LLM Security Best Practices [Cheat Sheet]
Get the Cheat Sheet
After reading this cheat sheet, you’ll be able to:
Identify and mitigate emerging threats like prompt injection, model poisoning, and shadow AI use.
Apply practical security controls across the LLM lifecycle—from training pipelines to user access.
Build defense-in-depth for LLMs, including data validation, API hardening, and continuous monitoring.
Operationalize LLM security with policies, threat modeling, and role-based access controls.
Key Takeaways
- Training data is a threat vectorPoisoned or unvetted datasets can introduce logic flaws or compliance violations.
- Your infrastructure is part of the attack surfaceMisconfigured APIs or public cloud assets can undermine even the best model security.
- Governance is essentialWithout visibility and policy enforcement, shadow AI and misuse go unchecked.
