securing-aws-lambda-execution-roles
Hardens AWS Lambda execution roles by writing least-privilege IAM policies, applying permission boundaries, restricting resource-based policies, validating permissions with IAM Access Analyzer, and enforcing role scoping through SCPs. Use when deploying new Lambda functions, remediating overly permissive Lambda roles found in an audit, or building reusable least-privilege IAM role templates for serverless teams.

# Securing AWS Lambda Execution Roles
## When to Use
- When deploying new Lambda functions and defining their IAM execution roles
- When remediating overly permissive Lambda roles discovered during security audits
- When implementing least-privilege access patterns for serverless architectures
- When building reusable IAM templates for Lambda functions across teams
- When Security Hub or Prowler reports Lambda functions with excessive permissions
**Do not use** for securing Lambda function invocation (use resource-based policies and API Gateway authorizers), for Lambda code security (use SAST tools), or for Lambda network security (use VPC configuration and security groups).
## Prerequisites
