Identity

How does Service A know that Service B is actually Service B? In traditional networks, we trusted network location. If traffic came from the right IP, it was legitimate. Zero trust killed that assumption. Now every service must prove its identity, every time, regardless of network position. SPIFFE (Secure Production Identity Framework for Everyone) is a standard for service identity. SPIRE is its production-ready implementation. Together, they give every workload a cryptographic identity — automatically, without static secrets. ...
