Web services are applications components that communicate using open XML-based standards and transport protocols to exchange data with calling clients. They are self-containing and self-describing and can be discovered using the Universal Description, Discovery, and Integration (UDDI). They can also be used by other applications and can be published, located, and invoked across the Web. HTTP and XML are the basis for Web services. The Java platform provides the XML and RESTful APIs and tools needed to quickly design, develop, test, and deploy web services and clients that fully interoperate with other web services and clients running on Java-based or non-Java-based platforms. REST (Representational State Transfer) is an architectural style which is based on web-standards and the HTTP protocol. The RESTFul web services are based on HTTP methods (POST, GET, PUT, DELETE). XML Web Services (JAX-WS) is used to develop Web services and is a part of the Java development Kit (JDK). JAX-WS technology is used with other technologies, either from the core group or more enhanced Web services. Security in web services is important as in any other communication technology. This due to the fact that businesses are willingly to perform transactions over the internet and do not require human presence as well. There are boundaries of interaction between communicating entities. This means that all security requirements such as authentication, access control, non-repudiation, data integrity, and privacy must be addressed by the underlying security technology: web services. This research paper will give details about the definition of Java web services, different types of web services, factors to consider when choose a specific type of web services an...

Security is a wide concept, it is a separated subject with its own theories, "which focus on the process of attack and on preventing, detecting and recovering from attacks" (William 1996). Certainly, these processes should be well organized in coping with the complex system issues. A coherent approach should be taken, which builds on established security standards, procedu...
In view of emergence in cloud computing and cloud based identity management providers, the need for implementing SAML protocol is imperative. In addition, with the proliferation of SaaS (Software as a Service), and other web based applications, identity management has become challenging for various enterprises. Handling so many usernames and passwords for your intranet, cloud, webmail, HR system, and other resources is nothing but bothersome especially when your workforce is huge. This is where SAML is desperately needed. Many hosted services providers support SAML for authentication including Google Apps, Salesforce.com, Zendesk and Zoho. Thousands of large enterprises have adopted it as their standard protocol for their communicating identities across their network environments.
My project mainly focuses on relatively new field of study in Information Technology known as cryptography. This topic will take an in-depth look at this technology by introducing various concepts of cryptography, a brief history of cryptography and a look at some of the cryptography techniques available today. This will have a close look at how we can use cryptography in an open-systems environment such as the Internet, as well as some of the tools and resources available to help us accomplish this.

Web IS. The importance of web led the classical information systems to transform in order to integrate with web technologies. This means that a web application can access an organization’s dataset. And as we mentioned above, this integration creates new data issues, like security and accessibility.
This is the information age. There are financial and corporate information, research and analysis, trends have lead the trend and military intelligence. Information classified as confidential, sensitive and critical. There are gleaning information extraction and automated tools. There are management solutions, such as content management, knowledge management and document management, information management collected for. There are different mechanisms for storing information storage. Finally, information security, there are tools and techniques. In this paper, three important types of security information we need to discuss, such as security information from hackers, during transit to ensure that information and the protection of information stored in the system can be lost or stolen. Finally, a brief about wireless security has been described here. The Internet has become the information superhighway. Evolving Internet and related technologies have allowed companies to communicate in new ways with all types of people and strategic organization. Over the years, there have been increased after the distinctive features of Internet connection. As needs change, the more powerful the service of humanity encountered, faster connections, and what can be done in the need for more flexibility. Initially, the service, such as a simple POP3-based email and Web access is the extent of an Internet connection. Today, we have a site-to-site virtual private network (VPN), clients and home users VPN, streaming media, Web-based training, wonderful Internet applications, e-commerce, and business-to-business extranet. Therefore, the development of the Internet to meet the needs of a variety of advanced human society. On the home front, fr...
Moreover, the Web services paradigm is expected to transform the Web into a distributed application-to-application networks. Web services landscape is in a constant state of change with core specifications almost mature and more widely accepted by users. But for some specific web service concept in the development of specifications exist. In addition, developers have started to use the primary Web service standards to be familiar with their distinguished opportunities in connectivity, interchangeable handle and easy to us
In this report, the author endeavours to present the how the security issues generally presented on the B2C web sites can assured by technical controls and educating customers. The report presents levels of end-to-end security components that include: physical system security, operating system security and network security. With advent of web applications that are now being used extensively for deploying e-commerce applications, author also presented the web security threat profile of web services that is currently an active research topic. All of the discussed components are attached with advice that can be provided to customers that may not apparent to them, but can help reduce security issues.
In the case of web-based applications software, it must include controls to protect the value of the business and its information from the exposure to end users in the outside world. There is this mediation between end users, the valuable data, and the outside world.
In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
This chapter provides an overview of cryptography concept. It`s required to encrypt and maintain confidentiality of the information to be transmitted over the network. This is achieved through cryptography. Cryptography plays a vital role in securing the information when transmitted across the network. It helps in maintaining the integrity of the information stored on the network. Thus, security is one of the important concepts to be explored in the world of network security.
The book is structured into four parts: Part 1 discusses the fundamentals of Internet security and privacy, Part 2 specializes in privacy while on the World Wide Web, Part 3’s topics are e-mail security and privacy, and Part 4 discusses the ways in which to secure a computer. Following the structure of the book, I will review and summarize the most important aspects of the parts and chapters in chronological order.
