Stage 1 · Lesson 7 of 7
Secure defaults and layers
means stacking independent layers so one failure does not become a breach. For AI features this is not optional, because some layers, such as model-based guards, fail a measurable share of the time. A good default stack for a new AI feature: authentication on every request, data access scoped to the user in code, , output encoding, a guard or two, limits on size, rate and spend, logging, and an easy way to switch the feature off.
Defaults matter because most teams never revisit them: ship the safe setting and make the risky one an explicit, reviewed choice.
Common trapadding one impressive control, such as a product, and leaving the other layers empty because the demo looks safe.
