WS-Policy
WS-Policy is a specification that allows web services to use XML to advertise their policies (on security, quality of service, etc.) and for web service consumers to specify their policy requirements. WS-Policy is a W3C recommendation as of September 2007. WS-Policy represents a set of specifications that describe the capabilities and constraints of the security (and other business) policies on intermediaries and end points (for example, required security tokens, supported encryption algorithms, and privacy rules) and how to associate policies with services and end points. Policy Assertion Assertions can either be requirements put upon a web service or an advertisement for the policies of a web service. Operator tags Two "operators" (XML tags) are used to make statements about policy combinations: *''wsp:ExactlyOne'' - asserts that only one child node must be satisfied. *''wsp:All'' - asserts that all child nodes must be satisfied. Logically, an empty ''wsp:All'' tag makes no ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WS-Policy4MASC
WS-Policy4MASC is a policy language for managing Web services and their composition. Overview WS-Policy4MASC extends a widely used industrial standard, WS-Policy, with information necessary for run-time management, including the unique support for autonomic business-driven IT management (BDIM). The specifications of diverse financial and non-financial business value metrics and business strategies that guide business-value driven selection among alternative control (adaptation) actions are the main distinctive characteristics and contributions of WS-Policy4MASC. WS-Policy4MASC also supports other management aspects, such as fault management and maximization of technical QoS metrics. It has built-in constructs for specification of a wide range of adaptations and events common in management of service-oriented systems and business process A business process, business method, or business function is a collection of related, structured activities or tasks performed by people or ...

WS-SecurityPolicy
WS-Security Policy is a web services specification, created by IBM and 12 co-authors, that has become an OASIS In ecology, an oasis (; : oases ) is a fertile area of a desert or semi-desert environmentWS-Security, WS-Trust and WS-Secure Conversation by offering mechanisms to represent the capabilities and requirements of web services as policies.

WS-SecureConversation
WS-SecureConversation is a Web Services specification, created by IBM and others, that works in conjunction with WS-Security, WS-Trust and WS-Policy to allow the creation and sharing of security contexts. Extending the use cases of WS-Security, the purpose of WS-SecureConversation is to establish security contexts for multiple SOAP message exchanges, reducing the overhead of key establishment. Features * Establish a new security context in following modes: ** Security context token created by a security token service (WS-Trust STS) ** Security context token created by one of the communicating parties and propagated with a message ** Security context token created through negotiation/exchanges * Renew security context * Amend Security context (add claims) * Cancel security context * Derive key: parties may use different keys per side and function (sign/encrypt), and change keys frequently to prevent cryptographic attacks * Maintain high secure context WS-SecureConversation is mean ...

WS-Security
Web Services Security (WS-Security, WSS) is an extension to SOAP to apply security to Web services. It is a member of the Web service specifications and was published by OASIS. The protocol specifies how integrity and confidentiality can be enforced on messages and allows the communication of various security token formats, such as Security Assertion Markup Language (SAML), Kerberos, and X.509. Its main focus is the use of XML Signature and XML Encryption to provide end-to-end security. Features WS-Security describes three main mechanisms: * How to sign SOAP messages to assure integrity. Signed messages also provide non-repudiation. * How to encrypt SOAP messages to assure confidentiality. * How to attach security tokens to ascertain the sender's identity. The specification allows a variety of signature formats, encryption algorithms and multiple trust domains, and is open to various security token models, such as: * X.509 certificates, * Kerberos tickets, * User ID/Password ...

Web Services
A web service (WS) is either: * a service offered by an electronic device to another electronic device, communicating with each other via the Internet, or * a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images). In a web service, a web technology such as HTTP is used for transferring machine-readable file formats such as XMLHttpRequest, XML and JSON. In practice, a web service commonly provides an Object database, object-oriented web-based interface to a database server, utilized for example by another web server, or by a Mobile app development, mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow Web syndication, syndication. Another application offered to the end-user may be a Mashup (web application hybrid), mashup, where a W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quality Of Service
Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as packet loss, bit rate, throughput, transmission delay, availability, jitter, etc. In the field of computer networking and other packet-switched telecommunication networks, quality of service refers to traffic prioritization and resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priorities to different applications, users, or data Traffic flow (computer networking), flows, or to guarantee a certain level of performance to a data flow. Quality of service is particularly important for the transport of traffic with special requirements. In particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WS-Trust
WS-Trust is a WS-* specification and OASIS standard that provides extensions to WS-Security, specifically dealing with the issuing, renewing, and validating of security tokens, as well as with ways to establish, assess the presence of, and broker trust relationships between participants in a secure message exchange. The WS-Trust specification was authored by representatives of a number of companies, and waapproved by OASISas a standard in March 2007. Using the extensions defined in WS-Trust, applications can engage in secure communication designed to work within the Web services framework. Overview WS-Trust defines a number of new elements, concepts and artifacts in support of that goal, including: * the concept of a Security Token Service (STS) - a web service that issues security tokens as defined in the WS-Security specification. * the formats of the messages used to request security tokens and the responses to those messages. * mechanisms for key exchange WS-Trust is t ...
