NIST SP 800-204B: Attribute-based Access Control for Microservices-based Applications using a Service Mesh

The National Institute of Standards and Technology (NIST) has issued the NIST SP 800-204B Attribute-based Access Control for Microservices-based Applications using a Service Mesh.

The Special Publication (SP) 800-204B provides deployment guidance for an authentication and
authorization framework within a service mesh for microservices-based applications.

An abstract from SP 800-204B:

Deployment architecture in cloud-native applications now consists of loosely coupled components, called microservices, with all application services provided through a dedicated infrastructure, called a service mesh, independent of the application code. Two critical security requirements in this architecture are to build (1) the concept of zero trust by enabling mutual authentication in communication between any pair of services and (2) a robust access control mechanism based on an access control such as attribute-based access control (ABAC) that can be used to express a wide set of policies and is scalable in terms of user base, objects (resources), and deployment environment. This document provides deployment guidance for building an authentication and authorization framework within the service mesh that meets these requirements. A reference platform for hosting the microservices-based application and a reference platform for the service mesh are included to illustrate the concepts in the recommendations and provide the context in terms of the components used in real-world deployments.
