What you'll learn

Subtle logic flaws, race conditions, and abuse can break even well-authenticated Go services. In this course, Secure Business Logic for Go Applications, you’ll learn to design and ship resilient workflow safeguards end to end. First, you’ll explore enforcing ordered, stateful business processes so that sequential steps only happen in the correct order. Next, you’ll discover concurrency-safe patterns—idempotency, optimistic/pessimistic locking, and safe retries—to eliminate race conditions. Finally, you’ll learn how to resist DoS and abuse with rate limits by user token and IP and how to require verified-channel confirmations (signed, one-time email links) for sensitive actions. When you’re finished with this course, you’ll have the skills and knowledge of secure business logic for Go services needed to confidently protect critical workflows in production.
