AWS IAM Policies: Configuring Lambda and S3 Access

Securely connecting cloud resources is a fundamental skill for any modern cloud practitioner, yet managing permissions can often feel overwhelming. This course demystifies AWS Identity and Access Management (IAM) by focusing on the essential relationship between serverless compute and cloud storage. You will transition from guessing permission configurations to confidently writing precise, secure IAM policies. Through clear written explanations, you will learn to grant AWS Lambda functions exact access to S3 buckets using modern Serverless Application Model (SAM) templates and role management. What you'll learn: - Understand foundational IAM concepts, including users, groups, roles, and policies. - Write secure execution roles for AWS Lambda functions using the principle of least privilege. - Configure S3 bucket policies to safeguard your data. - Implement SAM templates to automate and deploy secure resource configurations. - Troubleshoot and test IAM policies using modern AWS policy simulator techniques. The course begins with core security terminology and foundational access management definitions before guiding you through step-by-step written tutorials on policy structure, role assumption, and SAM integration. This course is designed for beginner cloud developers, DevOps enthusiasts, and system administrators who want to master cloud security basics without any prior IAM experience.
