Design Considerations for Implementing Security in Web Services

the XML based web-service / application is checked by looking its IP address. The web service provider has to maintain a list with IP addresses, from which requests are valid. The provider compares the users IP address with the list. But IP blocking blocks access from all IP address expect those in the list, this means that not only the web service will be blocked from the user, also the WSDL, which potential customers can view for further information about the web service. An additional problem with this technique is that it requires administration of the Access IP list. If a specific web service is widely used, the IP list will grow large and more difficult to maintain. This also requires that the list is updated regularly to avoid revoked accesses. Also an unauthorized user can access to web service using IP spoofing.

Web Services: Architectural Styles and Design Considerations for REST API

Web Services: Architectural Styles and Design Considerations for REST API

Abstract: The issue of sharing real time data with others is paramount, especially in today’s digital age. We have lots of applications generating tons of data every minute. Each and every row of such data is useful either to the data generator or to a third party application. But we need a standard set of protocols to share data between applications over a network. This is where Application Programming Interfaces comes in. By using web services any application can share and read information automatically from other applications without human interference. This greatly advances the data sharing between applications, hence improving the services, productivity and user experience. We identified that soccer and sports in general pumps large amount of data into the internet, with no proper way to leverage it. Hence, we will be building a system, that collects this massive data from 1993 all the way up to the present time and will continue to do so automatically as long as there is data to mine, and a REST API on top of it so that the client/developers can access this data in a slick, automated, efficient and a fast way. This paper deals with various ways of leveraging data available online as well as an in detail comparison of the two major types of web services namely: SOAP & REST. It then goes on to detail the architectural styles and the design considerations to build REST API from scratch.

Security Patterns for Web Services Agile Architectures

Security Patterns for Web Services Agile Architectures

Because of several vulnerabilities in software products and high amount of damage caused by them, software developers are enforced to produce more secure systems. Software grows up through its life cycle, so software development methodologies should pay special attention to security aspects of the product. [7] Agile methodologies for security activities include applying agility measurement and applying an efficient agility reduction tolerance (ART). Using this approach method engineer of the project can enhance their agile software development process with security features to increase product’s trustworthiness. A secure system is one that is protected against specific undesired outcomes. Delivering a secure system, and particularly, a secure web application, is not easy. Integrating general-purpose information systems development systems with security development activities could be a useful means to support these difficulties. Agile processes, such as Extreme programming, are of increasing interest in software development. Most significantly for web applications, agile processes encourage and embrace requirements change, which is a desirable characteristic for web application development. Agile methods include Feature Driven Development (FDD) and mature security methods, namely risk analysis, and integrate them to address the development of secure web applications. This approach key feature includes: a process capable of dealing with the key challenges of applications development like decreasing life-cycle times and frequently changing requirements and an iterative approach to risk analysis that integrates security design throughout the development process.

A Review on Web Services and Security Issues

A Review on Web Services and Security Issues

that data mining and scoring tool providers require users to use provider-specific ways to invoke their services. The provider-specific approach could be a major factor affecting why data mining tools and applications are not currently as widespread as one might hope. Web services standards can address these proprietary issues. This paper discusses what web services are, in general, as well as in the context of data mining and scoring. One not-so- rigorous description of web services is as follows: A web service client passes a request in text while the service provider acts on the request and returns text to the client, all via the Web. Web services are identical in concept to this process. However, complicated web services often involve richer content as input than simple web page browsing with web services. XML is most often used to format the input. As to the output, the contrast between web browsing and web services is not about whether or not the content is complicated, but rather whether the format is HTML or not. Even though it is not entirely technically correct, one can view an HTML document as an instance of an XML document. However, HTML is particularly designed for web browser consumption, while an XML document is designed for a specific business need. It

The Authors have proposed a calculation for anticipating WSDL assaults which utilizes the current security gauges. For example, Public Key Infrastructure (PKI), Digital Signatures, and XML Encryption/Decryption benchmarks. These calculations utilize “Intelligent Security Engine” which can be arranged to distinguish any sort of WSDL assaults and implemented algorithm is tested by real time information as far as execution. XML (Extensible Mark-up Language) is used for exchange of information in web services. Author had focused on giving security to "distribute" and "discover" a portion of SOA design, i.e. ensuring WSDL operations so as to avoid assailants to assault web benefits by picking up preferred standpoint of deciphering WSDL content which is in plain content organization.

