+  "With tools like access control lists and firewalls, we engage in
+  'perimeter defense', which is more correctly described as 'eggshell
+  defense'. It is like an eggshell for the following reason: while an
+  eggshell may seem pretty tough when you tap on it, if you can get a
+  single pinhole anywhere in the surface, you can suck out the entire
+  yoke. No wonder cybercrackers laugh at our silly efforts to defend
+  ourselves. We have thrown away most of our chances to defend
+  ourselves before the battle even begins."
