Abstract

Securing APIs in Microservices Environment

As organizations increasingly adopt microservices architectures, securing distributed APIs becomes critical and complex. This session will explore the unique security challenges that arise when APIs are decomposed across many small, interconnected services. We'll discuss strategies for robust authentication, authorization, and encryption, delving into how concepts such as service meshes and mutual TLS can effectively secure service-to-service communication. Attendees will learn to implement least-privilege principles, isolate trust boundaries, and manage secrets in a highly distributed system. In addition, the talk will cover practical tips for enforcing consistent security policies across services with an API gateway, preventing common attacks such as token theft and lateral movement. By the end, the participants will come away with proven patterns, tools, and best practices for strengthening their API security in a microservices-driven architecture.
