Security Is About Reducing Blast Radius

You can’t prevent every failure.
You can control how bad it gets.

Good security assumes compromise and asks:
What can this access?
How far does it spread?
How fast can we recover?

That’s why isolation, least privilege, and monitoring matter.
They limit damage, not just entry.

Perfect defense is a myth.
Resilience isn’t.

Security is about containment, not invincibility.
