Medical Insecurity: When One Size Does Not Fit All, Patricia A. Williams Dec 2007

Medical Insecurity: When One Size Does Not Fit All, Patricia A. Williams

Australian Information Security Management Conference

Security is most commonly seen as a business concept. This is one reason for the poor uptake and implementation of standard security processes in non-business environments such as general medical practice. It is clear that protection of sensitive patient information is imperative yet the overarching conceptual business processes required to ensure this protection are not well suited to this context. The issue of sensitivity of information, together with the expectation that security can be effectively implemented by non-security trained professionals creates an insecure environment. The general security processes used by business, including those for risk assessment, are difficult to operationally …


A Single Channel Attack On 915mhz Radio Frequency Identification Systems, Christopher Bolan Dec 2007

A Single Channel Attack On 915mhz Radio Frequency Identification Systems, Christopher Bolan

Australian Information Security Management Conference

There has been some speculation as to the protection offered by the Frequency Hopping Spread Spectrum utilised by RFID technology. This paper explores the construction of an attack based on the broadcast of an attack signal in a single channel. The study details an experiment on two groups of tags where the experimental group are exposed to an attack signal broadcast on a single channel. With consistent findings across both control and experimental groups the experiment clearly demonstrates that FHSS offers no protection against such an attack.


Teaching Php With Security In Mind, Greg Baatard Dec 2007

Teaching Php With Security In Mind, Greg Baatard

Australian Information Security Management Conference

The PHP server-side scripting language has found significant popularity due to its accessibility, simplicity and affordability. With the deployment of PHP-inclusive web development environments becoming easier, universities have begun to offer units of study in the language. However, students coming from a background of HTML-based web development will often not be adequately prepared to consider the security implications associated with a powerful scripting language. It is important that students are taught to recognise and respond to the security implications of their code from an early stage, as a matter of good programming practice. This paper demonstrates how security teachings can …


A Comprehensive Firewall Testing Methodology, Murray Brand Dec 2007

A Comprehensive Firewall Testing Methodology, Murray Brand

Australian Information Security Management Conference

This paper proposes an all encompassing test methodology for firewalls. It extends the life cycle model to revisit the major phases of the life cycle after a firewall is in service as foundations for the tests. The focus of the tests is to show that the firewall is, or isn’t, still fit for purpose. It also focuses on the traceability between business requirements through to policy, rule sets, physical design, implementation, egress and ingress testing, monitoring and auditing. The guidelines are provided by a Test and Evaluation Master Plan (TEMP). The methodology is very much process driven and in keeping …


Increasing Security In The Physical Layer Of Wireless Communication, Luke Golygowski Dec 2007

Increasing Security In The Physical Layer Of Wireless Communication, Luke Golygowski

Australian Information Security Management Conference

This paper introduces a concept of increasing securing in the Physical layer (PHY) of wireless communication. It gives a short description of current status of wireless standards and their security. Despite the existence of advanced security protocols such as IEEE 802.11i or WLAN VPNs, wireless networks still remain vulnerable to denial-of-service (DoS) attacks aiming at PHY and Data Link Layers. The new solution challenges the problems with the currently defined PHY and Data Link layers. The concept introduced here, holds a promise of descending with some of the security measures to the lower layers of the TCP/IP and in this …

The Importance Of Human Factors When Assessing Outsourcing Security Risks, Carl Colwill, Andy Jones

Australian Information Security Management Conference

The word is becoming increasingly interconnected and ways of doing business are evolving rapidly. Communications technology is ubiquitous and reliable and businesses are continuously seeking ways in which systems can be exploited to improve resilience, become more efficient and reduce costs. One way in which organisations seek to achieve this is by concentrating their efforts on core business processes and outsourcing non-core functions. However, outsourcing - and particularly offshoring - presents many security issues that must be considered throughout the lifetime of contracts. The scale of outsourcing and increasing technological and security complexity is making this task more difficult. Often …


The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke Dec 2007

The Need For An Investigation Into Possible Security Threats Associated With Sql Based Emr Software, Lee Heinke

Australian Information Security Management Conference

An increasing amount of E-health software packages are being bundled with Standard Query Language (SQL) databases as a means of storing Electronic Medical Records (EMR’s). These databases allow medical practitioners to store, change and maintain large volumes of patient information. The software that utilizes these databases pulls data directly from fields within the database based on standardized query statements. These query statements use the same methods as web-based applications to dynamically pull data from the database so it can be manipulated by the Graphical User Interface (GUI). This paper proposes a study for an investigation into the susceptibility of popular …


Securing Voip: A Framework To Mitigate Or Manage Risks, Peter James, Andrew Woodward Dec 2007

