While AI can dramatically accelerate security review of IaC, unchecked hallucinations render many solutions worse than useless. This talk demonstrates practical techniques for building trustworthy AI systems that can reliably analyze Terraform and CDK code for misconfigurations and vulnerabilities. Through live demonstrations of hallucination detection, output validation, and claim verification pipelines, attendees will learn how to build safeguards to use AI as a dependable cloud security tool. We'll examine where the "hallucination hotspots" lie, how to leverage open-source libraries and prompting to prevent them, and how to generate actionable remediation plans that actually work in real-world cloud environments.
