Network Security Devices And Protocols Using State Model Diagrams, C. Nuangjamnong, D. Veal, S. P. Maj Dec 2007

Network Security Devices And Protocols Using State Model Diagrams, C. Nuangjamnong, D. Veal, S. P. Maj

Australian Information Security Management Conference

Network security is concerned with protecting sensitive information, limiting unauthorised access, and reinforcing network performance. An important factor in network security is encryption. Internet Security Protocol (IPSec) is the de facto open standard for encryption and replaces the older Cisco Encryption Technology (CET). Both encryption protocols are typically implemented and managed using the text based Command Line Interface (CLI). A graphical user interface (GUI) is available; however, it is not routinely used. Regardless of whether the CLI or GUI is used, both encryption suites are complex to implement and manage. State Model Diagrams (SMDs) were developed and successfully used as …

Device- Versus Network-Centric Authentication Paradigms For Mobile Devices: Operational And Perceptual Trade-Offs, S. Karatzouni, N. L. Clarke, S. M. Furnell Dec 2007

Device- Versus Network-Centric Authentication Paradigms For Mobile Devices: Operational And Perceptual Trade-Offs, S. Karatzouni, N. L. Clarke, S. M. Furnell

Australian Information Security Management Conference

The increasing capability and functionality of mobile devices is leading to a corresponding increase in the need for security to prevent unauthorised access. Indeed, as the data and services accessed via mobile devices become more sensitive, the existing method of user authentication (predominately based upon Personal Identification Numbers) appears increasingly insufficient. An alternative basis for authentication is offered by biometric approaches; which have the potential to be implemented in a non-intrusive manner and also enable authentication to be applied in an ongoing manner, beyond initial point-of-entry. However, the implementation of any authentication mechanism, particularly biometric approaches, introduces considerations of where …

Importance Of Verification And Validation Of Data Sources In Attaining Information Superiority, Gautham Kasinath, Leisa Armstrong

Australian Information Security Management Conference

Information superiority has been defined as a state that is achieved when a competitive advantage is derived from the ability to exploit a superior information position. To achieve such a superior information position enterprises and nations, alike, must not only collect and record correct, accurate, timely and useful information but also ensure that information recorded is not lost to competitors due to lack of comprehensive security and leaks. Further, enterprises that aim to attain information superiority must also ensure mechanisms of validating and verifying information to reduce the chances of mis-information. Although, research has been carried out into ways to …

Analysis Of Pki As A Means Of Securing Odf Documents, Gautham Kasinath, Leisa Armstrong Dec 2007

Analysis Of Pki As A Means Of Securing Odf Documents, Gautham Kasinath, Leisa Armstrong

Australian Information Security Management Conference

Public Key Infrastructure (PKI) has for the last two decades been a means of securing systems and communication. With the adoption of Open Document Format (ODF) as an ISO standard, the question remains if the unpopular, expensive, complex and unmaintainable PKI can prove to be a viable means of securing ODF documents. This paper analyses the drawbacks of PKI and evaluates the usefulness of PKI in provisioning robust, cheap and maintainable XML security to XML based ODF. This paper also evaluates the existing research on XML security, more specifically fine grained access control.

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.

The Information Security Ownership Question In Iso/Iec 27001 – An Implementation, Lizzie Coles-Kemp, Richard E. Overill Dec 2006

The Information Security Ownership Question In Iso/Iec 27001 – An Implementation, Lizzie Coles-Kemp, Richard E. Overill

Australian Information Security Management Conference

The information security management standard ISO/IEC 27001 is built on the notion that information security is driven by risk assessment and risk treatment. Fundamental to the success of risk assessment and treatment is the decision making process that takes risk assessment output and assigns decisions to this output in terms of risk treatment actions. It is argued that the effectiveness of the management system lies in its ability to make effective, easytoimplement and measurable decisions. One of the key issues in decision making is ownership. In this paper two aspects of information security ownership are considered: ownership of the asset …

Managing Information Security Complexity, Murray Brand Dec 2006

Managing Information Security Complexity, Murray Brand

Australian Information Security Management Conference

This paper examines using a requirements management tool as a common thread to managing the complexity of information security systems. Requirements management provides a mechanism to trace requirements through to design, implementation, operating, monitoring, reviewing, testing, and reporting by creating links to associated, critical artefacts. This is instrumental in managing complex and dynamic systems where change can impact other subsystems and associated documentation. It helps to identify the affected artefacts through many layers. Benefits to this approach would include better project planning and management, improved risk management, superior change management, ease of reuse, enhanced quality control and more effective acceptance …

The Lazarus Effect: Resurrecting Killed Rfid Tags, Christopher Bolan Dec 2006

The Lazarus Effect: Resurrecting Killed Rfid Tags, Christopher Bolan

Australian Information Security Management Conference

Several RFID Standards allow RFID Tags to be ‘killed’ using a specialised command code. ‘Killed’ RFID Tags should be irrevocably deactivated. In actuality, when a valid kill command is sent to a tag four sections of the tags management data are zeroed causing the tag to enter a ‘fault state’ and thus be ignored by RFID readers. Through the reinitialisation of these four sections to valid values it was discovered that a tag could be resurrected and function normally.
