A Systemic Review of the Cybersecurity Challenges in Australian Water Infrastructure Management

Abstract

Cybersecurity risks have become obstinate problems for critical water infrastructure management in Australia and worldwide. Water management in Australia involves a vast complex of smart technical control systems interconnected with several networks, making the infrastructure susceptible to cyber-attacks. Therefore, ensuring the use of security mechanisms in the control system modules and communication networks for sensors and actuators is vital. The statistics show that Australia is facing frequent cyber-attacks, most of which are either undetected or overlooked or require immediate response. To address these cyber risks, Australia has changed from a country with negligible recognition of attacks on critical infrastructure to a country with improved capability to manage cyber warfare. However, little attention is paid to reducing the risk of attacks to the critical water infrastructure. This study aims to evaluate Australia’s current cybersecurity attack landscape and the implemented controls for water infrastructure using a systematic literature review (SLR). This study also compares Australia in the context of global developments and proposes future research directions. The synthesis of the evidence from 271 studies in this review indicates the importance of managing security vulnerabilities and threats in SCADA water control systems, including the need to upgrade the contemporary water security architecture to mitigate emerging risks. Moreover, human resource development with a specific focus on security awareness and training for SCADA employees is found to be lacking, which will be essential for alleviating cyber threats to the water infrastructure in Australia.

Reviewing the Health Care Impacts of Attacks on Critical Infrastructure

“…22 Water systems increasingly rely on complex systems and smart technology making them vulnerable to cyber threats as well as disruptions in power. 23,24 One group looked at attacks on water infrastructure, particularly dam projects in Afghanistan, India, and Pakistan. They found in all three countries, there are water infrastructure projects that have faced scrutiny by local groups due to mistrust in the government or concern that the project is used to further domestic or foreign policy agenda.…”

Cyber Law and Cyber Security Policies in Pakistan: A Comparative Study with USA, Canada and Australia

“…The efforts to bolster its cyber defenses must contend with these geopolitical complexities. Despite these challenges, the shared commitment to enhance cyber-security emphasizes the importance of these issues on the global stage (Bello, Jahan, Farid, & Ahamed, 2022). As other countries continue to adopt strategies of each other.…”

“…The authors of [ 13 ] studied all means of maliciously accessing a plant such as through sensors, actuators, networks, and PLCs, etc. In [ 26 , 27 , 30 , 31 , 35 , 36 , 39 ], the authors studied attacks through sensors in the environment. Ref.…”

“…Cybersecurity has developed a huge interest in the water industry and some educational programs have been offered [ 20 , 21 ]. This provoked great interest in the research environment [ 22 , 23 , 24 , 25 , 26 , 27 ], as earlier cybersecurity incidents may have provided insightful information that could be used to inform current cyber defense efforts, promoting investments and initiatives and increasing their applicability and efficiency. This calls for a thorough compilation and analysis of these instances, which is currently lacking.…”