Securing Voip: A Framework To Mitigate Or Manage Risks, Peter James, Andrew Woodward

Australian Information Security Management Conference

In Australia, the past few years have seen Voice over IP (VoIP) move from a niche communications medium used by organisations with the appropriate infrastructure and capabilities to a technology that is available to any one with a good broadband connection. Driven by low cost and no cost phone calls, easy to use VoIP clients and increasingly reliable connections, VoIP is replacing the Public Switch Telephone Network (PSTN) in a growing number of households. VoIP adoption appears to be following a similar path to early Internet adoption, namely little awareness by users of the security implications. Lack of concern about …

How Safe Is Azeroth, Or, Are Mmorpgs A Security Risk?, An Hilven, Andrew Woodward

Australian Information Security Management Conference

Massive Multiplayer Online Role Playing Games (MMORPGs) are at a basic level a networked application. Blizzard’s World of Warcraft is currently the largest example of such a type of application, with over nine million subscribers at last count. Whilst the idea of researching a game for network security may sound trivial, nine million potential backdoors into home and business computers is not. The ports used by the game, as well as authentication methods and client update programs were examined using packet analysis software. No obvious vulnerabilities were discovered as a result of this analysis. In addition to this analysis, an …

Recent surveys show that there are increased concerns about computer crime. The paper will focus upon recent national security surveys from Australia and New Zealand and the trends that this research shows. Is it fair to assume the security practices are the same all over the world? The paper looks at security practices from a number of different countries perspectives and shows that security practices are not generic and vary from country to country. The paper will also evaluate …


Virtual Radicalisation: Challenges For Police, Simon O'Rourke Dec 2007

Virtual Radicalisation: Challenges For Police, Simon O'Rourke

Australian Information Warfare and Security Conference

Recent advances in communications technology are providing a medium for individuals or groups to subscribe to extremist worldviews and form networks, access training and obtain information, whilst remaining virtually undetected in the online world. Whilst the Internet is facilitating global virtual communities like Second Life, MySpace and Facebook it is also providing an anonymous meeting place for disenfranchised individuals to gather, share ideas, post and exchange information regarding their particular ideology. This virtual community provides a sense of belonging to a global cause in which the actions of an individual can be aligned to, and seen to contribute towards something …

In this context, the systems modeling benchmarks will assess the practicality of CPNTools to the task of modelling critical infrastructure systems.


Managing Analysis, David Shaw Dec 2007

Managing Analysis, David Shaw

Australian Information Warfare and Security Conference

The Intelligence profession requires effective management to function properly and professional discourse highlights the changing nature of intelligence work. Highlighted “failures” are linked to organizational structures and ethos, and proposals to address the problems include discussion of human and organizational factors with recommendations that address the issues. However, optimising the intelligence process may not be a simple case of applying management techniques as the work relies substantially on individual endeavour. Innovative management techniques are needed and these should be grounded in recognising the peculiar nature of analysis and the skill set required.


Commercial Critical Systems And Critical Infrastructure Protection: A Future Research Agenda, Matthew J. Warren, Shona Leitch Dec 2007

Commercial Critical Systems And Critical Infrastructure Protection: A Future Research Agenda, Matthew J. Warren, Shona Leitch

Australian Information Warfare and Security Conference

Secure management of Australia’s commercial critical infrastructure presents ongoing challenges to owners and the government. Although it is currently managed through high-level information sharing via collaboration, but does this suit the commercial sector. One of the issues facing Australia is that the majority of critical infrastructure resides under the control of the business sector and certain aspects such of the critical infrastructure such as Supply Chain Management (SCM) systems are distributed entities and not a single entity. The paper focuses upon the security issues associated with SCM systems and critical infrastructure protection


Space As A New Sphere Of Future Information Warfare, Martti Lehto Dec 2007

Space As A New Sphere Of Future Information Warfare, Martti Lehto

Australian Information Warfare and Security Conference

Air power has seen constant development from the Wright Flyer’s first flight at Kitty Hawk on December 17, 1903 via the advent of the jet age with the service entry of the Messerschmitt Me 262 in 1942, to today’s multirole fighters (F-35 Joint Strike Fighter) and stealth aircraft (B-2 Spirit multi-role bomber). As a result of this evolution of one hundred years air power has emerged as a central component in power projection. As General William Mitchell said: ”Neither armies nor navies can exist unless the air is controlled over them.” (Mitchell 1925, xv)We have witnessed a corresponding development in …


Light-Weight Encryption Schemes For Multimedia Data, Feng Bao, Robert H. Deng Nov 2007

