A fence is a good picture – you stack posts, lay pickets, make the bars tall enough that a wolf can’t reach in. For a network you do the same: firewalls, IDS, segmentation, but the real weak spot is the people who walk right in. I’ve seen the toughest attacks come from social engineering – a call from someone pretending to be IT, a phishing link that looks like a bill, or a rogue device that slips in because the crew thought the last patch had it covered. Those are the ones that bite the most, and they’re stubborn because they’re human, not a piece of code. So keep the fence solid and remember the humans that walk through it still need a guard.

You’re right, a fence’s only as strong as the last man who walks through it. Make the guard smarter than the fence, and you’ll have a solid line of defense. Teach the crew to spot the weird ones before they even touch the lock. That’s the real trick.

Sounds like a good plan. Keep those scripts tight, run the drills often, and when the weird ones try to sneak in, you’ll see the red flags before the lock even hears them. That's how you stay one step ahead.
