AWS IAM Security Best Practices for Developers

Building applications on AWS requires a solid grasp of security, yet configuration mistakes in Identity and Access Management (IAM) remain a top cause of cloud vulnerabilities. This course guides you through securing your cloud resources without slowing down your development workflow. You will transition from basic security awareness to confidently designing and implementing secure, developer-focused IAM configurations. You will understand how to apply the principle of least privilege, manage temporary credentials, and automate security checks to protect your applications. What you'll learn: Understand foundational AWS IAM concepts, including users, groups, roles, and policies; Apply the principle of least privilege using additive permissions and boundary policies; Configure secure role-based access control (RBAC) and modern attribute-based access control (ABAC); Implement automated policy validation using modern tools like IAM Access Analyzer; Design isolated test environments to safely validate permission changes before production deployment; Practice writing and troubleshooting JSON policy documents through clear, written walk-throughs. The course starts with essential security definitions and foundational IAM architecture before moving into practical policy design, temporary credentials, and automated validation workflows. You will progress through written explanations, architectural breakdowns, and code-based examples designed for immediate application. This course is designed for software developers, cloud beginners, and system administrators looking to build a strong security foundation in AWS. No prior cloud security experience is required.
