Server-To-Server Authentication Schemes

A tour of motivations, techniques, strengths, and weaknesses.

Latacora: Modern applications tend to be composed from relationships between smaller applications. Secure modern applications thus need a way to express and enforce security policies that span multiple services. This is the “server-to-server” (S2S) authentication and authorization problem (for simplicity, I’ll mash both concepts into the term “auth” for most of this post). Designers today have a lot of options for S2S auth, but there isn’t much clarity about what the options are or why you’d select any of them.
