Many organizations have now implemented solutions based on the promise of Web services, exposing those services over the Internet to enjoy maximum exposure—which then leaves them with the dilemma of securing their services to protect data and other resources. Find out how to use Java and Apache's Web Services Security for Java (WSS4J) framework to secure your Web services.

eb services have evolved into a standard means for integrating organizations using differing technologies running on heterogeneous systems and frameworks. A Web service is a business-logic component designed to be accessed across a network using industry-standard protocols and data formats. A Web service exposes a public interface described by a standard industry document format such as a WSDL file. This description document lets external systems understand and interact with the Web service over standard transport protocols such as HTTP, with messages encapsulated using standard message protocols such as SOAP.
Web services produce loosely-coupled systems that clients typically communicate with in a stateless, asynchronous manner, requiring no concern for the underlying protocol or location of the service. Unfortunately, this loosely-coupled, open communication environment is rife with potential security threats, as the next section illustrates.
