Managing Wireless Security Risks In Medical Services, Brian Cusack, Akar Kyaw
Australian eHealth Informatics and Security Conference
Medical systems are designed for a range of end users from different professional skill groups and people who carry the devices in and on their bodies. Open, accurate, and efficient communication is the priority for medical systems and consequently strong protection costs are traded against the utility benefits for open systems. In this paper we assess the vulnerabilities created by the professional and end user expectations, and theorise ways to mitigate wireless security vulnerabilities. The benefits of wireless medical services are great in terms of efficiencies, mobility, and information management. These benefits may be realised by treating the vulnerabilities and …
Towards A Set Of Metrics To Guide The Generation Of Fake Computer File Systems, Ben Whitham
Towards A Set Of Metrics To Guide The Generation Of Fake Computer File Systems, Ben Whitham
Australian Digital Forensics Conference
Fake file systems are used in the field of cyber deception to bait intruders and fool forensic investigators. File system researchers also frequently generate their own synthetic document repositories, due to data privacy and copyright concerns associated with experimenting on real-world corpora. For both these fields, realism is critical. Unfortunately, after creating a set of files and folders, there are no current testing standards that can be applied to validate their authenticity, or conversely, reliably automate their detection. This paper reviews the previous 30 years of file system surveys on real world corpora, to identify a set of discrete measures …

Forensic Examination And Analysis Of The Prefetch Files On The Banking Trojan Malware Incidents, Andri P. Heriyanto
Forensic Examination And Analysis Of The Prefetch Files On The Banking Trojan Malware Incidents, Andri P. Heriyanto
Australian Digital Forensics Conference
Whenever a program runs within the operating system, there will be data or artefacts created on the system. This condition applies to the malicious software (malware). Although they intend to obscure their presence on the system with anti-forensic techniques, still they have to run on the victim’s system to acquire their objective. Modern malware creates a significant challenge to the digital forensic community since they are being designed to leave limited traces and misdirect the examiner. Therefore, every examiner should consider performing all the forensics approaches such as memory forensic, live-response and Windows file analysis in the related malware incidents …

The Bad Guys Are Using It, Are You?, Hong-Eng Koh
Australian Security and Intelligence Conference
From Occupy Wall Street to 2011 England riots to Arab Spring to Mumbai 26/11 to the ethnic cleansing rumors in India and increasingly used by pedophiles, social media is a very powerful tool for pedophiles, troublemakers, criminals and even terrorists to target individuals and even to go against the establishment. On the other hand, social media can save lives in a disaster, and its a natural extension of community policing or engagement. Community engagement is a must-have strategy for any public safety and security agency. However, this strategy requires the removal of stovepipe processes and systems within an agency, allowing …

Listening To Botnet Communication Channels To Protect Information Systems, Brian Cusack, Sultan Almutairi
Australian Digital Forensics Conference
Botnets are a weapon of choice for people who wish to exploit information systems for economic advantage. A large percentage of high value commercial targets such as banking transaction systems and human customers are web connected so that access is gained through Internet services. A Botnet is designed to maximise the possibility of an economic success through the low cost of attacks and the high number that may be attempted in any small time unit. In this paper we report exploratory research into the communications of Botnets. The research question was: How do Botnets talk with the command and control …

The Zombies Strike Back: Towards Client-Side Beef Detection, Maxim Chernyshev, Peter Hannay
Australian Digital Forensics Conference
A web browser is an application that comes bundled with every consumer operating system, including both desktop and mobile platforms. A modern web browser is complex software that has access to system-level features, includes various plugins and requires the availability of an Internet connection. Like any multifaceted software products, web browsers are prone to numerous vulnerabilities. Exploitation of these vulnerabilities can result in destructive consequences ranging from identity theft to network infrastructure damage. BeEF, the Browser Exploitation Framework, allows taking advantage of these vulnerabilities to launch a diverse range of readily available attacks from within the browser context. Existing defensive …

A Forensically-Enabled Iaas Cloud Computing Architecture, Saad Alqahtany, Nathan Clarke, Steven Furnell, Christoph Reich
Australian Digital Forensics Conference
Current cloud architectures do not support digital forensic investigators, nor comply with today’s digital forensics procedures largely due to the dynamic nature of the cloud. Whilst much research has focused upon identifying the problems that are introduced with a cloud-based system, to date there is a significant lack of research on adapting current digital forensic tools and techniques to a cloud environment. Data acquisition is the first and most important process within digital forensics – to ensure data integrity and admissibility. However, access to data and the control of resources in the cloud is still very much provider-dependent and complicated …
Up-Dating Investigation Models For Smart Phone Procedures, Brian Cusack, Raymond Lutui
Up-Dating Investigation Models For Smart Phone Procedures, Brian Cusack, Raymond Lutui
Australian Digital Forensics Conference
The convergence of services in Smart Technologies such as iPhones, Androids and multiple tablet work surfaces challenges the scope of any forensic investigation to include cloud environments, devices and service media. The analysis of current investigation guidelines suggests that each element in an investigation requires an independent procedure to assure the preservation of evidence. However we dispute this view and review the possibility of consolidating current investigation guidelines into a unified best practice guideline. This exploratory research proposes to fill a gap in digital forensic investigation knowledge for smart technologies used in business environments and to propose a better way …

