An applied framework for modelling a critical infrastructure system incident

The research applies the TARDIS system security analysis and modelling framework to an adverse critical infrastructure system incident. This paper reports on the practical application of the framework to a case study based on an actual critical infrastructure system failure and the resultant implications for the system and the wider regional community. Then a reflective discussion is undertaken reviewing the TARDIS framework approaches employed within the blended hybrid approach incorporated into the framework, before speculating on future research areas of framework development and application.

Measuring public infrastructure construction impacts on economic growth

The results identify the long-run equilibrium relationships among economic variables in Australia. This study can provide policy makers with information on a one standard error shock to each variable and insights into what percentages of the forecast error variance of a variable are explained by the innovations of each variable.

Australian critical infrastructure protection : a case of two tales

The protection of critical irifrastructures and the choices made in terms of priorities and cost, all impact upon the planning, precautions and security aspects of protecting these important systems. Often the when choices made is difficult to assess at the time the decision is taken and it is only after an incident that the truth of the choices made become fit!ly evident. The paper focllses on two recent examples of Australian Critical Infrastructure protection and the issues that related to those examples.

Critical supply chain systems and critical infrastructure protection

Secure management of Australia's commercial critical infrastructure presents ongoing challenges to both the owners of this infrastructure as well as to the government. It is currently managed through high-level information sharing via collaboration but does this situation 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 across a number of entities. The paper focuses upon the security and risk issues associated with SCM systems within the realms of critical infrastructure protection.

Creating an Innovation Exception? Copyright Law as the Infrastructure for Innovation

Innovation is clearly essential for economic growth, cultural development and personal autonomy. Yet the relationship between innovation and copyright law in Australia is uncertain and perhaps overly restrictive. After the Australia-United States Free Trade Agreement Australia now has a copyright regime that can broadly be
described as a lock up and lock out scheme. Whilst the Australian Government has paid lip service to innovation the Australian Copyright Act, which provides the essential legal infrastructure for innovation, now privileges the rights of owners over the interests of the public. In particular, the Copyright Act neglects to create a specific exception for technology innovation. If there is to be some coherence in Australia
thinking with regards to innovation and copyright policy it is crucial that such an exception be created. Arguably, it is possible that such an exception can withstand the scrutiny of the three step test. At present the only ‘exception’ that can be said to exist is in the form of the limits of the authorisation liability provisions or the ISP safe harbour scheme. Australian copyright law needs something more substantial than that
and needs for there to be a clear hierarchy between the exceptions and the liability provisions.

Challenges to infrastructure delivery during the economic downturn : a qualitative analysis

Infrastructure plays a key role in creating and maintaining sustainable economic growth and a prosperous community. Infrastructure projects generally require a large amount of capital investment, which motivates involvement from the private sector in the delivery process. The Global Financial Crisis placed enormous pressure on both the public and private sectors, as the ability to borrow money for an extended tenor was greatly reduced. This study adopts a qualitative approach to analyse the challenges facing the delivery of infrastructure projects in an Australian context by considering the impacts of the Global Financial Crisis. It is found that the availability of resources and finance are perceived as the biggest challenges, with resources being more of a concern than finance to interviewees. In addition to these findings, ways in which the private sector can be better involved in the infrastructure delivery is discussed.

Towards the development of a construction supply chain transaction cost economic model for strategic infrastructure procurement evaluation

Australia has adopted public-private partnership (PPP) as a major strategy for procuring infrastructure for decades. However, even though considered to be a mature and sophisticated market, several major
failures have occurred resulting in increasing financial burdens on taxpayers. Failures have typically been traced back to economic evaluation and, in particular, value-for-money across the supply chain
in the original proposal. However, the literature review identified that there was no economic model that evaluated holistically the transaction costs of PPPs across the supply chain. In this paper, theories of transaction cost economics and construction supply chain economics are critiqued and analysed in order to develop a strategic infrastructure procurement evaluation model. The model will offer decision makers with an insight into project life cycle economic outcomes needed to successfully deliver PPPs.

The pricing of infrastructure initial public offerings : evidence from Australia

This paper explores first-day returns on infrastructure entity initial public offerings (IPOs) in Australia from 1996 to 2007. While a good deal has been written on the first-day returns of industrial and mining company IPOs and Real Estate Investment Trust IPOs, first-day returns of infrastructure entity IPOs have yet to be reported in the literature. The study uses ordinary least squares regression analysis to identify factors that might influence the percentage first-day returns theoretically available to investing subscribers and factors that might influence the aggregate amount of money left to subscribers by issuers. The study finds that first-day returns, on average, are not significantly different from zero. There is evidence, however, that suggests higher dividend yields and higher percentage direct costs of capital raising influence these first-day returns. The study also finds that infrastructure entity IPOs that seek to raise more equity capital leave less money on the table for subscribing investors.

Modelling relational aspects of critical infrastructure systems

The relational aspects for critical infrastructure systems are not readily quantifiable as there are numerous variability’s and system dynamics that lack uniformity and are difficult to quantify. Notwithstanding this, there is a large body of existing research that is founded in the area of quantitative analysis of critical infrastructure networks, their system relationships and the resilience of these networks. However, the focus of this research is to investigate the aspect of taking a different, more generalised and holistic system perspective approach. This is to suggest that that through applying network theory and taking a ‘soft’ system-like modelling approach that this offers an alternative approach to viewing and modelling critical infrastructure system relational aspects that warrants further enquiry.

Australian national critical infrastructure protection : a case study

Australia has developed sophisticated national security policies and physical security agencies to protect against current and future security threats associated with critical infrastructure protection and cyber warfare protection. This paper will discuss some of the common security risks that face Australia and how their government policies and strategies have been developed and changed over time, for example, the proposed Australian Homeland Security department. This paper will discuss the different steps that Australia has undertaken in relation to developing national policies to deal with critical infrastructure protection.

Analysis and modelling of critical infrastructure systems

The increasing complexity and interconnectedness of critical infrastructure systems, including the information systems and communication networks that support their existence and functionality, poses questions and challenges. Particularly, in terms of modelling and analysis of the security, survivability and ultimately reliability and continued availability of critical infrastructure systems and the services they deliver to modern society. The focus of this research enquiry is with regard to critiquing and modelling critical infrastructure systems. There are numerous systems analyse and modelling approaches that outline any number of differing methodological approaches, each with their own characteristics, expertise, strengths and weaknesses. The intention of this research is to investigate the merit of applying a ‘softer’ approach to critical infrastructure system security analysis and modelling that broadly views the systems in holistic terms, including their relationships with other systems. The intention is not to discuss or criticise existing research applying quantitative approaches, but to discuss a ‘softer’ system analysis and modelling approach in a security context that is adaptable to analysis modelling of critical infrastructure systems.

Formulating an organizational knowledge strategy : the influence of existing IT infrastructure

This paper questions the influence of a pre-existing information technology (IT) infrastructure on the formulation of an organizational knowledge strategy. We draw on a classification of four different strategic views of IT infrastructure and explore how the historic investment in IT infrastructure enables and constrains the formulation of knowledge strategy in four case organizations. The four case organizations are representative of different scenarios of historic investments in IT infrastructure and knowledge strategy formulation. Our findings indicate that an IT infrastructure that is minimal or fragmented constrains the formulation of an explicit knowledge strategy. We further find that an extensive existing IT infrastructure enables the pursuit of an explicit knowledge strategy, but that even an elaborate IT infrastructure can introduce some constraints on IT facilitated knowledge processes in the organization.
