Principal Mapper (PMapper) is a Python-based script and library designed to analyze AWS Identity and Access Management (IAM) configurations for security risks within AWS accounts or organizations. The tool creates a directed graph model of IAM Users and Roles, enabling security professionals to identify potential privilege escalation paths and alternative attack vectors that could lead to unauthorized resource access. PMapper includes a local simulation engine that mimics AWS authorization behavior, allowing users to query whether principals have access to specific actions or resources. The tool goes beyond direct permission checks by analyzing indirect access paths, such as scenarios where a user might launch an EC2 instance with permissions to access resources they cannot directly reach. The solution supports both individual AWS accounts and AWS organizations, providing comprehensive IAM risk assessment capabilities. It requires Python 3.5+, botocore library, pydot, and graphviz for full functionality. PMapper serves as a security assessment tool for identifying misconfigurations and potential security gaps in AWS IAM implementations.