Data Privacy and Security using Web Services

Data Privacy and Security using Web Services

These benefits allow organizations to integrate disparate applications and data formats with relative ease. Web services are also versatile by design. They can be accessed by humans via a Web-based client interface, or they can be accessed by other applications and other Web services. A client can even combine data from multiple Web services to, for instance, present a user with an application to update sales, shipping, and ERP systems from one unified interface – even if the systems themselves are incompatible. Because the systems exchange information via Web services, a change to the sales database, for example, will not affect the service itself. Code re-use is another positive side-effect of Web services' interoperability and flexibility. One service might be utilized by several clients, all of which employ the operations provided to fulfil different business objectives. Instead of having to create a custom service for each unique requirement, portions of a service are simply re-used as necessary.

and study of secret writing (Deming, 1982). The basic objective of cryptography is to enable two peers (persons or computers) to communicate over an insecure channel while preserving the secrecy of the information. In this correspondence, the originated message is known as plaintext, while the coded message is referred to as the ciphertext. Confusion and diffusion (Schneier, 1996) are basic techniques used for obscuring the redundancies in a plaintext (diffusion disperses parts of the letters throughout the ciphertext, while confusion prevents the cryptanalyst from using ciphertext to figure out the secret encryption key). The process of transforming a plaintext into ciphertext is called encryption, and the process of turning ciphertext back to plaintext is called decryption. In general, a cryptosystem comprises five components: a plaintext message, a ciphertext message, a key, an encryption scheme, and a decryption scheme; and is characterized by (1) the type of operations used for transforming plaintext to ciphertext (these operations are bit-stream based or block-stream based); (2) the number and type of keys used (symmetric or secret key encryption, and asymmetric or public key encryption); and finally (3) the manner in which the plaintext is processed (block cipher scheme, in which an n-bit plaintext block is mapped onto an n-bit ciphertext, or stream cipher scheme, in which a plaintext stream is mapped onto a ciphertext stream). Cryptog- raphy methodologies are of two groups: (1) conventional cryptography [known as private key cryptosystems and public key cryptosystems; examples are Data Encryption Standard, Advanced Encryption Standard, Rivest-Shamir-Adleman algorithms (Stallings, 2003)]; and (2) nonconventional cryptography. The latter involves complex algebraic and theoretical problems that often require the use of a broad range of mathematical and computational intelligent techniques to be resolved (Meletiou, Tasoulis, & Vrahatis, 2003). One of these methods is the application of artificial neural networks in cryptog- raphy, which has just been explored in recent years (Meletiou, Tasoulis, & Vrahatis, 2002 and the references therein). This idea constitutes the foundation of the novel symmetric cipher design that is proposed in this chapter.

Architecting Secure Web Services using Model Driven Agile Modeling

Architecting Secure Web Services using Model Driven Agile Modeling

Our methodology for designing and composing services in a secure manner. In particular, we are concerned with Safety properties of service behavior. Services can enforce security policies locally and can invoke other services that respect given security contracts. This call-by-contract mechanism offers a significant set of opportunities, each driving secure ways to compose services. We discuss how we can correctly plan service compositions in several relevant classes of services and security properties. With this aim, we propose a graphical modeling framework in this project. Our formalism features dynamic and static semantics, thus allowing for formal reasoning about systems. Static analysis and model checking techniques provide the designer with useful information to assess and fix possible vulnerabilities.(Refer to Figure 5 below)

information along with the message content. Designed to achieve end-to-end security, the new standards have also been utilized by the NaradaBrokering [19] messaging infrastructure, a features rich and values added interoperable interface to Web services. These security centered standards, however, have brought about significant overheads to the use of service. Concerns about the operational performance of Web services security are legitimate because the new suite of XML specifications significantly enlarge SOAP size especially its header size. The lately added XML security elements not only make use of more network bandwidth as SOAP transports, they also demand additional CPU cycles at both the assembly-sender side and at the processing-receiver side. Their utilization into the messaging substrate is at debate. Therefore it's desirable to be able to examine the performance issue of Web services security, and it would be considered constructive to examine it based on the specific implementation, based on the actual data gathered from these implementations.

Web services security evaluation considerations

Web services security evaluation considerations

Web service-federation does not specify how security token exchanges can occur, given potential differences in the various domains’ methods for authenticating users and services. Moreover, the specification does not suggest strategies for establishing trust relationships between entities, for mapping differences in the trustworthiness of security tokens across domains, and designating authorities to maintain and to publish security definitions and requirements (Van Dyke, 2004). Current research suggests advanced approaches for designing dynamic web service trust networks that confront these issues. Specifically, it discusses how additional primary concepts (such as trust levels, trust groups and trust authorities) can enhance existing web service-* security specifications. Trust levels can be thought of as mutually recognised, standardised identifiers of the ‘level of trustworthiness’ for a given user or service. For example, an entity that interacts with a user who holds an authentication ticket signed by one of its trusted partners should be able to trust this user to some degree, as outlined by the entity’s trust policy. With these additions, systems can define dynamic trust policies and generate dynamic trust relationships. It is worth mentioning that proponents of web service believe that new web service technologies will expand federation as it exists for ATM networks into a generalised architecture that is applicable for many types of internet communications.