The Impact Of Custom Rom Backups On Android External Storage Erasure, Haydon Hope, Peter Hannay
Australian Digital Forensics Conference
The Android operating system is the current market leader on mobile devices such as smartphones and tablet computers. The core operating system is open source and has a number of developers creating variants of this operating system. These variants, often referred to as custom ROMs are available for a wide number of mobile devices. Custom ROMs provide a number of features, such as enhanced control over the operating system, variation in user interfaces and so on. The process of installing custom ROMs is often accomplished through the use of a ROM manager application. Such applications often provide mechanisms to back …
Rapid Forensic Crime Scene Analysis Using Inexpensive Sensors, Dan Blackman
Rapid Forensic Crime Scene Analysis Using Inexpensive Sensors, Dan Blackman
Australian Digital Forensics Conference
Network forensics and Network Intrusion Detection Systems (NIDS) have ultimately become so important to corporations that in many cases they have been relied upon to identify the actions of offenders and to provide sufficient details to prosecute them. Unfortunately, as data links on corporate networks have increased to saturation, more information is being missed and even though corporations have spent heavily acquiring loud, power hungry devices to monitor their networks. A more power efficient solution, which consumes less electricity, yet provides the same or better packet inspection is an obvious solution.. This paper discusses a possible solution using a cluster …

Evaluating The Security Vulenerabilities Of The Ip6to4 Tunnelling Mechanism, Brian Cusack, Raymond Lutui
Evaluating The Security Vulenerabilities Of The Ip6to4 Tunnelling Mechanism, Brian Cusack, Raymond Lutui
Australian Information Security Management Conference
The two versions of Internet Protocol (IP) rely on mechanisms that will convert one protocol to the other and vice versa. Version 4 is still prevalent in the Internet backbone and version 6 in most private networks. In this research we focus on the automatic tunnelling mechanism that provides the encapsulation at one end of the transition tunnel and the de-encapsulation at the other end dependant on the direction of transition. In our research we asked: How secure is the automatic tunnelling mechanism? It is a simple question but important given the number of times transition may occur in any …
Attribute-Based Encryption With Encryption And Decryption Outsourcing, Muhammad Asim, Milan Petkovic, Tanya Ignatenko
Attribute-Based Encryption With Encryption And Decryption Outsourcing, Muhammad Asim, Milan Petkovic, Tanya Ignatenko
Australian Information Security Management Conference
In this paper we propose a new scheme for ciphertext-policy attribute-based encryption that allows outsourcing of computationally expensive encryption and decryption steps. The scheme constitutes an important building block for mobile applications where both the host and users use mobile devices with limited computational power. In the proposed scheme, during encryption the host involves a semi-trusted proxy to encrypt a partially encrypted (by the host) message according to an access policy provided by the host. The proxy is unable to learn the message from this partially encrypted text. A user can only decrypt the stored ciphertext if he possesses secret …
Securing Identity Information With Image Watermarks, Brian Cusack, Reza Khaleghparas
Securing Identity Information With Image Watermarks, Brian Cusack, Reza Khaleghparas
Australian Information Security Management Conference
In this paper, we describe the requirements for embedding watermarks in images used for identity verification and demonstrate a proof of concept in security sciences. The watermarking application is designed for verifying the rightful ownership of a driving license or similar identity object. The tool we built and tested embeds and extracts watermarks that contain verification information of the rightful owner. We used the human finger print of the rightful owner as the watermark. Such information protection mechanisms add an extra layer of security to the information system and improve verification of identification attributes by providing strong security. The issues …
An Analysis Of Security Issues In Building Automation Systems, Matthew Peacock, Michael N. Johnstone
An Analysis Of Security Issues In Building Automation Systems, Matthew Peacock, Michael N. Johnstone
Australian Information Security Management Conference
The purpose of Building Automation Systems (BAS) is to centralise the management of a wide range of building services, through the use of integrated protocol and communication media. Through the use of IP-based communication and encapsulated protocols, BAS are increasingly being connected to corporate networks and also being remotely accessed for management purposes, both for convenience and emergency purposes. These protocols, however, were not designed with security as a primary requirement, thus the majority of systems operate with sub-standard or non-existent security implementations, relying on security through obscurity. Research has been undertaken into addressing the shortfalls of security implementations in …

Persistent Issues In Encryption Software: A Heuristic And Cognitive Walkthrough, Jad El-Abed, Patryk Szewczyk
Australian Information Security Management Conference
The support information accompanying security software can be difficult to understand by end-users, who have little knowledge in cyber security. One mechanism for ensuring the integrity and confidentiality of information is encryption software. Unfortunately, software usability issues can hinder an end-user’s capability to properly utilise the security features effectively. To date there has been little research in investigating the usability of encryption software and proposing solutions for improving them. This research paper analysed the usability of encryption software targeting end-users. The research identified several issues that could impede the ability of a novice end-user to adequately utilise the encryption software. …

