The Layers — Why One Defence Is Never Enough

No single defence is perfect, so you use several — layers — and if one fails, the next holds. Learn to stack different kinds of layer, put the most around what matters most, count your people as a layer, distrust any single defence, and keep every layer working.

What you'll learn

• Understand why no single defence is perfect, so relying on one is relying on it never failing, and why the answer is layers.
• Grasp 'if one fails, the next holds', and build different kinds of layer that catch what the others miss.
• Count alert people as one of your strongest layers, and put the most protection around what matters most.
• Spot the 'we've got X, so we're covered' trap, ask 'what's behind it?', and keep every layer working.
