On-Line Training For Smes: Final Report, Beth Walker, Beverley Webster, Sue Stoney

Research outputs pre 2011

This research aimed to explore the appropriateness of on-line training delivery methods for small business owner/managers.

It is widely recognised that training and education are effective ways to reduce small business failure. In Australia, small business accounts for 96 percent of Australian private sector, non-agricultural businesses and they employ 47 percent of the private sector, non-agricultural workforce. Not surprisingly then, encouraging the development of the skills of the workforce has emerged as a major priority for government policy. However, what is also recognised is that many small business owner/managers (SBOs) have limited e-competencies.

Results of this research confirmed this and …

In an increasing competitive world, marketing survival can be depended simply on timely new information on customers and market trend. One of the most important strategies in CRM (Customer Relationship Management) is to capture enough information from customers and using this information carefully [Ryals , Tinsley]. Of course security of this information is very important in CRM data management [Bryan]. Data management is a method for scheduling and controlling data saving, recovering and processing. This activity has been done continually or periodically[Bryan]. Security level of this information depends on the security policy of the organization. CRM security policy is the …

Benchmarking E-Business Security: A Model And Framework, Graeme Pye, Matthew J. Warren

Research outputs pre 2011

The dynamic nature of threats and vulnerabilities within the E-business environment can impede online functionality, compromise organisational or customer information, contravene security implementations and thereby undermine online customer confidence. To negate these problems, E-business security has to become proactive, by reviewing and continuously improving security to strengthen E-business security measures and policies. This can be achieved through benchmarking the security measures and policies utilised within the E-business, against recognised information technology (IT) and information security (IS) security standards.

My Problem Or Our Problem? Exploring The Use Of Information Sharing As A Component Of A Holistic Approach To E-Security In Response To The Growth Of ‘Malicious Targeted Attacks’, Aaron Olding, Paul Turner

Research outputs pre 2011

There is now a growing recognition amongst e-security specialists that the e-security environment faced by organisations is changing rapidly. This environment now sees a situation where maliciously targeted attacks are conducted by ‘guns for hire’ (hackers) and/or criminal organisations (Illett 2005; Keiser 2005). As a consequence, conventional organisational approaches to e-security are becoming increasingly problematic and inadequate. There is a need to raise awareness of these issues amongst organisations and to contribute to the generation of effective integrated solutions that address this emerging e-security environment without sacrificing user privacy and/or breaching user trust. This paper considers the potential role of …

Non-Repudiation In Pure Mobile Ad Hoc Network, Yi-Chi Lin, Jill Slay

Research outputs pre 2011

Within the last decade, the use of wireless technologies has become more prevalent. Wireless networks have flexible architectures with data transferred via radio waves and can be divided into two categories; infrastructure-based wireless networks and mobile ad hoc network.

The mobile ad hoc network (MANET) is an autonomous system which can be dynamically built without pre-existing infrastructure or a trusted third party (TTP). Due to these infrastructure-less and self-organized characteristics, MANET encounters different problems from infrastructure-based wired network, such as key management, power shortage, and security issues. This paper will further divide MANETs into pure ad hoc networks which do …

Throughput And Delay Optimization In Wdm Fddi Optical Network, Muhsen Aljada, Kamal Alameh, Khalid Al-Begain

Research outputs pre 2011

The rapidly growing Internet traffic are driving the demands for higher transmission capacity and higher processing speed, especially for the backbone networks. To support such bandwidth usage an optical Fiber Distributed Data Interface Wavelengtg Division Multiplexed (FDDI/WDM) network is proposed, wherein the wavelength channels are amplified using Erbium-Doped Fiber Amplifiers (EDFA's) to compensate for the losses over the optical fiber span. In this paper we investigate the network performance for both asynchronous and synchronous transmissions by measuring the amplified spontaneous emission (ASE) along the ring, the optical signal to noise ratio (OSNR) and the electrical SNR at different destinations. The …

Security Governance: Its Impact On Security Culture, K. Koh, A. B. Ruighaver, S. B. Maynard, A. Ahmad

Research outputs pre 2011

While there is an overwhelming amount of literature that recognises the need for organisations to create a security culture in order to effectively manage security, little is known about how to create a good security culture or even what constitutes a good security culture. In this paper, we report on one of two case studies performed to examine how security governance influences security culture and in particular, the sense of responsibility and ownership of security. The results indicate that although the structural and functional mechanisms in security governance are influencing factors, it is the extent of social participation that may …

Diversity In Information And Communication Technologies: The Cost Of Lost Opportunities, Susan Gail Webb

Research outputs pre 2011

The Information and Communication Technology (ICT) industry develops products that are used by many people regardless of gender, age, social status, ethnicity, or religion. Technology has had a significant impact on the way that information is produced, stored and communicated, especially in the fields that have traditionally been heavy producers of information such as libraries and education institutions. Though all types of people use technology, not all types of people are involved in the design and development of technology. Women represent just twenty percent of Australian ICT professionals. They often receive less pay than their male colleagues and are greatly …

Recommendations For Wireless Network Security Policy: An Analysis And Classification Of Current And Emerging Threats And Solutions For Different Organisations, Andrew Woodward

Research outputs pre 2011

Since their inception, 802.11 wireless networks have been plagued by a wide range of security problems. These problems relate to both data security and denial of service attacks, and there have been many solutions created by different vendors address these problems. However, the number of different types of attack, and the many possible solutions, makes it a difficult task to put in place an appropriate wireless network security policy.

