Novel Approaches To Image Segmentation Based On Neutrosophic Logic, Ming Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Neutrosophy studies the origin, nature, scope of neutralities, and their interactions with different ideational spectra. It is a new philosophy that extends fuzzy logic and is the basis of neutrosophic logic, neutrosophic probability, neutrosophic set theory, and neutrosophic statistics.

Because the world is full of indeterminacy, the imperfection of knowledge that a human receives/observes from the external world also causes imprecision. Neutrosophy introduces a new concept , which is the representation of indeterminacy. However, this theory is mostly discussed in physiology and mathematics. Thus, applications to prove this theory can solve real problems are needed.

Image segmentation is the first …

An Evolutionary Approach To Optimization Of Compound Stock Trading Indicators Used To Confirm Buy Signals, Allan W. Teeples

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examines the application of genetic algorithms to the optimization of a composite set of technical indicator filters to confirm or reject buy signals in stock trading, based on probabilistic values derived from historical data. The simplicity of the design, which gives each filter within the composite filter the ability to act independently of the other filters, is outlined, and the cumulative indirect effect each filter has on all the others is discussed. This system is contrasted with the complexity of systems from previous research that attempt to merge several indicator filters together by giving each one a weight …

Xpath-Based Template Language For Describing The Placement Of Metadata Within A Document, Vijay Kumar Musham

Computer Science Theses & Dissertations

In the recent years, there has been a tremendous growth in Internet and online resources that had previously been restricted to paper archives. OCR (Optical Character Recognition) tools can be used for digitalizing an existing corpus and making it available online. A number of federal agencies, universities, laboratories, and companies are placing their collections online and making them searchable via metadata fields such as author, title, and publishing organization. Manually creating metadata for a large collection is an extremely time-consuming task, and is difficult to automate, particularly for collections consisting of documents with diverse layout and structure. The Extract project …

Terrain Impostors, William Hamilton Hess

Master's Theses

Interactive software applications which need to render large terrain meshes can suffer from slow frame rates if the geometry of the terrain is sufficiently dense. However, the viewing angle to many distant features of the terrain does not change rapidly with respect to time. If the movement of the viewing position is limited to continuous motion and restrained to a known speed, many terrain features may be rendered once in high detail and reused for several frames.

This thesis proposes a method to increase the rendering speed of large complex terrains by splitting the terrain into contiguous chunks. If a …

“Make A Bomb In Your Mums Kitchen”: Cyber Recruiting And Socialisation Of ‘White Moors’ And Home Grown Jihadists, Robyn Torok

Australian Counter Terrorism Conference

As a consequence of the war on terror, al-Qaeda and associated jihad groups have evolved and made increasing use of internet technologies for cyber recruitment. Recently, there has been an increasing focus on recruiting home grown terrorists who can more easily escape the scrutiny of cross border entries. Case study analysis indicates that links do exist between cyber tools, radicalisation and terrorism, however, the strength and nature of these relationships is generally unclear. Evidence does seem to support that cyber tools are most significant in the initial phases of recruitment and radicalisation. Coupled with this is the strong evolution of …

Home Computer Security Can Be Improved Using Online Video Streaming Services, Russell Barber

Regis University Student Publications (comprehensive collection)

Home computer users face many new computer security threats. The rise of the internet has enabled viruses to spread rapidly.

New Approaches To Mitigation Of Malicious Traffic In Voip Networks, Tobi Wulff, Ray Hunt

Australian Information Security Management Conference

Voice over IP (VoIP) telephony is becoming widespread in use, and is often integrated into computer networks. Because of this, malicious software threatens VoIP systems in the same way that traditional computer systems have been attacked by viruses, worms, and other automated agents. VoIP networks are a challenge to secure against such malware as much of the network intelligence is focused on the edge devices and access environment. This paper describes the design and implementation of a novel VoIP security architecture in which evaluation of, and mitigation against, malicious traffic is demonstrated by the use of virtual machines to emulate …

Chemical Plume Tracing By Discrete Fourier Analysis And Particle Swarm Optimization, Eugene Jun Jie Neo, Eldin Wee Chuan Lim