Hybrid Intelligent Model For Software Maintenance Prediction, Abdulrahman Ahmed Bobakr Baqais, Mohammad Alshayeb, Zubair A. Baig
Research outputs 2014 to 2021
Maintenance is an important activity in the software life cycle. No software product can do without undergoing the process of maintenance. Estimating a software’s maintainability effort and cost is not an easy task considering the various factors that influence the proposed measurement. Hence, Artificial Intelligence (AI) techniques have been used extensively to find optimized and more accurate maintenance estimations. In this paper, we propose an Evolutionary Neural Network (NN) model to predict software maintainability. The proposed model is based on a hybrid intelligent technique wherein a neural network is trained for prediction and a genetic algorithm (GA) implementation is used …
Improving Pre-Hospital Care At Mass Gathering Events: Applying Military Intelligence Methodology To The St John Ambulance Wa Event Health Operations, Alan James Davies
Improving Pre-Hospital Care At Mass Gathering Events: Applying Military Intelligence Methodology To The St John Ambulance Wa Event Health Operations, Alan James Davies
Theses : Honours
With the growth of the mass gathering event domain and its ever constant place within the contemporary Australian lifestyle, the number of patrons who attend these events that require medical assistance rises (Zeitz et al., 2007, p. 23; Zeitz, Zeitz, & Arbon, 2005, p. 164; Zeitz, Zeitz, & Kadow-Griffin, 2012). This increased demand and inherited risk to the event organiser, the patrons attending and the pre-hospital care or first aid provider creates a need for the investigation into enhancements to the medical care operations at these events. The provision of pre-hospital care at mass gathering events in Western Australia is …
Suitability Of Lacunarity Measure For Blind Steganalysis, Ahmed Ibrahim
Suitability Of Lacunarity Measure For Blind Steganalysis, Ahmed Ibrahim
Australian Digital Forensics Conference
Blind steganalysis performance is influenced by several factors including the features used for classification. This paper investigates the suitability of using lacunarity measure as a potential feature vectorfor blind steganalysis. Differential Box Counting (DBC) based lacunarity measure has been employed using the traditional sequential grid (SG) and a new radial strip (RS) approach. The performance of the multi-class SVM based classifier was unfortunately not what was expected. However, the findings show that both the SG and RS lacunarity produce enough discriminating features that warrant further research.

Australian Digital Forensics Conference
This paper is an investigation focusing on activities detected by three SSH honeypots that utilise Kippo honeypot software. The honeypots were located on the same /24 IPv4 network and configured as identically as possible. The honeypots used the same base software and hardware configurations. The data from the honeypots were collected during the period 17th July 2012 and 26th November 2013, a total of 497 active day periods. The analysis in this paper focuses on the techniques used to attempt to gain access to these systems by attacking entities. Although all three honeypots are have the same configuration settings and …
A Survey Of Ipv6 Address Usage In The Public Domain Name System, Clinton R. Carpene, Andrew Woodward
A Survey Of Ipv6 Address Usage In The Public Domain Name System, Clinton R. Carpene, Andrew Woodward
Australian Information Security Management Conference
The IPv6 protocol has been slowly increasing in use on the Internet. The main reason for the development of the protocol is that the address space provided by IPv4 is nearing exhaustion. The pool of addresses provided by IPv6 is 296 times larger than IPv4, and should be sufficient to provide an address for every device for the foreseeable future. Another potential advantage of this significantly large address space is the use of randomly assigned addresses as a security barrier as part of a defence in depth strategy. This research examined the addresses allocated by those implementing IPv6 to determine …
Securing The Internet Of Things Infrastructure – Standards And Techniques, Zubair A. Baig
Securing The Internet Of Things Infrastructure – Standards And Techniques, Zubair A. Baig
Australian Information Security Management Conference
The Internet of Things (IoT) infrastructure is a conglomerate of electronic devices interconnected through the Internet, with the purpose of providing prompt and effective service to end-users. Applications running on an IoT infrastructure generally handle sensitive information such as a patient’s healthcare record, the position of a logistic vehicle, or the temperature readings obtained through wireless sensor nodes deployed in a bushland. The protection of such information from unlawful disclosure, tampering or modification, as well as the unscathed presence of IoT devices, in adversarial environments, is of prime concern. In this paper, a descriptive analysis of the security of standards …
Design Requirements For Generating Deceptive Content To Protect Document Repositories, Ben Whitham
Design Requirements For Generating Deceptive Content To Protect Document Repositories, Ben Whitham
Australian Information Warfare and Security Conference
For nearly 30 years, fake digital documents have been used to identify external intruders and malicious insider threats. Unfortunately, while fake files hold potential to assist in data theft detection, there is little evidence of their application outside of niche organisations and academic institutions. The barrier to wider adoption appears to be the difficulty in constructing deceptive content. The current generation of solutions principally: (1) use unrealistic random data; (2) output heavily formatted or specialised content, that is difficult to apply to other environments; (3) require users to manually build the content, which is not scalable, or (4) employ an …
