Infection Monkey is an open-source security tool designed to test data center resilience against perimeter breaches and internal server infections. The tool consists of two main components: - Monkey: An agent that infects machines and propagates across the network using various methods - Monkey Island: A centralized server that controls the Monkey agents and provides visualization of their progress The system operates by deploying the Monkey agent, which attempts to spread laterally through the network infrastructure, simulating how an actual breach might propagate within an organization's data center environment. All activities and results are reported back to the Monkey Island server for analysis and visualization. The tool helps organizations identify vulnerabilities in their network segmentation, access controls, and internal security measures by demonstrating potential attack paths that malicious actors could exploit.