Australian Security and Intelligence Conference

A novel methodology for solving the chemical plume tracing problem that utilizes data from a network of stationary sensors has been developed in this study. During a toxic chemical release and dispersion incident, the imperative need of first responders is to determine the physical location of the source of chemical release in the shortest possible time. However, the chemical plume that develops from the source of release may evolve into a highly complex distribution over the entire contaminated region, making chemical plume tracing one of the most challenging problems known to date. In this study, the discrete Fourier series method …

Criminal Intelligence Career Development – Supporting The Case For Integration And Inclusion, Wayne Snell

Australian Security and Intelligence Conference

The implementation of a developmental continuum for intelligence professionals, based on a traditional competency model may be ubiquitous across the breadth of intelligence. This paper argues that specialised contextual and cultural education and training and subsequent recognition of those skills, knowledge and attributes, is an essential element in achieving organisational and individual objectives for criminal intelligence professionals. The full integration of criminal intelligence operations into police and law enforcement decision making at the tactical, operational and strategic levels is an aspirational step in achieving a multidisciplinary operational environment. The delineation of intelligence practitioners based on employment status, facilitated by the …

A Comparison Of Laboratory And Vulnerability Evaluation Methods For The Testing Security Equipment, Benjamin Beard, David J. Brooks

Australian Security and Intelligence Conference

A facility wide security system cannot be tested without causing disruption or creating vulnerabilities within the system. To overcome this issue, individual components or equipment may be evaluated to a priori performance standard. The two common approaches to security equipment evaluations are vulnerability attacks and laboratory testing. Laboratory testing of security equipment can reduce the costs and time associated with evaluations, as well as limiting the subjectivity of the tests. Vulnerability attacks will produce more realistic evaluation results of the whole security system; nevertheless, the data obtained is dependent on the physical attributes and skill of the attackers. This study …

Organisational Resilience: A Propositional Study To Understand And Identify The Essential Concepts, Bruce Braes, David Brooks

Australian Security and Intelligence Conference

Increased exposure to turmoil has raised business, social and governmental concerns over the ability of organisations to anticipate and respond positively to disruptions. Organisations are spending increased sums of money to raise levels of security; however, Organisational Resilience is a vague, multidisciplined and diverse philosophy, requiring a multiplicity of skills and knowledge that reaches far beyond security alone. The resilience domain is still developing and expanding; however, early embodiments of Organisational Resilience, originating in the United Kingdom and the United States, were nothing more than a rebranding of business continuity management strategies, put together as a ‘resilience processes’, or ‘resilience …

Assessing Vulnerabilities Of Biometric Readers Using An Applied Defeat Evaluation Methodology, David Brooks

Australian Security and Intelligence Conference

Access control systems using biometric identification readers are becoming common within critical infrastructure and other high security applications. There is a perception that biometric, due to their ability to identify and validate the user, are more secure. However, biometric systems are vulnerable to many categories of attack vectors and there has been restricted research into such defeat vulnerabilities. This study expands on a past article (Brooks, 2009) that presented a defeat evaluation methodology applied to high-security biometric readers. The defeat methodology is represented, but applied to both fingerprint and back-of-hand biometric readers. Defeat evaluation included both physical and technical integrity …

National Security: A Propositional Study To Develop Resilience Indicators As An Aid To Personnel Vetting, David Brooks, Jeff Corkill, Julie-Ann Pooley, Lynne Cohen, Cath Ferguson, Craig Harmes

Australian Security and Intelligence Conference

Within the National Security domain there is a convergence of security responsibility across the national security agencies, law enforcement and private security sectors. The sensitivity of this environment requires individuals operating in the domain to be honest, trustworthy and loyal. Personnel vetting is a formal process used to determine an individual’s suitability for access to this domain. Notwithstanding this process, significant breaches of trust, security, and corruption still occur. In psychology, resilience is a well researched phenomenon that is considered a multidimensional construct where individual attributes, family aspects and social environment interact in aiding individuals to deal with vulnerability. There …

Terrorism In Australia: A Psychometric Study Into The Western Australian Public Perception Of Terrorism, Richard Sargent, David J. Brooks

Australian Security and Intelligence Conference

Terrorism is not a new concept, as historically terrorist organisations have used the threat of violence or actual violence to generate fear in individuals, organisations and governments alike. Fear is a weapon and is used to gain political, ideological or religious objectives. Past terrorist attacks have raised concerns around the world, as governments ensured that their anti-terrorism security strategies are adequate. Domestically, Australia upgraded its capacity to respond to terrorism events through security enhancements across many areas and with new initiatives such as the 2002 public counter terrorism campaign. Nevertheless, there has been restricted research into how terrorist events have …

Australian Critical Infrastructure Protection: A Case Of Two Tales, Matthew Warren, Graeme Pye, William Hutchinson

Australian Information Warfare and Security Conference

The protection of critical infrastructures and the choices made in terms of priorities and cost, all impact upon the planning, precautions and security aspects of protecting these important systems. Often the when choices made is difficult to assess at the time the decision is taken and it is only after an incident that the truth of the choices made become fully evident. The paper focuses on two recent examples of Australian Critical Infrastructure protection and the issues that related to those examples.

