What is Cloud Security?

Cloud security — CSPM (Cloud Security Posture Management) in particular — told as a story about checking the locks on hundreds of rented sheds in the village, every day.

These days the boxes live in rented sheds outside the castle. Hundreds of them.The rented sheds are all over the village. Not inside the castle wall.

The shed owner looks after the walls and roof. Locking up is our job.But with hundreds of sheds, nobody knows who left a door open. In rented sheds, an unlocked door is a far more common accident than a broken wall.

A cloud security check is walking the lock-up list past every shed, every day.Is a door open, is a box visible from the road, are there too many keys? A machine walks it every morning, not a person. Anything wrong rings the bell on the spot.

The list is the same every day. And an open door can be shut by the machine itself.Too many keys goes to the roster office, boxes stay sealed, the log stays on. A badly locked door rings the guard room — or gets shut automatically.

The shed gatekeeper watches who comes and goes; the lock-up check looks at the shed itself.The outside-shed gatekeeper watches who carries what. The lock-up check looks at doors, keys, and where boxes sit. It takes both — and even then, a checklist can't stop a thief who breaks through the owner's wall.

In one breath

Cloud security (CSPM) = a machine walks the lock-up list past hundreds of rented sheds every day — open doors, boxes on the road, spare keys — and rings the bell or shuts the door itself. Their walls, our doors.

Continuously checks cloud account configuration — public storage, excessive IAM permissions, missing encryption, disabled logging — against policy, flags misconfigurations, and can auto-remediate. It covers our side of the shared responsibility model.

When grown-ups say it

CSPM
The lock-up checking machine. Walks the list past hundreds of rented sheds daily. Looks at doors, keys, and placement — not the boxes inside.
Shared responsibility model
Their walls, our doors. The owner guards walls, roof, and ground; we guard locks, keys, and boxes. Know where the line is first.
Misconfiguration
The unlocked door. Not a broken wall — a door we left open. Most rented-shed accidents are this.
Public bucket
A box left on the road. A box anyone in the village can open. The most common accident of all.
Excessive IAM permissions
Too many keys. Ten keys to one shed, and one goes missing. → the castle roster office
Versus CASB
The gatekeeper watches people; the check watches sheds. The gatekeeper watches who comes and goes with what; the check looks at the shed's own condition. → the outside-shed gatekeeper
Compliance check
The village rulebook. Each shed is held up against the village rules — what may not go where. Same list, every day.
Auto-remediation
The machine shuts the open door. Instead of ringing and waiting, known mistakes are fixed on the spot. A box on the road goes straight back inside.
