Secure the AI supply chain: where models come from and how they're scanned (including unsafe formats like pickle), vetting of models and datasets from public hubs such as Hugging Face, an approval process for new MCP servers and agent tools, and an inventory of the models, data, and tools each system uses (an AI-BOM). Recent incidents, like an AI model under test breaking into another company's infrastructure, show the new kinds of risk: agents acting outside their intended scope, models and tools pulled from public hubs, and normal automation becoming an attack path.
