Policy-Based Authorization for Government APIs **[API Evangelist](https://daily.dev/sources/apievangelist)** · 6 min read · 0 upvotes · 0 comments ## Summary A deep dive into Germany's federal API authorization blueprint, focusing on policy-based access control architecture. Covers the four core roles from XACML/NIST SP 800-162 — Policy Enforcement Point (PEP), Policy Decision Point (PDP), Policy Administration Point (PAP), and Policy Information Point (PIP) — and how Germany applies a hybrid PBAC/ABAC model. Key design decisions include a coarse-grained/fine-grained split (central vs. domain-level), offline-resilient PDPs via local caching and polling, and standardization on OpenID AuthZEN as the PEP-to-PDP interface. Open Policy Agent is highlighted as an already-common government tool that fits this pattern. The post argues against scattered, per-service authorization logic and advocates for treating authorization as shared, auditable infrastructure. ## Full article daily.dev links to this article rather than hosting it.
