The Zero Trust Microservices Architecture redefines digital trust in the era of distributed systems. By moving past dated perimeter models, the approach validates every single API call as a potential threat surface by weaving “never trust, always verify” into the fabric of cloud-native applications. Zero Trust Microservices Architecture is an effective way to understand and combat the increasing complexity and multifaceted security threats that come with distributed cloud-native systems, especially when traditional perimeter defenses become a complete loss or insufficient to achieve a level of protection that meets our standards. This approach seeks to create a continuous framework of authentication, authorization, encryption, and monitoring for every interaction between microservices, thereby achieving a level of trustworthiness across the architecture that remains unwavering. The specific patterns encompassed within this approach include, but are not limited to, mutual TLS for transmission security, JWT-based service authentication, least-privilege access, policy-based security in a service mesh architecture, and real-time anomaly detection to identify and respond to system breaches, from botnets to insider threats. This informative webinar is meant to provide engineers with real and actionable strategies to protect microservices from a range of external and insider threats using case studies and architectural best practices to develop infrastructure that is not only scalable but can also withstand security attacks as they evolve.
