authentication-authorization

You prevent BOLA and IDOR by requiring object-level authorization checks on every API entry point. A deny-by-default policy ensures identity proof alone never grants permission for object-specific operations.

The best way to enforce tenant isolation is by applying tenant scoping directly at the query and database layers. This must be paired with structured audit logging that records allow or deny decisions without leaking sensitive resource existence signals.

Implement consistent authorization across background jobs and admin tools by centralizing policy decisions in a dedicated Policy Decision Point (PDP). This distributes enforcement consistently across all controllers, services, and scheduled tasks while maintaining auditable consistency.

Yes, centralized authorization works with step-up authentication for privileged actions. The policy framework requires step-up verification for sensitive operations while maintaining bounded authorization caching to ensure access decisions remain consistent and secure.

Your authorization model leaks resource existence because it lacks an explicit existence-leak policy. Implementing centralized policy decisions with audit-safe denials ensures denied requests return structured responses without revealing sensitive existence signals.

You need object-level authorization instead of standard role-based access control when operations require tenant-scoped, resource-specific permissions. It enforces deny-by-default rules across UI, internal RPC, and bulk imports where RBAC alone cannot prevent unauthorized object access.
