IAM Zero is an identity and access management tool that identifies IAM issues and generates least-privilege policy recommendations for cloud environments. The tool operates by capturing errors from applications or command-line operations and analyzing them against Access Advisory lists to detect overprivileged or misconfigured access permissions. It automatically matches captured errors with relevant IAM policies and provides customized recommendations tailored to specific cloud environments. IAM Zero focuses on implementing the principle of least privilege by suggesting minimal required permissions based on actual usage patterns and error analysis. The tool currently supports AWS environments with planned expansion to additional cloud platforms including Google Cloud Platform (GCP), Microsoft Azure, and Kubernetes. The solution helps organizations reduce their attack surface by identifying unnecessary permissions and providing actionable recommendations for policy optimization. It streamlines the process of IAM policy creation and maintenance by automating the analysis of access patterns and generating appropriate permission sets.
