Security Testing for API: A Practical Workflow for Modern Teams

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.

Practical API security guide: classify endpoints by sensitivity, enforce object-level authorization and strict token validation, and tie rate limits to accounts, tenants and costly actions—not IPs.

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.

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.

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.
