Issues and challenges in web services in the 21^st century

Web Services Security (WS-Security) is the emerging security standard designed to address these issues. Web services are a widely touted technology that aims to provide tangible benefits to both business and IT. Their increasing use in the enterprise sector for the integration of distributed systems and business critical functions dictates the need for security assurance yet there is currently no security testing methodology specifically adapted to applications that implement web services. Web Service Enhancement (WSE) allows you to implement message level security solutions including authentication, encryption and digital signatures. In this paper we analyze the threats and security issues that can be related to the use of web services technology in a web application.