Influence Operations: Action And Attitude, William Hutchinson

Australian Information Warfare and Security Conference

This paper investigates the relationships between attitudes, behaviour and influence. The major objective of influence operations is predominantly to exert soft power and in doing this there is an assumption that it will change attitudes. It is assumed that by changing attitudes favourable to the influencer that behaviours will be changed. However, this is a problematic assumption. Influence operations whose messages seem to contradict the real behaviour of the influencer tends to nullify the message; and, in fact, might reinforce the attitudes and behaviours of the foe and begin to alienate friends. Messages should be based on a credible reality; …

Threat Modelling With Stride And Uml, Michael N. Johnstone

Australian Information Security Management Conference

Threat modelling as part of risk analysis is seen as an essential part of secure systems development. Microsoft’s Security Development Lifecycle (SDL) is a well-known software development method that places security at the forefront of product initiation, design and implementation. As part of SDL, threat modelling produces data flow diagrams (DFDs) as key artefacts and uses those diagrams as mappings with STRIDE to identify threats. This paper uses a standard case study to illustrate the effects of using an alternative process model (UML activity diagrams) with STRIDE and suggests that using a more modern process diagram can generate a more …

Australian Information Security Management Conference

The objective of this paper is to provide a managed always best connected service to mobile entities over underlying heterogeneous wireless and mobile platforms while maintaining negotiated security and quality of service (QoS). This paper proposes a new model and its architecture which is based upon Policy-based Management but provides a new framework based on layered-approach for the centralised management of mobile clients. In particular, we propose and implement a new model of a policy-managed mobile client and its architecture to support seamless handoff across multiple access networks. The proposed mobile client supports multi-domain authentication, authorisation and security based on …

Micro-Blogging In The Workplace, Chia Yao Lee, Matthew Warren

Australian Information Security Management Conference

Micro-blogging services such as Twitter, Yammer, Plurk and Google Buzz have generated substantial interest among members of the business community in recent years. Many CEOs, managers and front-line employees have embraced micro-blogs as a tool for interacting with colleagues, employees, customers, suppliers and investors. Micro-blogs are considered a more informal channel than emails and official websites, and thus present a different set of challenges to businesses. As a positional paper, this paper uses a case study of a bogus Twitter account to emphasise security and ethical issues relating to (i) Trust, Accuracy and Authenticity of Information, (ii) Privacy and Confidentiality, …

A Novel Design And Implementation Of Dos-Resistant Authentication And Seamless Handoff Scheme For Enterprise Wlans, Isaac Lee, Ray Hunt

Australian Information Security Management Conference

With the advance of wireless access technologies, the IEEE 802.11 wireless local area network (WLAN) has gained significant increase in popularity and deployment due to the substantially improved transmission rate and decreased deployment costs. However, this same widespread deployment makes WLANs an attractive target for network attacks. Several vulnerabilities have been identified and reported regarding the security of the current 802.11 standards. To address those security weaknesses, IEEE standard committees proposed the 802.11i amendment to enhance WLAN security. The 802.11i standard has demonstrated the capability of providing satisfactory mutual authentication, better data confidentiality, and key management support, however, the design …

An Information Security Governance Framework For Australian Primary Care Health Providers, Donald C. Mcdermid, Rachel J. Mahncke, Patricia A H Williams

Australian Information Security Management Conference

The competitive nature of business and society means that the protection of information, and governance of the information security function, is increasingly important. This paper introduces the notion of a governance framework for information security for health providers. It refines the idea of an IT Balanced Scorecard into a scorecard process for use in governing information security for primary care health providers, where IT and security skills may be limited. The approach amends and justifies the four main elements of the scorecard process. The existence of a governance framework specifically tailored for the needs of primary care practice is a …

