Defense in Depth
A security architecture design principle that enhances overall system security by constructing multiple mutually independent protective layers, thereby preventing a single point of failure from causing the collapse of the entire defensive perimeter.
Timeline (last 90 days)
A common layered defense in practice: the first layer is zero-cost hash filtering, the second layer uses embeddings to catch what slips through, and the third layer brings in humans when costs spiral out of control.
The core objective of layered defense is to prevent a bad output from turning into a bad action, thereby reducing the blast radius of a single error.
Making absolute guarantees about system isolation is extremely difficult, which is why layered defense is very important.
