API Security in Go: Rate Limiting, JWT Authentication, and RBAC
Introduction API security isn’t optional—it’s fundamental. According to the 2023 State of API Security Report, 94% of organizations experienced API security incidents, with exposed APIs becoming the primary attack vector for data breaches. As APIs power everything from mobile apps to microservices architectures, a single vulnerability can cascade into system-wide failures, data leaks, or complete service disruption.
Go’s combination of simplicity, performance, and robust concurrency makes it ideal for building secure APIs.
