Australian Security and Intelligence Conference
Burglary and stealing are crimes that have a significant impact and cost on its victims and society. To mitigate such crimes, property marking is a situational crime prevention strategy that attempts to prevent through dissuasion. There are many forms of property marking, yet there is limited research of its efficacy. Where there have been such studies, there has been some indications of success. Therefore, the study assessed the efficacy of property marking to reduce burglary and stealing crimes. The study undertook a quantitate approach using non-equivalent control groups to assess the geo-spatial impact of property marking when applied at a …
Does A Weak Security Discourse Provide Opportunity For Security Deviance To Flourish?, Michael P. Coole, Jeff Corkill
Does A Weak Security Discourse Provide Opportunity For Security Deviance To Flourish?, Michael P. Coole, Jeff Corkill
Australian Security and Intelligence Conference
In the years since the tragedy of 9/11 the term "security" has become a much used and abused term. As the war on terrorism has evolved, politicians of all persuasions played the security card to change law and legislation ostensibly to protect the community. Those whom provide the security assume that freedoms lost by the wider community in the name of security are in fact a fair price to pay for that security. In this environment the security discourse is diminished and this provides an opportunity for security deviance to emerge. This research used a selection of publically reported examples …

Evaluating Single Sign On Security Failure In Cloud Services, Brian Cusack, Eghbal Zadeh
Australian Information Security Management Conference
The business use of cloud computing services is motivated by the ease of use and the potential financial cost reductions. Service failure may occur when the service provider does not protect information or when the use of the services becomes overly complex and difficult. The benefits also bring optimisation challenges for the information owners who must assess the service security risk and the degree to which new human behaviours are required. In this research we look at the risk of identity theft when ease of service access is provided through a Single Sign On (SSO) authorisation and ask: What are …

Selection Of Penetration Testing Methodologies: A Comparison And Evaluation, Aleatha Shanley, Michael N. Johnstone
Australian Information Security Management Conference
Cyber security is fast becoming a strategic priority across both governments and private organisations. With technology abundantly available, and the unbridled growth in the size and complexity of information systems, cyber criminals have a multitude of targets. Therefore, cyber security assessments are becoming common practice as concerns about information security grow. Penetration testing is one strategy used to mitigate the risk of cyber-attack. Penetration testers attempt to compromise systems using the same tools and techniques as malicious attackers thus attempting to identify vulnerabilities before an attack occurs. This research details a gap analysis of the theoretical vs. the practical classification …

Behavior-Based Anomaly Detection On Big Data, Hyunjoo Kim, Jonghyun Kim, Ikkyun Kim, Tai-Myung Chung
Australian Information Security Management Conference
Recently, cyber-targeted attacks such as APT (Advanced Persistent Threat) are rapidly growing as a social and national threat. It is an intelligent cyber-attack that infiltrates the target organization and enterprise clandestinely using various methods and causes considerable damage by making a final attack after long-term and through preparations. These attacks are threatening cyber worlds such as Internet by infecting and attacking the devices on this environment with the malicious code, and by destroying them or gaining their authorities. Detecting these attacks requires collecting and analysing data from various sources (network, host, security equipment, and devices) over the long haul. Therefore, …

A Hybrid Feature Selection For Network Intrusion Detection Systems: Central Points, Nour Moustafa, Jill Slay
Australian Information Warfare and Security Conference
Network intrusion detection systems are an active area of research to identify threats that face computer networks. Network packets comprise of high dimensions which require huge effort to be examined effectively. As these dimensions contain some irrelevant features, they cause a high False Alarm Rate (FAR). In this paper, we propose a hybrid method as a feature selection, based on the central points of attribute values and an Association Rule Mining algorithm to decrease the FAR. This algorithm is designed to be implemented in a short processing time, due to its dependency on the central points of feature values with …

