Security Monkey is a cloud security monitoring tool that tracks policy changes and configuration issues across AWS and GCP accounts. The tool provides continuous monitoring capabilities for cloud infrastructure, detecting insecure configurations and policy modifications in real-time. The platform offers support for OpenStack public and private clouds, extending its monitoring capabilities beyond major cloud providers. It includes functionality to monitor GitHub organizations, teams, and repositories, providing centralized visibility across development environments. Security Monkey maintains historical state information, allowing users to track exactly what changed and when modifications occurred. The tool features a unified web interface for browsing and searching across multiple accounts, regions, and cloud services. The system supports extensibility through custom account types, watchers, auditors, and alerters, enabling organizations to adapt the tool to their specific monitoring requirements. It runs on CPython 2.7 and is compatible with Ubuntu Linux and OS X operating systems. Note: Security Monkey entered maintenance mode and reached end-of-life in 2020, with Netflix reducing support for the project.
