Service-oriented architecture (SOA) is a widely adopted architecture that uses web services, which have become increasingly important in the development and integration of applications. Its purpose is to allow information system technologies to interact by exchanging messages between sender and recipient using the simple object access protocol (SOAP), an XML document, or the HTTP protocol. We will attempt to provide an overview and analysis of standards in the field of web service security, specifically SOAP messages, using Kerberos authentication, which is a computer network security protocol that provides users with high security for requests between two or more hosts located in an unreliable location such as the internet.Everything that has to do with Kerberos has to deal with systems that rely on data authentication.

ARGOS is a web service we implemented to offer face recognition Authentication Services (AaaS) to mobile and desktop (via the web browser) end users. The Authentication Services may be used by 3rd party service organizations to enhance their service offering to their customers. ARGOS implements a secure face recognition-based authentication service aiming to provide simple and intuitive tools for 3rd party service providers (like PayPal, banks, e-commerce etc) to replace passwords with face biometrics. It supports authentication from any device with 2D or 3D frontal facing camera (mobile phones, laptops, tablets etc.) and almost any operating systems (iOS, Android, Windows and Linux Ubuntu).

Web Service Architecture gives a compatible and scalable structure for web service interactions with performance, responsiveness, reliability and security to make a quality of software design. Systematic quantitative approaches have been discussed for designing and developing software systems that meet performance objectives. Many companies have successfully applied these techniques in different applications to achieve better performance in terms of financial, customer satisfaction, and other benefits. This paper describes the architecture, design, implementation, integration testing, performance and maintenance of new applications. The most successful best practices used in world class organizations are discussed. This will help the application, component, and software system designers to develop web applications and fine tune the existing methods in line with the best practices. In business process automation, many standard practices and technologies have been used to model and execute business processes. The emerging technology is web applications technology which provides a great flexibility for development of interoperable environment services. In this paper we propose a Case study of Automatic Gas Booking system, a business process development strategy and best practices used in development of software components used in web applications. The classification of QWS dataset with 2507 records, service invocations, integration and security for web applications have been discussed.

In this ubiquitous IoT (Internet of Things) era, web services have become a vital part of today's critical national and public sector infrastructure. With the industry wide adaptation of service-oriented architecture (SOA), web services have become an integral component of enterprise software eco-system, resulting in new security challenges. Web services are strategic components used by wide variety of organizations for information exchange on the internet scale. The public deployments of mission critical APIs opens up possibility of software bugs to be maliciously exploited. Therefore, vulnerability identification in web services through static as well as dynamic analysis is a thriving and interesting area of research in academia, national security and industry. Using OWASP (Open Web Application Security Project) web services guidelines, this paper discusses the challenges of existing standards, and reviews new techniques and tools to improve services security by detecting vulnerabilities. Recent vulnerabilities like Shellshock and Heartbleed has shifted the focus of risk assessment to the application layer, which for majority of organization means public facing web services and web/mobile applications. RESTFul services have now become the new service development paradigm normal; therefore SOAP centric standards such as XML Encryption, XML Signature, WS-Security, and WS-SecureConversation are nearly not as relevant. In this paper we provide an overview of the OWASP top 10 vulnerabilities for web services, and discuss the potential static code analysis techniques to discover these vulnerabilities. The paper reviews the security issues targeting web services, software/program verification and security development lifecycle.

Web Services can be invoked from anywhere through internet without having enough knowledge about the implementation details. In some cases, single service cannot accomplish user needs. One or more services must be composed which together satisfy the user needs. Therefore, security is the most important concern not only at single service level but also at composition level. Several attacks are possible on SOAP messages communicated among Web Services because of their standardized interfaces. Examples of Web Service attacks are oversize payload, SOAPAction spoofing, XML injection, WS-Addressing spoofing, etc. Most of the existing works provide solution to ensure basic security features of Web Services such as confidentiality, integrity, authentication, authorization, and non-repudiation. Very few of the existing works provide solutions such as schema validation and schema hardening for attacks on Web Services. But these solutions do not address and provide attack specific solutions for SOAP messages communicated between Web Service. Hence, it is proposed to provide solutions for two of the prevailing Web Service attacks. Since new types of Web Service attacks are evolving over time, the proposed security solutions are implemented as APIs that are pluggable in any server where the Web Service is deployed.
 

Web Service (WS) plays an important role in today's word to provide effective services for humans and these web services are built with the standard of SOAP, WSDL & UDDI. This technology enables various service providers to register and service sender their intelligent agent based privacy preserving modelservices to utilize the service over the internet through pre established networks. Also accessing these services need to be secured and protected from various types of attacks in the network environment. Exchanging data between two applications on a secure channel is a challenging issue in today communication world. Traditional security mechanism such as secured socket layer (SSL), Transport Layer Security (TLS) and Internet Protocol Security (IP Sec) is able to resolve this problem partially, hence this research paper proposes the privacy preserving named as HTTPI to secure the communication more efficiently. This HTTPI protocol satisfies the QoS requirements, such as authentication, authorization, integrity and confidentiality in various levels of the OSI layers. This work also ensures the QoS that covers non functional characteristics like performance (throughput), response time, security, reliability and capacity. This proposed intelligent agent based model results in excellent throughput, good response time and increases the QoS requirements.
