Securing Your API: The Checklist We Actually Use
Sample post — the controls that catch the most real-world API bugs.
Start with authentication and authorization
Most serious API findings are broken object-level authorization (BOLA) — a user reading data that is not theirs by changing an ID.
The checklist
- Authenticate every endpoint; there is no "internal only" on the internet.
- Authorize per object, not just per route.
- Validate and constrain every input.
- Rate-limit and monitor for abuse.
- Never leak stack traces or secrets in error responses.
Automated scanners miss business-logic flaws. Manual review is where the value is.
