SPIFFE
SPIFFE is a standard framework for securely identifying software workloads and enabling them to prove their identities.
Authorization in Action
SPIFFE is a standard for identifying software workloads and enabling them to prove their identities.
- How it is used
- Provides trustworthy workload identity for service-mesh authentication and authorization-context construction.
- How deep it goes
- Explains IDs, SVID formats, mTLS use, and policy integration, but stops short of defining workload-registration operations.
- Examples
- Uses a Docs service, sidecar proxy, SPIFFE URI, X.509 certificate, JWT, and Legal-document indexing policy.
- What you can do after
- Operate/configure authorization flows that authenticate workloads and pass verified workload identity into policy evaluation.
Software Security for Developers
SPIFFE is a standard framework for securely identifying workloads and providing them with verifiable identities.
- How it is used
- Supports workload identity and trust bootstrapping for secure microservice communication.
- 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 you can do after
- Evaluate SPIFFE as a way to bootstrap trust and simplify managed mTLS between microservices.
