Researchers have developed a new method for automatically responding to cyberattacks on Operational Technology (OT) systems, which are crucial for monitoring and controlling industrial processes. The approach models intrusion response using a partially observable Markov decision process (POMDP) and incorporates realistic partial observability based on traffic measurements. Learning-based solutions, specifically Proximal Policy Optimization (PPO), were used to create effective response strategies that were tested on an emulated OT system and demonstrated success against various MITRE attacks.
