client's API key to verify the client's identity in the registered list of applications for the specified API. Select one of the Application Lookup condition: Registered applications. Identifies the client's API key against the API key of all the applications registered to the API. On successful identification, API Gateway allows access to the API. Global applications. Identifies the client's API key against the API key of all the applications available in API Gateway. On successful identification, API Gateway allows access to the API. Global applications and DefaultApplication. Identifies the client's API key against all the applications available in API Gateway. Even though, if no global application is identified, API Gateway allows access to the API as default application. When this option is selected, you can use the API key as: Header parameter to consume an API. For example, x-Gateway-APIKey:a4b5d569-2450-11e3-b3fc-b5a70ab4288a Query parameter to invoke an API resource. For example, http://pie-3HKYMH2:5555/gateway/PetstoreAPI/1.0.3/store/ inventory?APIKey=faab7ac6-97a4-4228-908d-f1930faba470

Global applications and DefaultApplication. Identifies the client's hostname against the hostname identifier of all the applications available in API Gateway. If no global application is identified, then API Gateway allows access to the API as default application. Note: If the client request has X-Forwarded-For header, then API Gateway resolves the hostname from the IP address present in the X-Forwarded-For header. Else, API Gateway resolves the hostname from the client's IP address.

On successful authentication and identification, API Gateway allows access to the API. Global applications and DefaultApplication. 1. Authenticates the user and identifies the user against username identifier of all the applications available in the API Gateway. 2. On successful authentication and if no global application is identified, then API Gateway allows access to the API as default application. 3. In case if the authentication fails, then API Gateway does not allow access to the API. If Global applications and DefaultApplication and Allow anonymous are selected: 1. Authenticates the user and identifies the user against username identifier of all the applications available in the API Gateway. 2. On successful authentication and if no global application is identified, then API Gateway allows access to the API as default application. 3.

Note: You can use the claims in the JWT for further processing using request transformation policy.
Kerberos Token	Specifies using the Kerberos token to identify the client, extract the client's credentials from the Kerberos token, and verify the client's identity against the specified list of applications in API Gateway. Note: You have to enforce the Inbound Auth - Message policy with the property, Kerberos Token Authentication, configured, so when Identify & Authorize policy is executed, the user details fetched are used to match with application's data to identify the application.

SSL Certificate	Specifies using the SSL certificate to identify the client, extract the client's identity certificate, and verify the client's identity (certificate-based authentication) against the specified list of applications in API Gateway. The client certificate that is used to identify the client is supplied by the client to API Gateway during the SSL handshake over the transport layer or is added in the header of the request. The certificate included in the custom header can be in the following formats: Base64 encoded PEM certificate with BEGIN CERTIFICATE and END CERTIFICATE delimiters Non-Base64 encoded PEM certificate with BEGIN CERTIFICATE and END CERTIFICATE delimiters. PEM certificate can be without BEGIN CERTIFICATE and END CERTIFICATE delimiters if a single certificate is added. URL encoded PEM certificate with BEGIN CERTIFICATE and END CERTIFICATE delimiters. URL encoded PEM certificate can be without the BEGIN CERTIFICATE and END CERTIFICATE delimiters if a single certificate is added. If the transport protocol is HTTP then API Gateway checks for the existence of a header and fetches the certificate from the certificate header. If the certificate is coming from the custom header, then API Gateway does not check the validity of the certificate. API Gateway identifies the application using the certificate. The certificate should be validated by some external entity before sending it to API Gateway in a custom header. If the transport protocol is HTTPS then API Gateway first tries to identify the application based on the certificate exposed by the client during the SSL handshake. If there is no client certificate or the identification based on the client certificate fails API Gateway tries to identify based on the certificate provided in the header. The header name is customizable and can be customized in the extended settings property, customCertificateHeader, the default value being X-Client-Cert. Select one of the Application Lookup condition: Registered applications. Identifies the client's certificate against the client certificate identifier of all the applications registered to the API.