Light-Weight Encryption Schemes For Multimedia Data, Feng Bao, Robert H. Deng

Research Collection School Of Computing and Information Systems

Due to the pervasiveness of high-speed networks and multimedia communications and storage, the demand for highspeed cryptosystems is ever increasing. It is widely believed that there is a tradeoff between speed and security in cryptosystem design. No existing encryption algorithms are both fast enough for high-speed operation and sufficiently secure to withstand powerful cryptanalysis. In this paper, we propose and analyze a generic construction of high-speed encryption schemes. Our solution is based on the fact that there exist secure but relatively slow block ciphers, e. g. AES, and super-fast but relatively weaker stream ciphers. We then combine a secure block …


An Information-Sharing Based Anti-Phishing System, Yueqing Cheng, Zhen Yuan, Lei Ma, Robert H. Deng Nov 2007

An Information-Sharing Based Anti-Phishing System, Yueqing Cheng, Zhen Yuan, Lei Ma, Robert H. Deng

Research Collection School Of Computing and Information Systems

This paper presents the design of an informationsharing based or server-assisted anti-phishing system. The system follows a client-server architecture and makes decision based on not only client side heuristics but also collective information from multiple clients. When visiting a web site, a client side proxy, installed as a plug-in to a browser, decides on the legitimacy of the web site based on a combination of white list, black list and heuristics. In case the client side proxy does not have sufficient information to make a clear judgment, it reports the suspicious site to a central server which has access to …


Npake+: A Hierarchical Group Password-Authenticated Key Exchange Protocol Using Different Passwords, Zhiguo Wan, Robert H. Deng, Feng Bao, Bart Preneel Oct 2007

Npake+: A Hierarchical Group Password-Authenticated Key Exchange Protocol Using Different Passwords, Zhiguo Wan, Robert H. Deng, Feng Bao, Bart Preneel

Research Collection School Of Computing and Information Systems

Although two-party password-authenticated key exchange (PAKE) protocols have been intensively studied in recent years, group PAKE protocols have received little attention. In this paper, we propose a hierarchical group PAKE protocol nPAKE+ protocol under the setting where each party shares an independent password with a trusted server. The nPAKE+ protocol is a novel combination of the hierarchical key tree structure and the password-based Diffie-Hellman exchange, and hence it achieves substantial gain in computation efficiency. In particular, the computation cost for each client in our protocol is only O(logn). Additionally, the hierarchical feature of nPAKE+ enables every subgroup obtains their own …


Flexible Access Control To Jpeg 2000 Image Code-Streams, Yongdong Wu, Di Ma, Robert H. Deng Oct 2007

Flexible Access Control To Jpeg 2000 Image Code-Streams, Yongdong Wu, Di Ma, Robert H. Deng

Research Collection School Of Computing and Information Systems

JPEG 2000 is an international standard for still image compression in the 21st century. Part 8 of the standard, named JPSEC, is concerned with all the security aspects, in particular to access control and authentication. This paper presents a novel access control scheme for JPEG 2000 image code-streams. The proposed scheme is secure against collusion attacks and highly efficient. The scheme is also very flexible, allowing access control to JPEG 2000 image code-streams according to any combination of resolution, quality layer and region of interest. The "encrypt once, decrypt many ways" property of our scheme is designed to work seamlessly …

Collaborative, Trust-Based Security Mechanisms For A National Utility Intranet, Gregory M. Coates Sep 2007

Collaborative, Trust-Based Security Mechanisms For A National Utility Intranet, Gregory M. Coates

Theses and Dissertations

This thesis investigates security mechanisms for utility control and protection networks using IP-based protocol interaction. It proposes flexible, cost-effective solutions in strategic locations to protect transitioning legacy and full IP-standards architectures. It also demonstrates how operational signatures can be defined to enact organizationally-unique standard operating procedures for zero failure in environments with varying levels of uncertainty and trust. The research evaluates layering encryption, authentication, traffic filtering, content checks, and event correlation mechanisms over time-critical primary and backup control/protection signaling to prevent disruption by internal and external malicious activity or errors. Finally, it shows how a regional/national implementation can protect private …


Anonymous And Authenticated Key Exchange For Roaming Networks, Guomin Yang, Duncan S. Wong, Xiaotie Deng Sep 2007

Anonymous And Authenticated Key Exchange For Roaming Networks, Guomin Yang, Duncan S. Wong, Xiaotie Deng

Research Collection School Of Computing and Information Systems

User privacy is a notable security issue in wireless communications. It concerns about user identities from being exposed and user movements and whereabouts from being tracked. The concern of user privacy is particularly signified in systems which support roaming when users are able to hop across networks administered by different operators. In this paper, we propose a novel construction approach of anonymous and authenticated key exchange protocols for a roaming user and a visiting server to establish a random session key in such a way that the visiting server authenticates the user's home server without knowing exactly who the user …
