Teaching DNA Synthesis Screening Through an Adversarial Lens

Last update - Aug 2026

TL;DR

I’ve created a ready to use lesson plan for teaching DNA synthesis screening through an adversarial lens. The lesson compares several screening methods, examines the assumptions and gaps behind each one, and connects the technical discussion to worldwide adoption and policy. The presentation is attached with speaker notes included.

This lesson reflects my own work and interpretation of the sources cited throughout the presentation. If you notice any errors, unclear points, or areas that could be improved, feel free to contact me. The topic includes dual-use material, so it should be taught responsibly.

Lesson Structure

• Set the stage - introduce DNA synthesis, screening, and the threat model.
• Traditional sequence screening - explain sequence matching and where it breaks under adversarial pressure.
• Adversarially resilient screening - show how newer approaches address those weaknesses, and what limitations remain.
• Look ahead to functional screening - introduce functional screening and the challenge of de novo designs.
• Deployment and adoption - examine adoption, market coverage, and regulation.
• Takeaways - summarize what current screening can and cannot solve, and where the field may need to go next.

Teaching Approach

Each method is introduced as a response to a specific gap, then it’s challenged from an adversarial perspective before continuing to the next approach.

Problem → Current solution → How it fails → Better approach → Remaining gap

Lesson Takeaways

By the end of the lesson, participants should be able to:

• Explain the purpose and core challenges of DNA synthesis screening.
• Compare several screening methodologies, including the assumptions, strengths, and limitations of each.
• Analyze how adversarial manipulation can expose weaknesses in screening approaches.
• Evaluate the current technological, operational, and policy gaps.

Prerequisites

A basic understanding of biosecurity is recommended, including familiarity with biological threats and misuse of biotechnology. No prior background in biology, artificial intelligence, or cybersecurity is required - these topics are introduced to the level needed for the lesson.

Estimated Duration

The lesson typically takes about 45 minutes without questions, but it is highly recommended to leave room for conversation.

About Me

My name is Idan, I work in cybersecurity and study biology in my spare time. DNA synthesis screening immediately caught my attention because it sits at the intersection of those two worlds: applying security thinking - adversarial behavior, and layered defenses - to biological systems. That unique connection of the fields led me to explore the topic and create this lesson.
