Cyber-Physical Systems (CPS) are becoming increasingly important in modern infrastructures an‎d are facing increasing levels of cyber-threats that can interrupt operations an‎d compromise safety. This seminar will discuss the existing approaches to cyber-security for CPS, describing all their strengths an‎d weaknesses, in addition to eva‎luating their static nature, an‎d their lack in response appropriately to the evolving attacks, along with their lack in real time response. While Reinforcement Learning an‎d Deep Reinforcement Learning methods have presented potential solutions, there are still challenges to overcome regarding false positives an‎d providing stability to the system. Building an‎d expan‎ding upon this review, a multi-layered DRL-based architecture is proposed that includes the layers of data collection, data pre-processing, decision making, action execution, an‎d feedback. A Proximal Policy Optimization (PPO) agent is proposed to allow the CPS system to provide adaptive, real-time cyber-defenses in an ever-changing lan‎dscape of attacks
