A Framework For Forensic Reconstruction Of Spontaneous Ad Hoc Networks, Alastair Nisbet
A Framework For Forensic Reconstruction Of Spontaneous Ad Hoc Networks, Alastair Nisbet
Australian Digital Forensics Conference
Spontaneous ad hoc networks are distinguished by rapid deployment for a specific purpose, with no forward planning or pre-design in their topology. Often these networks will spring up through necessity whenever a network is required urgently but briefly. This may be in a disaster recovery setting, military uses where often the network is unplanned but the devices are pre-installed with security settings, educational networks or networks created as a one-off for a meeting such as in a business organisation. Generally, wireless networks pose problems for forensic investigators because of the open nature of the medium, but if logging procedures and …
The Challeges In Implementing Security In Spontaneous Ad Hoc Networks, Alastair Nisbet
The Challeges In Implementing Security In Spontaneous Ad Hoc Networks, Alastair Nisbet
Australian Information Security Management Conference
Mobile Ad Hoc Networks (MANETS) promise much in the ability to rapidly deploy a wireless network in a fashion where no prior planning is needed and the network can be running efficiently and with high security within minutes. Natural disaster response, military, education and business provide areas where MANETS can offer significant advantages in communication where infrastructure networks may take days to set up or may be impossible to implement. This research reviews a selection of MANET protocols to show the progression of the research and the issues that are yet to be addressed. It discusses the challenges to researchers …
Cybersecurity Vulnerabilities In Medical Devices: A Complex Environment And Multifaceted Problem, Patricia A.H. Williams, Andrew J. Woodward
Cybersecurity Vulnerabilities In Medical Devices: A Complex Environment And Multifaceted Problem, Patricia A.H. Williams, Andrew J. Woodward
Research outputs 2014 to 2021
The increased connectivity to existing computer networks has exposed medical devices to cybersecurity vulnerabilities from which they were previously shielded. For the prevention of cybersecurity incidents, it is important to recognize the complexity of the operational environment as well as to catalog the technical vulnerabilities. Cybersecurity protection is not just a technical issue; it is a richer and more intricate problem to solve. A review of the factors that contribute to such a potentially insecure environment, together with the identification of the vulnerabilities, is important for understanding why these vulnerabilities persist and what the solution space should look like. This …

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 …
Insecurity By Obscurity Continues: Are Adsl Router Manuals Putting End-Users At Risk, Kim Andersson, Patryk Szewczyk
Insecurity By Obscurity Continues: Are Adsl Router Manuals Putting End-Users At Risk, Kim Andersson, Patryk Szewczyk
Australian Information Security Management Conference
The quantity and sophistication of threats targeting ADSL routers is on a steady increase. There is a reliance on end-users to ensure that their ADSL router is secure by continually updating the firmware, using strong authentication credentials, and enabling the in-built firewall. However, to do this, the end-user must be presented with well written procedural instructions, and an explanation of why this is important. This paper examines the design quality and security content provided by vendors in ADSL router manuals. This paper reveals that the lack of security related content and poor overall design could impact on end-users’ interpretation and …
Medical Identity Theft – Not Feeling Like Yourself?, Darren Webb
Medical Identity Theft – Not Feeling Like Yourself?, Darren Webb
Australian Information Security Management Conference
Hospital and general practice healthcare providers today rely heavily on the information and communication technologies they employ to provide access to patient and associated data. The continuing migration to wireless means of data transfer has afforded system users more convenient and timely access to information via the use of 802.11 based wireless network capable devices. Through the increased digital connectivity of these internet and wireless based networks, new avenues of criminal activity such as medical identity theft have been steadily increasing as malicious individuals and organisations seek to abuse the digital ubiquity of the electronic medical record. The increased need …
An Assessment Of Threats Of The Physical And Mac Address Layers In Wimax/802.16, Krishnun Sansurooah
An Assessment Of Threats Of The Physical And Mac Address Layers In Wimax/802.16, Krishnun Sansurooah
Australian Information Security Management Conference
This paper investigates the risks and vulnerabilities associated to the security of the WiMAX/802.16 broadband wireless technology. One of the other aspects of this document will be to review all the associated weaknesses to the Medium Access Control (MAC) layer and at the physical (PHY) layer. The risks and impacts are assessed according to a systematic approach. The approach or methodology is used is according to the European Telecommunication Standards Institute (ETSI). These threats are enumerated and classified accordingly to their risk levels.
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 …
