What NIST SP 800-204 (Microservices) requires
NIST SP 800-204 establishes stringent security strategies for microservice-based applications, mandating a defense-in-depth architecture. Compliance requires the deployment and configuration of an API gateway to mediate all ingress traffic, complemented by a service mesh for managing and securing inter-service communication. All service-to-service interactions must be encrypted and authenticated through the mandatory enforcement of mutual TLS. Authentication mechanisms will employ JSON Web Token validation, while access control strictly adheres to a least privilege access enforced model. The network posture must adopt a zero-trust stance, where a default network policy denies all connections, and all egress traffic is explicitly controlled. System observability is paramount, necessitating that log correlation is enabled across the distributed environment alongside active runtime security monitoring for continuous threat detection. From a vulnerability management perspective, a zero-tolerance policy is enforced for critical vulnerabilities in container images, demanding a scan threshold set to zero. Furthermore, secrets management must be externalized from application code, and API rate limiting needs to be enabled to protect against denial-of-service attacks and abuse.
