Web Services: Security Software
built 282 days ago
The fundamental roles in Web Services are service providers, service requesters, and service brokers. These roles have operations: publish, find, and bind. Operation intermediation occurs through environmental prerequisites, and it introduces aspects such as security, workflow, transactions, billing, quality-of-service, and service level agreements. The mechanism of service description language is key to fundamental operations in Web Services. A complete description of a Web Service appears in two separate documents: a Network-Accessible Service Specification Language (NASSL) document and a Well-Defined Service (WDS) document.

Various environmental aspects must ... be considered when designing Web Services. For example, the security requirements for services brokers will vary depending upon the deployment environment. Most intranet deployments have minimal security requirements but in situations where high-value B2B transactions are conducted, much higher security may be necessary. An approach is to take a risk-assessment view of security and design brokers to provide different levels of information based upon an environment's security infrastructure. (For more information about Web Services security considerations, see the Appendix.) Future releases of the Web Services toolkit will support some or all of these security considerations.
