Secure Cloud Access with AWS Security Token Service (STS)

In modern cloud environments, relying on permanent access keys is a major security risk that can lead to costly data breaches. Understanding how to issue short-lived, temporary credentials is the foundation of modern cloud security. This course teaches you how to leverage AWS Security Token Service (STS) to implement temporary credentials, enforce the principle of least privilege, and secure cross-account access. You will learn to read and write secure IAM policies, configure roles, and securely delegate access without sharing long-term credentials. What you'll learn: - Understand the fundamental concepts of AWS STS, temporary credentials, and how they differ from long-term IAM user keys. - Configure IAM roles and trust relationships to enable secure, temporary cross-account access. - Apply the principle of least privilege using session policies and external IDs for third-party integrations. - Implement multi-factor authentication requirements for elevated STS operations. - Explore modern security patterns like Zero Trust and IAM Roles Anywhere for on-premises workloads. You will start with core security definitions and terminology before moving on to step-by-step written walkthroughs of STS API calls, trust policies, and credential-handling scenarios. This text-only course is designed for beginner cloud administrators, security enthusiasts, and developers who want to master secure access management. No prior security experience is required.
