API security — fundamentals

What this is about

A layer 7 attack often looks harmless on the network graph because bandwidth stays unremarkable. Before any rule change, it should be clear what share of real traffic would be affected. When in doubt: observe before blocking — a false positive costs more than a scan that got through. A rule that never fires is more dangerous than no rule — it manufactures a false sense of safety.

What matters is not the packet rate but how expensive a single request is for the origin. What matters is not the packet rate but how expensive a single request is for the origin.
