Aviation RBAC and ABAC: where do governance controls still fall short?

TL;DR: Aviation authorization must handle role explosion, sensitive passenger data, maintenance errors, and audit obligations across pilots, staff, systems, and AI workloads, according to Cerbos’ guide. The core issue is that static role models cannot keep pace with contextual decisions, making externalized policy enforcement the governance baseline rather than an implementation detail.

Questions worth separating out

Q: How should security teams implement RBAC and ABAC together in complex operations?

A: Use RBAC for stable job functions and ABAC for conditions that change by time, location, workflow state, or resource sensitivity.

Q: When does role-based access control stop being enough for operational systems?

A: RBAC stops being enough when access decisions depend on context that cannot be captured reliably in a role name.

Q: What breaks when authorization logic is hard-coded into each application?

A: Policy drift breaks first.

Practitioner guidance

• Separate stable roles from contextual conditions Define role membership for durable job functions, then express time, location, resource sensitivity, and workflow state as policy attributes rather than ad hoc application code.
• Centralize policy decisions for all aviation systems Route authorization through one governed decision layer so flight operations, maintenance, ticketing, and logistics enforce the same rules even when deployment models differ.
• Treat AI-assisted ordering as a governed workload identity Apply explicit thresholds, approval boundaries, and decision logs to automated part ordering so machine-driven actions remain reviewable and bounded.

Cerbos's full guide covers the operational detail this post intentionally leaves for the source:

• Step-by-step Cerbos policy examples for role policies, resource policies, and derived roles in aviation workflows.
• Deployment model guidance for service, sidecar, and DaemonSet patterns across low-latency and centralized decision needs.
• Policy folder structure and YAML examples for flight schedules, ticketing, maintenance logs, and MCP parts ordering.
• Decision logging and centralized audit trail examples for compliance reporting and investigation support.
