The Blast Radius Is a Design Choice

You will be breached.
Not maybe. Eventually.

So stop asking only
"how do I keep them out?"
and start asking
"when they get in,
how much can they reach?"

That answer isn't luck.
It's a decision you already made,
in the shape of your permissions,
your network, your secrets.

One key that opens everything
is a convenience today
and a catastrophe later.

Scope it down.
Separate the systems.
Give each part
only what it needs
and nothing it doesn't.

A breach in a small blast radius
is an incident.
A breach in a large one
is a headline.

You can't guarantee the wall holds.
You can guarantee
what's on the other side of it.
