LambdaGuard is an AWS Lambda auditing tool that creates asset visibility and provides actionable security results for serverless functions. The tool performs statistical analysis of Lambda functions and examines AWS service dependencies to identify potential security issues. It conducts configuration checks from a security perspective, helping organizations understand their Lambda deployment posture. LambdaGuard can audit individual Lambda functions using their ARN or process multiple functions from an input file. The tool generates reports that can be saved to specified output directories for further analysis. The application requires Python 3.6+ and optionally Java 11 for SonarQube integration. It can be installed via PyPI or directly from the GitHub repository. AWS access is required through either configured profiles in ~/.aws/credentials or direct CLI arguments. The tool supports various command-line options for flexible deployment and reporting configurations.
