Security Koan #3
The security guard phoned his boss in a panic.
"There's been a break-in to the site, sir. The intruders aren't anywhere to be seen, but they've got away with a bunch of equipment."
"Understood - go and look at the perimeter fence, find out where they broke in, and keep watch. I'll be there shortly."
The boss arrived at the site, to find the guard pacing up and down in front of the fence.
"Did you find the hole yet?" asked the boss.
"Not yet, sir."
"Never mind, I'll help you look."
For the next half-hour, they went up and down, searching for a hole in the fence.
Then the boss spoke up:
"Are you sure this is where they got in?"
"No, they got in on the other side of the site."
"Then why are you looking over on this side?"
"Because the light's better here, so we can see more."
Question: Are you monitoring the places most suited for attack, or simply the places easiest to monitor?
