One burglar, many rooms
A thief gets into a shop through the back door. If the shop is one big room, he reaches everything. If every room has its own lock, he gets only one.
Three controls in this lesson work the same way: split things up, protect the machines, and check who is at the door.

Note
I can explain segmentation, hardware protection and multi-factor login, and what risk each lowers.
Key words
| Word | What it means | Example |
|---|---|---|
| Segmentation | splitting a network, systems, data, devices or services into separate parts | |
| Network | computers and devices linked so they can share data | |
| Multi-factor login (MFA) | proving who you are in two or more different ways | |
| Factor | one way of proving who you are | A password, a phone, a fingerprint |
| Hardware protection | using server and software solutions to protect machines and the data on them | |
| Redundancy | a spare part that takes over when the first one fails | |
| Encryption | scrambling data so only the right key can read it |
The cells students fill in are left blank in this preview.

Segmentation: split it up
With segmentation you split the network, systems, data, devices and services into separate parts. Each part has its own rules.
If an attacker or a harmful program gets into one part, it is stopped at the wall. The impact is smaller. This lowers the impact of the risk.
