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

Understanding Transition Towards Information Security Culture Change, Leanne Ngo, Wanlei Zhou, Matthew Warren
Research outputs pre 2011
Transitioning towards an information security culture for organisations has not been adequately explored in the current security and management literature. Many authors have proposed how information security culture can be created, fostered and managed within organisations, but have failed to adequately address the transition process towards information security culture change, particularly for small medium enterprises (SMEs). This paper aims to (1) recapitulate key developments and trends within information security culture literature; (2) explore in detail the transition process towards organisational change; (3) adapt the transition process with respects to the key players involved in transition and propose a transition model …

Analysis Of Channel Estimation Error Of Ofdm Systems In Rayleigh Fading, Bin Jiao, Jitian Xiao, Jinlin Wang
Analysis Of Channel Estimation Error Of Ofdm Systems In Rayleigh Fading, Bin Jiao, Jitian Xiao, Jinlin Wang
Research outputs pre 2011
In wireless OFDM applications, since the radio channel is frequency selective and time-varying, a dynamic estimation of channel must be achieved before the demodulation of the transmitted OFDM signals. As an effective approach for solving the channel estimation problems, the pilot-assisted channel estimation technique has received considerable attention in recent years. In this paper, we investigate the channel estimation error in the existing pilot-assisted channel estimation approaches in detail, a new effective channel estimation approach with lower estimation error is proposed as well.

This paper details the development and implementation of a module of online curriculum developed for Year Eleven Food Technology (sixteen years of age) students. The module was developed using a framework (CLEO - Curriculum Learning and Education Online) that embeds learning technologies, utilises industry partnerships, has cross curriculum outcomes, scaffolds information literacy skills development and was the …
A Bipartite Graph Approach To Generate Optimal Test Sequences For Protocol Conformance Testing Using The Wp-Method, Jun Wang, Jitian Xiao, Chiou Peng Lam, Huaizhong Li
A Bipartite Graph Approach To Generate Optimal Test Sequences For Protocol Conformance Testing Using The Wp-Method, Jun Wang, Jitian Xiao, Chiou Peng Lam, Huaizhong Li
Research outputs pre 2011
Conformance testing using test sequences is used to ensure that a protocol implementation conforms to its specification. A commonly used technique to generate test sequences for specifications described by the finite state machines is the Wp-method with the Reset technique, which frequently results in long test sequences. In this paper, we propose a bipartite graph approach to generate optimal test sequences for protocol conformance testing. Our approach significantly reduces the length of the test sequences required for conformance testing while maintaining the same fault detection capability.
Enumerating Knight's Tours Using An Ant Colony Algorithm, Philip Hingston, Graham Kendall
Enumerating Knight's Tours Using An Ant Colony Algorithm, Philip Hingston, Graham Kendall
Research outputs pre 2011
In this paper, we show how an ant colony optimisation algorithm may be used to enumerate knight's tours for variously sized chessboards. We have used the algorithm to enumerate all tours on 5×5 and 6×6 boards, and, while the number of tours on an 8×8 board is too large for a full enumeration, our experiments suggest that the algorithm is able to uniformly sample tours at a constant, fast rate for as long as is desired.

Blackhat Fingerprinting Of The Wired And Wireless Honeynet, Suen Yek
Blackhat Fingerprinting Of The Wired And Wireless Honeynet, Suen Yek
Research outputs pre 2011
TCP/IP fingerprinting is a common technique used to detect unique network stack characteristics of an Operating System (OS) . Its usage for network compromise is renowned for performing host discovery and in aiding the blackhat to determine a tailored exploit of detected OSs. The honeyd honeynet is able to countermeasure blackhats utilising TCP/IP fingerprinting via host device emulation on a virtual network. Honeyd allows the creation of host personalities that respond to network stack fingerprinting as a real network would. The nature of this technique however, has shown to provide inconsistent and unreliable results when performed over wired and wireless …

Instant messenger programs such as ICQ are often used by hackers and criminals for illicit purposes and consequently the logfiles from such programs are of forensic interest. This paper outlines research in progress that has resulted in the development of a tool for the extraction of ICQ logfile entries. Detailed reconstruction of data from logfiles was achieved with a number of different ICQ software, with other programs still to be tested. There are several limitations including timestamp information not adjusted for the time zone, data could be altered, and conversations must be manually reconstructed. Future research will aim to address …
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. Such a policy must address both the size and nature of the enterprise, and the resources available to it. Measures such as WEP and MAC filtering are only appropriate for home …

Architecture For Self-Estimation Of Security Level In Ad Hoc Network Nodes, Reijo Savola
Architecture For Self-Estimation Of Security Level In Ad Hoc Network Nodes, Reijo Savola
Research outputs pre 2011
Inherent freedom due to a lack of central authority of self-organised mobile ad hoc networks introduces challenges to security and trust management. In these kinds of scenarios, the nodes themselves are naturally responsible for their own security – or they could trust certain known nodes, called “micro-operators”. We propose an architecture for security management in self-organising mobile ad hoc networks that is based on the nodes’ own responsibility and node-level security monitoring. The aim is to predict, as well as to monitor the security level concentrating on the principal effects contributing to it.

