Who opened the door?
A key can be copied. A key cannot say who used it. A card, a fingerprint or a PIN can.
Managed access checks who you are, lets you in and writes it down. In this lesson you also meet two rules for people at work: separate duties and role-based access.
Key words
| Word | What it means |
|---|---|
| Managed access | Letting only checked people in, and recording who came. |
| Card reader | A device that reads a staff card to open a door. |
| Biometric | A check that uses your body, such as a fingerprint or a face. |
| PIN | A short secret number you type in. |
| Passcode | A longer secret code you type in. |
| CCTV | Closed-circuit television: cameras that send video to screens or a recorder. |
| Separation of duties | Splitting a risky job between two people so one person cannot misuse it. |
| Role-based access | Giving a person only the access their job needs. |
| Network | Computers and devices joined together so they can share data. |
| Firewall | A filter that allows or blocks network traffic by rules. |

Cycle 1: managed access
Managed access mixes a physical door with a check. Four ways:
Card readers use something you have. A biometric check uses something you are. PINs and passcodes use something you know. Video, such as CCTV and a door camera, lets a guard see who is at the door.
Use two together, such as card and PIN, for a stronger door.
Four ways, compared
| Method | What it uses | Weak point |
|---|---|---|
| Card reader | Something you have | A card can be lost or lent |
| Biometric | Something you are | Can read you wrongly, and costs more |
| PIN or passcode | Something you know | Can be guessed or watched |
| Video | A person watching | Needs a person who is looking |
