Why it matters
Model poisoning and compromised model updates can corrupt trusted AI from the inside, producing dangerous outputs that access controls alone cannot prevent—so defenders must govern model integrity, provenance, and runtime behavior, not just endpoint access.
An opinion piece by Kumar Mehta argues that model poisoning—via compromised training data, tampered embeddings, malicious fine-tunes, or corrupted model updates—is becoming the supply-chain problem of the AI era, and that enterprises defend the wrong layer by focusing only on access control. The article recommends a model gateway with runtime prompt/response inspection, centralized model access, version-controlled model updates with rollback, prompt-traffic anomaly monitoring, and controls on downstream actions driven by model outputs.
