L7 PUT

HTTP PUT flood

Update-oriented REST traffic replacing or overwriting resources. Tests idempotency handling and storage write paths.

How it works

  1. Full resource body sent with PUT method.
  2. Storage and validation cost per request is typically higher than GET.
  3. Useful for API gateway and object-store limit testing.

What to watch in Engarde

  • 5xx and timeout on update endpoints.
  • Lock contention on shared resources.

Running this simulation

Enable PUT in Engarde DDoS against authorized API endpoints; compare with GET baseline reports.

Mitigation perspective

Method-specific rate limits and payload size caps at API gateway.