The Cyber Simulation Terrain: Towards An Open Source Cyber Effects Simulation Ontology, Kent O'Sullivan, Benjamin Turnbull
Australian Information Warfare and Security Conference
Cyber resilience is characterised by an ability to understand and adapt to changing network conditions, including cyber attacks. Cyber resilience may be characterised by an effects-based approach to missions or processes. One of the fundamental preconditions underpinning cyber resilience is an accurate representation of current network and machine states and what missions they are supporting. This research outlines the need for an ontological network representation, drawing on existing literature and implementations in the domain. This work then introduces an open-source ontological representation for modelling cyber assets for the purposes of Computer Network Defence. This representation encompasses computers, network connectivity, users, …
Is The Internet The Main Medium Of Transmitting Terrorism?, Hatem El Zein
Is The Internet The Main Medium Of Transmitting Terrorism?, Hatem El Zein
Australian Information Warfare and Security Conference
The influx of virtual media platforms has allowed extremists and terrorists to transmit their messages to wider audiences without passing through a gatekeeper or being a subject to editorial policies existed in traditional media outlets. Thus, extremists and terrorists exploit virtual media platforms to report their actions; propagate their ideologies and ultimately to boost their objectives, because these mediums enabled them to have control over time and space. As a result, some governments work to deprive extremists and terrorists from this 'oxygen' through monitoring the cyberspace to block the suspected virtual media platforms. The reactions of some governments to face …

Steganography As A Threat – Fairytale Or Fact?, Tom Cleary
Steganography As A Threat – Fairytale Or Fact?, Tom Cleary
Australian Digital Forensics Conference
Almost since the birth of the Internet, there has been a fear that steganographically-encoded threats would be used to bring harm. Serious consideration has been given to the idea that merely downloading an image could introduce malware. Yet, for decades, evidence of this malware channel has been missing in action. There is still an unwritten assumption that images are harmless. Many vendors have implicitly avoided producing defences against steganographic threats. Is it truly impossible to make a widely harmful exploit this way or have malicious actors accepted general wisdom? Three recent papers suggest that there may be a new chapter …

Cyber Black Box: Network Intrusion Forensics System For Collecting And Preserving Evidence Of Attack, Jong-Hyun Kim, Joo-Young Lee, Yangseo Choi, Sunoh Choi, Ik-Kyun Kim
Australian Digital Forensics Conference
Once the system is compromised, the forensics and investigation are always executed after the attacks and the loss of some useful instant evidence. Since there is no log information necessary for analyzing an attack cause after the cyber incident occurs, it is difficult to analyze the cause of an intrusion even after an intrusion event is recognized. Moreover, in an advanced cyber incident such as advanced persistent threats, several months or more are expended in only analyzing a cause, and it is difficult to find the cause with conventional security equipment. In this paper, we introduce a network intrusion forensics …

Urdu Text Steganography: Utilizing Isolated Letters, Aliya Tabassum Abbasi, Nuzhat Naqvi, Aihab Khan, Basheer Ahmad
Australian Information Security Management Conference
This paper presents an imperceptible and high capacity feature based approach which hides a secret message into Urdu text cover media by utilising all isolated letters. Existing techniques are less imperceptible and also not robust against steganalysis attacks and some of these schemes are failed to provide the better capacity rates. Previous lexical based and syntax based schemes are ineffective to provide the better capacity rate and image based approaches are not robust against format attacks. Moreover, Feature based approaches are more perceptible and thus, cannot resist against visual attacks. This paper proposes an improved algorithm that encompasses all isolated …

Blurring And Deblurring Digital Images Using The Dihedral Group, Husein Hadi Abbas Jassim, Zahir M. Hussain, Hind R.M. Shaaban, Kawther B.R. Al-Dbag
Research outputs 2014 to 2021
A new method of blurring and deblurring digital images is presented. The approach is based on using new filters generating from average filter and H-filters using the action of the dihedral group. These filters are called HB-filters; used to cause a motion blur and then deblurring affected images. Also, enhancing images using HB-filters is presented as compared to other methods like Average, Gaussian, and Motion. Results and analysis show that the HB-filters are better in peak signal to noise ratio (PSNR) and RMSE.

A Profile Of Prolonged, Persistent Ssh Attack On A Kippo Based Honeynet, Craig Valli, Priya N. Rabadia, Andrew Woodward
Research outputs 2014 to 2021
This paper is an investigation focusing on activities detected by SSH honeypots that utilised kippo honeypot software. The honeypots were located across a variety of geographical locations and operational platforms. The honeynet has suffered prolonged, persistent and attack from a /24 network which appears to be of Chinese geographical origin. In addition to these attacks, other attackers have been successful in compromising real hosts in a wide range of other countries that were subsequently involved in attacking the honeypot machines in the honeynet.