The Law And Racism: Some Reflections On The Australian Experience, Laksiri Jayasuriya

Research outputs pre 2011

Racism in Australian society is not something new and surprising. For a variety of historical and socio-political reasons it has existed from the earliest days ·of colonisation, and there have been a variety of strategies tried over the years to deal with racism as a social problem. One strategy most frequently resorted to, especially in recent years, has been to use the law as a means of combating racism. Before considering the questions of law and racism, we need first to clarify what we mean by the term racism...

Heuristics For Optimising The Calculation Of Hypervolume For Multi-Objective Optimisation Problems, Lyndon While, Lucas Bradstreet, Luigi Barone, Philip Hingston

Research outputs pre 2011

The fastest known algorithm for calculating the hypervolume of a set of solutions to a multi-objective optimization problem is the HSO algorithm (hypervolume by slicing objectives). However, the performance of HSO for a given front varies a lot depending on the order in which it processes the objectives in that front. We present and evaluate two alternative heuristics that each attempt to identify a good order for processing the objectives of a given front. We show that both heuristics make a substantial difference to the performance of HSO for randomly-generated and benchmark data in 5-9 objectives, and that they both …

SCADA (Supervisory Control And Data Acquisition) networks control much of the industrialised nations production and supply complexes. Various government reports and investigations have highlighted the vulnerability of these systems. Many of these systems are on private networks which are increasingly being connected to systems that are accessible from other networks such as the Internet. There are a range of open source tools that now offer fonctionality that can be used to secure SCADA networks from intrusion or compromise. This paper explores some of the issues with current SCADA deployment trends from a network security perspective and then examines open source …

Online Learning As Information Delivery: Digital Myopia, Jan Herrington, Thomas Reeves, Ron Oliver

Research outputs pre 2011

In business and commerce, the concept of marketing myopia has been a useful tool to predict, analyze and explain the rise and fall of businesses. In this paper, we question whether the concept can also be used to predict the ultimate downfall of online learning in higher education, if universities continue to confuse their key mission— education—with the much more product-oriented aim of information delivery. The proliferation of information-based online courses is examined within the context of the limitations imposed by widely used course management systems, institutional impediments and other factors that encourage teachers to adopt information delivery in preference …

Seeking Information Superiority: Strategies For Business In The Commercial Application Of Information Operations, Martin Dart

Research outputs pre 2011

Information superiority is a condition that many businesses attempt to attain without truly understanding what it is, or how to get there. This paper presents an overview to help businesspeople recognize the road to information superiority, and some of the essential strategies to implement along the way. Information operations is a concept described to enable information superiority, when used with a network form of organization (as opposed to simply being networked). This paper describes information operations across their fundamental structure of intelligence, surveillance, and reconnaissance (ISR); and suggests a separation between industrial espionage and legitimate business information gathering. A model …

Physician Secure Thyself, Patricia Williams

Research outputs pre 2011

Whilst discussion rages on the issues relating to security of medical data and the reason why it is important, there is little published information on how to tackle even basic security challenges for medical practice in Australia. Research suggests an underestimation of the threats to medical data by medical practitioners, hence there is sufficient reason to promote development of tools to assist medical practice with technical issues they are unfamiliar with. This paper provides an initial dialogue on how these security issues should be addressed. Included is a framework for risk assessment and elaboration of the implementation process to make …

Similarity-Aware Web Content Management And Document Pre-Fetching, Jitian Xiao, Michael Collins

Research outputs pre 2011

Web caching is intended to reduce network traffic, server load and user-perceived retrieval latency. Web pre-fetching, which can be considered as "active" caching, builds on regular Web caching, minimizing further a Web user's access delay. To be effective, however, the pre-fetching techniques must be able to predict subsequent Web access with minimum computational overheads. This paper presents a similarity-based mechanism to support similarity-aware Web document pre-fetching between proxy caches and browsing clients. We first define a set of measures to assess similarities between Web documents, and then propose a multi-cache architecture to cache Web documents based on those similarities. A …

A Critical Exploration Of The School Context For Young Adolescents Completing Primary Education, Sasha Stumpers, Lauren Breen, Julie Ann Pooley, Lynne Cohen, Lisbeth Pike

Research outputs pre 2011

Many schools have adopted relational approaches to attend to the social context in which learning transpires. More recently however, such approaches and their supporters have been criticized for not examining the school context in its entirety and the student experience within this context. The current research sought to critically explore young adolescents' experiences within the context of their school. Fifteen year seven students in an Australian primary school were interviewed about their experiences of their school context. The data were analysed using a thematic analysis and a question-ordered matrix was constructed to aid the detection of themes and sub-themes from …

Dynamic Wavefront Generation Technology Using Optovlsi Processor, Zhenglin Wang, Kamal Alameh, Rong Zheng

Research outputs pre 2011

In this paper we present a novel approach for dynamic wavefront generatio based on reconfigurable Opto-VLSI processing. Computer algorithms are developed to generate arbitrary quadric-phse lense and lenslet array with programmable focal lenght, beam steering and lens diameter by driving the Opto-VLSI processor with different computer generated phase holograms. Proff-of-concept experimental results show that multiple spheric and aspheric lens/lenslet wavefrongs can be generated with each lens independently addressed. The measured meaximum focal length tuning range is from +80mm to infinity and the beam scanning angular range is +7mrad, which are in excellent agreement with theory. Difference spatial profiles for wavefront …
