Web Service Security Management

An HTTP client filter, transport layer security, and message layer security can provide secure data transfer and authorized data access for a web service. When you configure message layer security, the Data Integration Service can pass credentials to connections.

You can configure the following security option for a REST web service:

Is Authentication Required: Enables basic authentication for the REST web service. Basic authentication requires that each web service request includes a user name and a password to the domain. Enable the property from the Data Integration Service in the Administrator tool. Click

isAuthenticationRequired
. When authentication is required, each GET request requires a user name and password before the REST web service returns a response. Default is disabled.

You can configure the following security options for a SOAP web service:

HTTP Client Filter: If you want the Data Integration Service to accept requests based on the host name or IP address of the web service client, use the Administrator tool to configure an HTTP client filter. By default, a web service client running on any machine can send requests.
Message Layer Security: If you want the Data Integration Service to authenticate user credentials in SOAP requests, use the Administrator tool to enable WS-Security and configure web service permissions. The Data Integration Service can validate user credentials that are provided as a user name token in the SOAP request. If the user name token is not valid, the Data Integration Service rejects the request and sends a system-defined fault to the web service client. If a user does not have permission to execute the web service operation, the Data Integration Service rejects the request and sends a system-defined fault to the web service client.
Transport Layer Security (TLS): If you want the web service and web service client to communicate using an HTTPS URL, use the Administrator tool to enable transport layer security (TLS) for a web service. The Data Integration Service that the web service runs on must also use the HTTPS protocol. An HTTPS URL uses SSL to provide a secure connection for data transfer between a web service and a web service client.
Pass-Through Security: If an operation mapping requires connection credentials, the Data Integration Service can pass credentials from the user name token in the SOAP request to the connection. To configure the Data Integration Service to pass credentials to a connection, use the Administrator tool to configure the Data Integration Service to use pass-through security for the connection and enable WS-Security for the web service.
You cannot use pass-through security when the user name token includes a hashed or digested password.