reduce the cost and effort associated with the introduction of security during implementation. At the architectural level a system must be coherent and present unified security architecture that takes into account security principles (such as principle of least privilege). Architectural Risk Analysis of Software Systems Based on Security Patterns, The importance of software security has been profound, since most attacks to software systems are based on vulnerabilities caused by poorly designed and developed software. Furthermore, the enforcement of security in software systems at the design phase can reduce the high cost and effort associated with the introduction of security during implementation. For this purpose, security patterns that offer security at the architectural level have been proposed in analogy to the well-known design patterns. The main goal of this paper is to perform risk analysis of software systems based on the security patterns that they contain. The first step is to determine to what extent specific security patterns shield from known attacks. This information is fed to a mathematical model based on the fuzzy-set theory and fuzzy fault trees in order to compute the risk for each category of attacks. The whole process has been automated using a methodology that extracts the risk of a software system by reading the class diagram of the system under study [Spyros T Halkidis].

Model Driven Architecture based Agile Modelled Layered Security Architecture for Web Services Extended to Cloud, Big Data and IOT

Companies have started the adoption of Web Service technology and the WS-Security specification as an approach to ensure the integrity of transmitted messages and data. The WS-Security specification is a joint effort by Microsoft, IBM, and VeriSign to address this most important issue. The WS-Security specification is designed to provide an extensible security implementation that will evolve as Web Services technology becomes more sophisticated. Both WS-Security and WSE 3.0 plays an important role when building Microsoft .NET- based Web Services or Web Services consumers. WS-Security integrates a set of popular security technologies, including digital signing and encryption based on security tokens, including X.509 certificates. It is flexible and is designed to be used as the basis for the construction of a wide variety of security models, including PKI, Kerberos and SSL. Particularly WS-Security provides support for multiple security tokens, multiple trust domains, multiple signature formats, and multiple encryption technologies. Table 3.3 provides Security concepts and security patterns in development phases.

accessed. The host name of web site (the URL) should match the topic name(s) of your SSL certificate. Netscape in 1996 has introduced transport Layer Security [16], having common name “Secure Sockets Layer (SSL)”. It consists of two main parts: The Record Layer encrypts/decrypts TCP data streams using the algorithms and keys negotiated in TLS Handshake, which is additionally used to authenticate the server and optionally the consumer. These days it is the foremost vital cryptographic protocol worldwide, since it is implemented in each internet browser. TLS offers various choices for key agreement, encryption and authentication of network peers, however most often the subsequent configuration is used: the online server is configured with a X.509 certificate that features its domain name. This certificate should be issued from a “trusted” certification authority (CA), where “trusted” means that the foundation certificate of this CA is included in nearly all internet browsers [22]. During the TLS Handshake, the server sends this certificate to the browser. The browser checks that the certificate comes from a “trusted” CA, which the domain name within the certificate matches the domain name contained within the requested URL. If each check succeeds, the browser continues loading the online page. If there is a haul, the human user is asked for a (security) call. The browser itself remains anonymous inside this TLS configuration. To authenticate the user, typically a username/password is requested by the server through an HTML form. This TLS configuration worked fine for all internet applications, until the primary Phishing attacks surfaced in 2004. In an exceedingly Phishing attack, the attacker lures the victim to a pretend website (either using spoofed emails or attacks on the DNS), where the victim enters username and password(s). This is possible even with TLS, since the human user fails to verify the authentication of the server via TLS [17].

Building Trust for Web Services Security Patterns

Building Trust for Web Services Security Patterns

Web services have acquired enormous popularity among software developers. This popularity has motivated developers to publish a large number of web service descriptions in UDDI registries. Although these registries provide search facilities, they are still rather difficult to use and often require service consumers to spend too much time manually browsing and selecting service descriptions. The availability of Internet and its services means that the information, the computing systems, and the security controls are all accessible and operable in committed state at some random point of time [1]. The inherent vulnerabilities of the internet architecture provide opportunities for a lot of attacks on its infrastructure and services. The growing emphasis on techniques for discovering relevant web services has dramatically increased the need for methods that let clients effectively find web services that are tailored to their requirements [2]. Such requirements can be functional (what the service offers) or non-functional (constraints on various properties such as quality of service, service reputation, interface semantics, and security). Because many web services will likely deliver similar functionalities, determining which are the most suitable without assessing their behavior under certain conditions will be challenging.
