Defense in Depth: A Sanity Check

Defense in depth means multiple layers. Audit yours.

Layers

Network, identity, app, data. Each independent.

No single point of failure.

Audit

For each layer: what's the control? Tested?

Per-layer verification.

Gaps

Single-layer protection is fragile. Add layers where missing.

Defense in depth real, not theatrical.
