LLM Infrastructure Security — Model Weights, Endpoints, Ops

Why it matters

LLM infrastructure is high-value target. Understanding shapes protection.

The architecture

Weights: encrypted at rest, access-controlled.

APIs: authenticated + rate-limited.

How it works end to end

Model theft: fine-tuned weights are valuable IP. Access control + audit.

Adversarial testing: red-team infra as well as model.

Ops access: least privilege + audit.

Data leaks: prompt + response logs contain sensitive info.
