Securing Web Services

Date: Wednesday, March 2005
Presenter: Paul Greenfield

Web Services are widely seen as a transforming technology, one that will finally allow the complete integration of computer systems and business processes, greatly reducing costs and improving efficiency. Security is widely seen as the principal factor impeding the adoption of these technologies and organisations must overcome a broad range of security issues before they expose parts of their business processes as Web Services to their key suppliers and business partners.

This talk discussed:

• What is meant by securing Web Services? What capabilities are you going to need to let you protect your critical services and sensitive information?
• How can you implement secure Web Services today and why are new standards needed to provide even stronger security?
• Examining and demonstrating the use of the Web Services Security standards family
• The lessons learnt from building a multi-party integrated application
• The performance and resource implications of securing your Web Services applications

An Introduction to XML

Date: Wednesday, February 2005
Presenter: Nigel Eke

This presentation will provide the attendees with a quick start to understanding XML. Nigel will also touch on the basics of XML Namespaces, XSLT and XML Schema.

This is an ideal opportunity if you are trying to come up to speed with Web Services and haven't quite grasped XML.

Does the * in WS-* now stand for WS-Bloat?

Date: Wednesday, November 2004
Moderator: Bill Donoghoe
Panel:
Dr Boualem Benatallah, UNSW
Dr Hao He, Thomson Corporation
Dr Jim Webber, University of Newcastle on Tyne
Raymond Wong, UNSW

An expert panel will lead a discussion about a whether or not the increasing number and complexity of Web Services standards is bad.

To quote Albert Einstein

"Things should be made as simple as possible, but no simpler."

How simple should Web Services be?

Interoperability Challenges in Service-Oriented Architectures

Date: Wednesday, 6th October 2004
Presenter: Dr. Boualem Benatallah (Senior Lecturer UNSW)

The emerging next-generation Web technologies, centred on the concept of Web services, promise to enable interactions and efficiencies that have not been experienced before. The foundation of this technology lies in the modularization and virtualization of system functions as services that:

1. can be described, advertised and discovered using (XML-based) standard languages, and
2. communicate through standard Internet protocols.

This talk examines some of the interoperability challenges in service-oriented architectures. While much progress has been made toward providing basic interoperability at the communication layer, there is still a lot to be done. Interoperability is more pronounced in service-oriented architectures than usual partly because services are typically developed by different organizations, and the difficulties created by services' autonomy and heterogeneity. We highlight interoperability aspects at higher level of abstractions including content and business process layers. Finally, we will discuss several open research issues in facilitating large-scale interoperation among Web services.

What is Service Oriented Architecture?

Date: Wednesday, 1st September 2004
Panel: Bill Donoghoe and Dr Hao He

A SIG forum with an expert panel to answer questions from the floor about Service Oriented Architecture.
With plenty of input from the floor of the meeting, a broad range of topics were covered. Some of the questions asked were:

1. Is SOA more generic than solely WS? For example does CORBA support SOA?
2. Is SOA a problem in itself?
3. What are the applicable standards for SOA?
4. What is a service?
5. Is it bad form to put state into a service?
6. What is the difference between SOA and Enterprise Service Bus(ESB)?
7. How do you handle transactions in SOA?

How to build SOA applications effectively?

Date: Wednesday, 4th August 2004

Presenter: Dr. Hao He
Venue: Level 4,
122 Castlereagh Street,
Sydney 2000
Time: 6 pm - 7.30 pm

This talk explorers one approach that utilises XML pipes. With the right infrastructure, the author was able to build a full-featured online shop totally in XSLT. This new architecture will be contrasted against a traditional 3-tier architecture. A quick implementation walk through will also be given.

Building Web Services with Microsoft WSE

Date: Wednesday, 7th July 2004
Presenter: Dr. Jim Webber (Senior researcher from the University of Newcastle upon Tyne)

This talk will introduce the latest architectural advances in Web Services, and highlight the move towards a message-passing model for Web Services applications. Following on from this the talk will explore the features of Microsoft's WSE (Web Services Enhancements for .Net) 2.0 that can be used to build applications according to this new paradigm. In particular we will cover the various messaging APIs that WSE 2.0 supports and show how Web Services can be decoupled from the Web by using transports other than HTTP to transfer SOAP messages between Web Services. We will also dicuss the security and policy features supported by WSE 2.0 and show how these can be employed to build secure applications. All of these features will be discussed both at the conceptual level and in code, culminating in a fully functional Web Services-based application.

XML query processing and optimization

Date: Wednesday, 2nd June 2004
Presenter: Dr. Wei Wang (Lecturer School of Computer Science and Engineering UNSW)

In this talk, we will first introduce the state-of-the-art research results related to XML query processing and optimization. Then we will discuss in more details several special topics, for example, XML encoding, XML indexing and join processing.

Web Services - a Microsoft Update

Date: Wednesday, 5th May 2004
Presenter: Anna Liu (Architect Advisor at Microsoft Australia)

Anna's presentation included answers to the following questions:

What is the relationship between Web Services and Service Oriented Architecture?

Where does Web Services fit in the software development landscape?

What is Microsoft doing in the Web Services area?

How will future Web Services based technologies potentially shift programming paradigm?

Implementing an Asynchronous Web Service

Date: Wednesday, 7th April 2004
Presenters: Bill Donoghoe and Dr Hao He

The implementation of an asynchronous Web Service will be explained and demonstrated.

This demonstration will highlight how a Web Service can be implemented to perform a operation that cannot return an instantaneous result.

An Introduction to RESTfull Web Services

Date: Wednesday, 4th February 2004
Presenter: Bill Donoghoe

A short introduction on Web Services within the context of the Architecture of the World Wide Web. This talk attempted to provide useful definitions for a few Web Services related acronyms, including SOA, REST, WSDL, UDDI and SOAP.
