Web Service overview

Web Service is a self-contained, self-describing application component that communicates with other web-based applications using open protocol. Web Service allows different applications and platforms to link their data and reuse application-components.

IEC can function as a Web Service server. In PA tool, an IEC administrator defines the server settings and Web Service definitions. Then, the payloads of the received Web Service invocations are extracted and then sent for detection. To be able to generate an appropriate response, add the Send Web Service process step in your process flow.

A basic Web Service platform consists of XML+HTTP. The XML part is used to code and decode data. SOAP encodes the information in Web Service request and response messages before sending them over HTTP.

A Web Service Description Language (WSDL) file contains an XML coding of network services as collections of communication endpoints. This schema is a documentation of distributed systems and required details in applications communication which can be used in message exchange.
