Cloud security is our specialty. If your team needs expert help securing or operating AWS environments, visit In this lesson from our AWS Certified Security Specialty (SCS-C03) course, we explore Amazon EventBridge and how it enables event-driven automation in AWS. We start with the fundamentals: • What Amazon EventBridge is • How event-driven architecture works • Event buses vs. pipes • Rules and event patterns • Default vs. custom event buses Then we move into a practical security-focused demo where we: • Create an SNS topic • Subscribe via email • Build an EventBridge rule that listens for GuardDuty findings • Use an input transformer to format alert emails • Generate a GuardDuty sample finding via AWS CLI • Validate that the alert is triggered successfully This lesson demonstrates how to automate incident notifications using GuardDuty + EventBridge + SNS — a foundational pattern for real-world cloud security automation. You’ll also learn: • How EventBridge routes AWS service events • How to match GuardDuty findings with event patterns • How to format event data for human-readable notifications • How to simulate findings safely for testing Event-driven security is a powerful approach to reducing detection and response time in AWS environments, and this architecture pattern is frequently tested on the AWS Security Specialty exam. By the end of this lesson, you’ll understand how to connect threat detection services to automated workflows using native AWS services. #AWS #AWSCertified #AWSSecuritySpecialty
