SPIFFE

SPIFFE (Secure Production Identity Framework For Everyone) is a set of open-source standards for securely identifying software systems in dynamic and heterogeneous environments.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md]

It provides a framework for issuing identities to workloads, such as microservices, regardless of the underlying platform or network infrastructure.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md] The specification defines the SPIFFE Verifiable Identity Document (SVID), which acts as the primary identity token for a workload, usually taking the form of a X.509 certificate.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md]

The reference implementation of the SPIFFE standard is SPIRE (the SPIFFE Runtime Environment), which handles the issuance and rotation of these identities.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md]

Use Cases

In Container orchestration platforms like Kubernetes, SPIFFE can be integrated with service meshes such as Istio to manage workload identities.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md] For example, SPIRE can be deployed as a Certificate Authority (CA) that integrates with Envoy's Secret Discovery Service (SDS) API to distribute SVIDs to proxies.^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__security__spire__README.md]
