Mapping Trusted Systems Technologies to E-security Requirements. A new software based approach, strongly guided by national and international security standards based upon mandatory access control, is required to simplify for management the protection of their information infrastructure. This will be in the form of a security definition toolset aligned to trusted systems technologies currently under consideration internationally. No such trusted system has been developed to address current comme ....Mapping Trusted Systems Technologies to E-security Requirements. A new software based approach, strongly guided by national and international security standards based upon mandatory access control, is required to simplify for management the protection of their information infrastructure. This will be in the form of a security definition toolset aligned to trusted systems technologies currently under consideration internationally. No such trusted system has been developed to address current commercial IT product environments. The safety and security of information systems against attack and illicit usage form an essential component of ?National Information Infrastructure Protection (NIIP)?, a move to better ?e-security?. Existing commercial (untrusted) operating systems lack the critical security bases for e-security making e-applications vulnerable to tampering and bypass which can cause failures in overall system security.Read moreRead less

Guaranteeing information security is of critical national importance, especially in the current political climate. Devices intended to safeguard Australia's electronic communications must be proven secure using leading-edge techniques. Currently, evaluation of such devices relies on informal procedures and the experience of individuals. This project will introduce more rigour into security evaluations by adapting techniques from the fields of safety analysis and formal methods. In particular, mathematical concepts will be introduced using notations suitable for use by security personnel with no prior formal methods experience. The outcomes of this project will enable more efficient and effective information security evaluations.Read moreRead less

Protecting sensitive information in large network traffic flows while ensuring data usability for classification emerges as a critical problem of increasing significance. Existing techniques do not work on highly heterogeneous traffic from big-data applications for both privacy protection and classification (such as port-based and load- based methods). This project investigates new theories, methods and techniques for solving this problem. It proposes to develop a set of effective methods for privacy-preserving data publication through combining randomisation with anonymisation, and for classifying the published data through uncertainty leveraging by probabilistic reasoning and accuracy lifting by inter-flow correlation analysis and active learning.Read moreRead less