Information Leakage Through Online Social Networking: Opening The Doorway For Advanced Persistence Threats, Nurul Nuha Abdul Molok, Shanton Chang, Atif Ahmad

Australian Information Security Management Conference

The explosion of online social networking (OSN) in recent years has caused damages to organisations due to leakage of information by their employees. Employees’ social networking behaviour, whether accidental or intentional, provides an opportunity for advanced persistent threats (APT) attackers to realise their social engineering techniques and undetectable zero-day exploits. APT attackers use a spear-phishing method that targeted on key employees of victim organisations through social media in order to conduct reconnaissance and theft of confidential proprietary information. This conceptual paper posits OSN as the most challenging channel of information leakage and provides an explanation about the underlying factors of …

Defining The Security Professional: Definition Through A Body Of Knowledge, Mel Griffiths, David J. Brooks, Jeffrey Corkill

Australian Security and Intelligence Conference

A subject that eludes a consensus definition, security is an amalgam of disciplines that is moving inexorably towards professionalisation. Yet identifying who or what defines a security professional remains as difficult and elusory as a comprehensive definition of security that captures all of its modern facets and many actors. The view of elevating such a discipline as security to the status of a profession provokes polarised opinions. This article reviews the literature, examining what elements identify a security professional and exploring the significant themes and issues. To support these elements, security experts (n=27) were surveyed using a multidimensional scaling technique …

Development And Evaluation Of A Secure Web Gateway Using Existing Icap Open Source Tools, Michael Pearce, Ray Hunt

Australian Information Security Management Conference

This work in progress paper discusses the development and evaluation of an open source secure web gateway. The proof of concept system uses a combination of open source software (including the Greasyspoon ICAP Server, Squid HTTP proxy, and Clam Antivirus) to perform the various security tasks that range from simple (such as passive content insertion) to more advanced (such as active content alteration) by modules installed on the server. After discussing the makeup of the proof of concept system we discuss our evaluation methodology for both effectiveness and performance. The effectiveness was tested using comparative analysis of groups of self-browsing …

Success Of Agile Environment In Complex Projects, Abbass Ghanbary, Julian Day

Australian Information Warfare and Security Conference

This paper discusses the impact of agile methodology in complex and modular interrelated projects based on the authors’ practical experience and observations. With the advancement of Web technologies and complex computer systems, business applications are able to transcend boundaries in order to fully meet business requirements and comply with the legislation, policies and procedures. The success of software development as well as software deployment of these complex applications is dependent upon the employed methodology and project management. This is so because employed methodology plays an important position in capturing and modeling of business requirements and project management helps to ensure …

An Analytical Study Of It Security Governance And Its Adoption On Australian Organisations, Tanveer A. Zia

Australian Information Security Management Conference

Contemporary organisations are at infancy stages of adopting IT governance processes in Australia. Organisations who have adopted these processes underestimate the security processes within the governance framework. If the security processes are designed, they are often flawed with operational level implementation. This study investigates IT security governance broadly and in Australian organisations specifically. The objective of this study is to bring the local organisations in alignment with international standards and frameworks in terms of integration of information security, IT audits, risks and control measures. A survey of selected organisations is completed and results are presented in this paper identifying the …

Security Information Supplied By Australian Internet Service Providers, Patryk Szewczyk

Australian Information Security Management Conference

Results from previous studies indicate that numerous Internet Service Providers within Australia either have inadequately trained staff, or refuse to provide security support to end-users. This paper examines the security information supplied by Internet Service Providers on their website. Specifically content relating to securing; a wireless network, an ADSL router, and a Microsoft Windows based workstation. A further examination looked at the accuracy, currency, and accessibility of information provided. Results indicate that the information supplied by Internet Service Providers is either inadequate or may in fact further deter the end-user from appropriately securing their computer and networking devices.

The Economics Of Developing Security Embedded Software, Craig S. Wright, Tanveer A. Zia

Australian Information Security Management Conference

Market models for software vulnerabilities have been disparaged in the past citing how these do little to lower the risk of insecure software. In this paper we argue that the market models proposed are flawed and not the concept of a market itself. A well-defined software risk derivative market would improve the information exchange for both the software user and vendor removing the often touted imperfect information state that is said to believe the software industry. In this way, users could have a rational means of accurately judging software risks and costs and as such the vendor could optimally apply …
