DeepStage uses AI to learn autonomous defense against multi-stage cyberattacks

Researchers have developed DeepStage, a new framework utilizing deep reinforcement learning to create autonomous defense policies against multi-stage cyberattacks. The system models enterprise environments as partially observable Markov decision processes, fusing host and network data into provenance graphs. DeepStage employs a graph neural network and LSTM to estimate attacker stages, guiding a hierarchical agent to select optimal defense actions for monitoring, containment, and remediation. AI
