Microsoft released as open-source the CyberBattleSim Python-based toolkit which is an Enterprise Environment Simulator. The simulator was designed to support the analysis of the operations of autonomous agents in a simulated enterprise environment using a high-level abstraction of computer networks and cybersecurity concepts. The simulation environment is. parameterized by a fixed network topology and a set of vulnerabilities that agents can utilize to move laterally in the network. The goal of the attacker is to take ownership of a portion of the network by exploiting vulnerabilities that are planted in the computer nodes.”]
