AWS Config Rules Repository is a community-maintained collection of custom AWS Config rules designed to evaluate the configuration settings of AWS resources for compliance and security purposes. The repository provides pre-built Config rules that organizations can deploy to monitor and assess their AWS infrastructure against various compliance standards and security best practices. Each rule is designed to check specific configuration aspects of AWS resources and can trigger alerts or remediation actions when non-compliant configurations are detected. The repository includes rules developed using the Rule Development Kit (RDK) framework, with each rule containing its own directory structure and configuration files including parameters.json. Users can deploy these rules either through the RDK tool or manually using the provided sample functions. The project integrates with related AWS tools including RDKLib for running rules at scale and the Config Rules Engine for deploying and managing rules across multiple environments. Contributors can submit new rules following the established development guidelines and testing procedures. Rules in the repository cover various AWS services and security configurations, helping organizations maintain compliance with industry standards and internal security policies through automated configuration monitoring and assessment.
