The Cyber Trainer System is a core infrastructure that is used for all training. It is specially designed to train cyber defender trade craft and is capable of individual and teams-based training in a near real-world network environment. A Security Operation Centre (SOC) environment is used and trainees are tested through customised exercise scenarios that are designed to develop their application of cyber security tools for network protection. All activities are tracked and recorded for detailed After Action Review (AAR). The trainees will then be assessed systematically on their ability to apply timely and effective course of actions.
