Microservice Security: Service Cataloging and API Supply Chain Safety

Modern microservice architectures are highly distributed, making it difficult to track every API endpoint and dependency. Without clear visibility, your software supply chain becomes vulnerable to security breaches and architectural drift. This text-based course guides you through the foundational principles of service cataloging and API supply chain security. You will learn how to document your services, track dependencies, and implement security practices that keep your event-driven systems secure. What you'll learn: Understand key terminology of service cataloging and API supply chain security; Map dependencies within event-driven microservices to eliminate hidden vulnerabilities; Explore how open-source cataloging tools like Ortelius catalog and track shared components; Implement Software Bill of Materials (SBOM) concepts to secure your API pipeline; Apply zero-trust security principles to microservice communication and API endpoints; Configure basic security tracking to monitor architectural changes and drift. The course begins with foundational definitions of microservices and supply chain risks, then progresses to structured cataloging techniques, dependency mapping, and modern DevSecOps security practices. Designed for beginner developers, system architects, and security enthusiasts, this course requires no prior experience with service catalogs or advanced security tools.
