Germany’s BSI issues guidelines to counter evasion attacks targeting LLMs

Germany’s BSI released guidance on countering LLM evasion attacks, detailing threats like prompt injection, jailbreaks, and adversarial inputs, and recommending a defense-in-depth approach that combines secure system prompts, content filtering, sandboxing, trusted retrieval (RAG), anomaly monitoring, adversarial testing, and governance. The publication includes a practical checklist and use cases to help developers and IT managers integrate these safeguards into operational AI systems, aiming to raise attacker cost and reduce potential harm while acknowledging no single control is sufficient.
