SPIFFE

As explained in Software Security for Developers

SPIFFE is a standard framework for securely identifying workloads and providing them with verifiable identities.

SPIFFE is a standard framework for securely identifying workloads and providing verifiable identities. In service-to-service communication, it helps establish trust between microservices without relying only on manually managed credentials. section 3.1.2 section 3.3

A practical use case is mutual TLS (mTLS): services exchange X.509 certificates, establish a secure TLS connection, and identify callers from certificate fields. Service meshes and SPIFFE simplify deploying and managing this stronger form of TLS. section 3.1.2

SPIFFE belongs alongside service meshes, API gateways, credential storage, Kubernetes, X.509 certificates, and OAuth 2.0 as part of a cloud-native security toolkit. section 3.3

How Software Security for Developers covers it

How deep it goes
Explains SPIFFE’s role in trust bootstrapping and mTLS management but defers protocol and configuration details.
Examples
Uses service-to-service mTLS and caller identity extracted from X.509 certificate fields as its concrete security example.
What it assumes
Assumes familiarity with TLS and X.509 certificates while placing SPIFFE among broader cryptographic and service-security technologies.
What you can do after
Evaluate SPIFFE as a way to bootstrap trust and simplify managed mTLS between microservices.
How it connects
Connects SPIFFE with mTLS, service meshes, X.509 certificates, TLS, credential storage, and Kubernetes.
