Why Your API Access Control Is a Trust Boundary Problem

Episode 31 of The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers. Hosts Lucas and Luna drill into API access control — specifically, why most teams design it as a permission matrix when they should be treating it as a trust boundary between internal systems. Using the March 2026 Snowflake misconfiguration incident as a case study, Lucas walks through how a single over-permissioned service account in a data warehouse exposed internal dashboards that should have been firewalled. Luna challenges whether API gateways alone can solve the problem, and Lucas argues for a network-segmentation-first approach. The conversation covers workload identity federation, OAuth device flow, and the concrete audit-log query that would have caught the Snowflake leak in under a minute. If you build APIs that talk to databases, this is the episode that will make you rethink your service-to-service auth model. #APIAccessControl #TrustBoundary #Snowflake #WorkloadIdentity #OAuthDeviceFlow #NetworkSegmentation #ServiceAccount #CloudSecurity #AuditLog #IdentityFederation #DevTools #BusinessAndTechnology #Infrastructure #APISecurity #FexingoBusiness #BusinessPodcast #DataLeak #Misconfiguration Keep every episode free: buymeacoffee.com/fexingo