Information Security: A Misnomer, William Hutchinson
Information Security: A Misnomer, William Hutchinson
Research outputs pre 2011
This paper argues that the definition of 'information' is crucial to the understanding of 'information security'. At present, information security concentrates on the technological aspects of data, computer and network security. This computer-centric approach ignores the fact that the majority of information within an organisation is derived from other sources than computer stored data. The implications for security are that much data can be leaked from an organisation even if the computer and network systems are secured.

Ad2us: An Automated Approach To Generating Usage Scenarios From Uml Activity Diagrams, Robert Chandler, Chiou Peng Lam, Huaizhong Li
Research outputs pre 2011
Although attention has been given to the use of UML (Unified Modelling Language) activity diagrams in the generation of scenarios, thin-threads and test-cases, the processes described in the literature rely heavily on manual intervention either in the information extraction process or in the process of transforming them to an alternate structure. This paper introduces an approach that capture, store and output usage scenarios derived automatically from UML activity diagrams.

Using In-Depth Interviewing To Evaluate Deep Learning In Students Who Use Online Curriculum: A Literature Review, Maria Woodhouse
Research outputs pre 2011
There are numerous difficulties associated with evaluating student experience of online curriculum, not least of which is the fact that different research methods elicit different types of information. The usefulness of choosing either quantitative or qualitative methods depends on their power to bear upon the research questions. This concept paper presents the learning experience as a qualitative event and argues that the in-depth interview is an apt tool for discovering to what extent students experience deep-learning in studying online subjects. To this end, this concept paper will consider the literature surrounding the in-depth interview as a research method. It will …
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
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 …
How To Build A Faraday On The Cheap For Wireless Security Testing, Suen Yek
How To Build A Faraday On The Cheap For Wireless Security Testing, Suen Yek
Research outputs pre 2011
The commonly known security weaknesses associated with the 802.11b wireless standard have introduced a variety of security measures to countermeasure attacks. Using a wireless honeypot, a fake wireless network may be configured through emulation of devices and the TCP/IP fingerprinting of OS network stacks. TCP/IP fingerprinting is one of the most popular methods employed to determine the type of OS running on a target and this information can then be used to determine the type of vulnerabilities to target on the host. Testing the effectiveness of this technique to ensure that a wireless honeypot using honeyd may deceive an attacker …

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 …

Designing Comminution Circuits With A Multi-Objective Evolutionary Algorithm, Simon Huband, Luigi Barone, Philip Hingston, Lyndon While, David Tuppurainen, Richard Bearman
Research outputs pre 2011
Mining is an important industry in Australia, contributing billions of dollars to the economy. The performance of a processing plant has a large impact on the profitability of a mining operation, yet plant design decisions are typically guided more by intuition and experience than by analysis. In this paper, we motivate the use of an evolutionary algorithm to aid in the design of such plants. We formalise plant design in terms suitable for application in a multi-objective evolutionary algorithm and create a simulation to assess the performance of candidate solutions. Results show the effectiveness of this approach with our algorithm …
Detecting Rogue Access Points That Endanger The Maginot Line Of Wireless Authentication, Zhiqi Tao, A. B. Ruighaver
Detecting Rogue Access Points That Endanger The Maginot Line Of Wireless Authentication, Zhiqi Tao, A. B. Ruighaver
Research outputs pre 2011
The rapid growth in deployment of wireless networks in recent years may be an indication that many organizations believe that their system will be adequately secured by the implementation of enhanced encryption and authentication. However, in our view, the emphasis on cryptographic solutions in wireless security is repeating the history of the “Maginot Line”. Potential attackers of wireless networks currently will find many ways to get access to wireless networks to compromise the confidentiality of information without the need to crack the encryption. In this paper we analyze how rogue access points threaten the security of an organization’s wireless network …

Integrating Open Source Protections Into Scada Networks, Craig Valli
Research outputs pre 2011
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 …

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 …
