The Potentials And Challenges Of Big Data In Public Health, Rena N. Vithiatharan Dec 2014

The Potentials And Challenges Of Big Data In Public Health, Rena N. Vithiatharan

Australian eHealth Informatics and Security Conference

The potential to use big data sources for public health increases with the broadening availability of data and improved methods of analysis. Whilst there are some well-known examples of the opportunistic use of big data, such as GoogleFlu, public health has not yet realised the full potential of such data sources. A literature review was undertaken to identify the potential of such data collections to impact public health, and to identify what challenges are currently limiting this potential. The potential include improved real-time analysis, research and development and genome studies. However, challenges listed are poor universal standardisation and classification, privacy …

The Bad Guys Are Using It, Are You?, Hong-Eng Koh Jan 2014

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 …

Cache-Timing Attack Against Aes Crypto System - Countermeasures Review, Yaseen H. Taha, Settana M. Abdulh, Naila A. Sadalla, Huwaida Elshoush

Australian Information Security Management Conference

Side channel attacks are based on side channel information, which is information that is leaked from encryption systems. Implementing side channel attacks is possible if and only if an attacker has access to a cryptosystem (victim) or can interact with cryptosystem remotely to compute time statistics of information that collected from targeted system. Cache timing attack is a special type of side channel attack. Here, timing information caused by cache effect is collected and analyzed by an attacker to guess sensitive information such as encryption key or plaintext. Cache timing attack against AES was known theoretically until Bernstein carry out …

A Survey Of Ipv6 Address Usage In The Public Domain Name System, Clinton R. Carpene, Andrew Woodward Jan 2014

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 …

Evaluating The Security Vulenerabilities Of The Ip6to4 Tunnelling Mechanism, Brian Cusack, Raymond Lutui Jan 2014

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 …

Design Requirements For Generating Deceptive Content To Protect Document Repositories, Ben Whitham Jan 2014

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 …

Detecting Covert Communication Channels In Raster Images, Brian Cusack, Jarrett Chambers Jan 2014

Detecting Covert Communication Channels In Raster Images, Brian Cusack, Jarrett Chambers

Australian Information Warfare and Security Conference

Digital image steganography is a method for hiding secret messages within everyday Internet communication channels. Such covert communications provide protection for communications and exploit the opportunities available in digital media. Digital image steganography makes the nature and content of a message invisible to other users by taking ordinary internet artefacts and using them as cover objects for the messages. In this paper we demonstrate the capability with raster image files and discuss the challenges of detecting such covert communications. The contribution of the research is community awareness of covert communication capability in digital media and the motivation for including such …

A User-Oriented Network Forensic Analyser: The Design Of A High-Level Protocol Analyser, D Joy, F Li, N L. Clarke, S M. Furnell Jan 2014

A User-Oriented Network Forensic Analyser: The Design Of A High-Level Protocol Analyser, D Joy, F Li, N L. Clarke, S M. Furnell

Australian Digital Forensics Conference

Network forensics is becoming an increasingly important tool in the investigation of cyber and computer-assisted crimes. Unfortunately, whilst much effort has been undertaken in developing computer forensic file system analysers (e.g. Encase and FTK), such focus has not been given to Network Forensic Analysis Tools (NFATs). The single biggest barrier to effective NFATs is the handling of large volumes of low-level traffic and being able to exact and interpret forensic artefacts and their context – for example, being able extract and render application-level objects (such as emails, web pages and documents) from the low-level TCP/IP traffic but also understand how …

Forensic Examination And Analysis Of The Prefetch Files On The Banking Trojan Malware Incidents, Andri P. Heriyanto Jan 2014

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 …

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 …

Rapid Forensic Crime Scene Analysis Using Inexpensive Sensors, Dan Blackman Jan 2014

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 …
