The Intelligent Security theme focuses on the development of cyber security applications using Artificial Intelligence (AI) methods. We explore machine learning, deep learning, and emerging AI paradigms. Existing AI techniques have proven capability across a plethora of problems and scales. The increase in everything-connected, online systems that both sense from and interact with the physical world poses a security risk and provides an abundance of data. The extent to which countries such as Australia are already dependent on Cyber-Physical Systems (CPS), Internet of Things (IoT), and Industrial IoT (IIoT), is projected to increase, the impact of any disruption is potentially catastrophic.
