dos-defense-and-mitigation

Design DoS-resistant systems or respond to an active denial-of-service attack. Use this skill when designing a new service and want to evaluate its attack surface and build in layered defenses, assessing whether a production system's architecture is DoS-hardened, investigating a traffic spike to determine whether it is an attack or a self-inflicted surge, detecting a client retry storm and needing to apply backoff and jitter fixes, building or reviewing a DoS mitigation system (detection + response pipeline), or deciding how to respond strategically to an ongoing attack without leaking information about your defenses to the adversary.
