As artificial intelligence continues to enhance biological innovation, the potential for misuse must be addressed to fully unlock the potential societal benefits. While significant work has been done to evaluate general-purpose AI and specialized biological design tools (BDTs) for biothreat creation risks, actionable steps to mitigate the risk of AI-enabled biothreat creation are underdeveloped. This paper provides policy and technology strategies collected from a diverse range of sources placed in the context of an organizing framework aligned with steps in the AI-enabled creation of a biothreat. After collating previous reports (typically on one or a small set of mitigation options) and evaluating the proposed mitigation options by projected feasibility and impact, we prioritize development of seven mitigation strategies (with a total of twelve individual mitigations): model unlearning and information removal techniques (a combination of five mitigations), classifier-based input and output filtering for BDTs, AI agents for biosecurity, safety bug bounty programs, ensuring enforcement of existing material/equipment protections, enhancing biosurveillance and bioattribution, and screening metadata/audit logs before DNA synthesis. We invite collaboration among policymakers, researchers, and technologists to refine and implement these strategies into a strong layered defense, ensuring that AI can be used safely and securely to the benefit of all.
