Magical "Security"

When your security practices are informed by magical thinking, even children will find a way around your protective measures.

Never underestimate your adversary

I'm not calling capybaras the enemy, but if you're trying to keep them in an enclosure and they're working against you then adversary definitely seems like the appropriate classification

Not all bypass tools are created equal

It's actually just street art, but the implication that you can bypass the locked gate by jumping over it seems to be intended. Also it does demonstrate a real phenomenon about bypass tools - some are better than others. Sometimes they're a lot better or a lot worse.

Keeping honest people honest

It's been said that locks merely keep honest people honest, but I disagree. Most people wouldn't have the first clue how to pick, bump, or otherwise bypass a lock. It's not stopping them because they're honest, it's stopping them because they don't know how to overcome it. 

Everyone knows how to go around and obstacle, however. This is what keeping honest people honest really looks like.

Never underestimate your adversary

I don't know, maybe if the gate was on the other side of the door the dog might not have been able to tear the door apart. Another possiblity might be one of those metal kick plates for the far side of the door, since the dog probably started tearing at the bottom and the metal should help prevent that. The key point, though, is to be aware of what kind of attack your defenses are likely to face, evaluate them on whether they are up to the task, and add additional layers to address weaknesses.

Seems Compliant

So long as you've got the approved access controls in place, you're all good. Who cares if the controls are effective, that's not what compliance measures. It doesn't matter that anyone who can navigate stairs can also navigate around this obstacle.

A gate is only as strong as it's weakest lock

found on Acid Cow

You've heard the saying that a chain is only as strong as it's weakest link? Well as this multi-user access gate demonstrates, something similar can be said of gates and locks. Of course most gates only have 1 lock so you might not even think of it in those cases, but even then it's still true (trivially so in fact).

Not that useless

 You could go over. You could go around. There's a number of very easy ways to bypass this security. 

Safe OR Secure?

Usually you don't have to choose between the two, unless someone does something really ill-advised like this.

A different kind of escalation vulnerability

found on Dump A Day

I suspect you don't actually have to climb this to get past it. It looks like you could just reach through the bars and unlock it from the other side.

NPCs won't stand a chance

What about the people who follow the paved path, you say? They would still need to turn in order to operate and enter the door. This would literally only stop the people who have to come at the door head on and can't avoid this very narrow barrier

Are we living in a simulation?

I certainly hope they have another layer of security somewhere, because that gate isn't stopping anyone.

Why security measures often fail

 Now if your security measures are such that the wrong paths have less resistance than the right paths, then that's something you need to improve.

It's Brobdingnagian

I feel confident that that gate will keep people out (or in) pretty effectively. How would you open it?

You shall not pass

Go ahead and try to unlock that without disturbing the nest. I dare you.

How to keep out giants

I don't see any giants around there so I guess it must be working.

Hopefully that's the threat model

Never in a million years would I have expected to see someone stopped by a solitary gate.
