Policy Sentry is an IAM policy generator that helps developers create least privilege AWS IAM policies through an automated workflow. The tool addresses the challenge of manually writing security-conscious IAM policies, which can be tedious and time-consuming for Infrastructure as Code developers. It provides a structured approach to policy creation through a three-step process: creating templates, copying/pasting ARNs, and using write-policy commands. Key features include: - Template-based policy generation workflow - ARN-based resource specification - Command-line interface for policy writing - Cheat sheets for policy writing and IAM database queries - Python library integration for programmatic usage - Docker container support - Terraform integration capabilities - Shell completion functionality The tool is designed to help teams implement least privilege access principles without requiring embedded security expertise. It streamlines the process of researching AWS IAM documentation for actions, resources, and condition keys across various AWS services. Policy Sentry includes comprehensive documentation and tutorials to guide users through the policy creation process, making it accessible for developers who need to create secure IAM policies efficiently.
