Best Practices for API Security That Reduce Real Abuse

API security best practices for production: server-side object-level authorization, strict schema validation, tenant-aware rate limits and observability—so a valid token cannot perform invalid actions.

API security remains underprioritized as usage surges; the 2023 OWASP API Security Top 10 still leads with BOLA and broken authentication, and manual testing is needed where scanners fall short.

API security testing workflow: build a route inventory with auth, object and role context, then test authentication, object-level authorization, schema validation, state transitions and abuse cases.

Insecure direct object reference: the app exposes an object ID but never checks ownership, tenant or role—one user reads another's data; fix with centralized object authorization and negative tests.

Podcast recap with Checkmarx CTO Maty Siman on maturing application security: what shift left really means as open source, APIs, and component-based development expand the modern attack surface.

API scanner coverage vs manual validation: automate schema, injection and auth checks with proper specs and multi-role accounts; still validate IDOR, rate limits and chained impact by hand.
