Episode 73 — Handle Denial-of-Service Risks: Model DoS, Cost Bombs, and Resilience

This episode focuses on denial-of-service in AI systems, because SecAI+ expects you to defend not only availability, but also cost stability and operational continuity when models can be abused with oversized prompts, pathological inputs, or tool chains that amplify resource use. You will learn how model DoS differs from traditional API DoS, including token-based cost bombs, long-context payloads that spike compute and latency, and prompt patterns designed to trigger expensive retrieval or repeated tool calls. We will cover resilience strategies such as strict input length limits, rate limiting by identity and tenant, request prioritization, circuit breakers for tool chains, and caching where appropriate to reduce repeated heavy work. You will also learn how to monitor for early signals like sudden token consumption spikes, abnormal latency distributions, and correlated tool invocation storms, then respond with containment actions that isolate abusive clients without collapsing service for everyone. Troubleshooting topics include balancing availability protections with usability, preventing attackers from learning your thresholds through verbose errors, and designing graceful degradation modes that preserve safe core functionality under load.
