Answer Key

What cyber security is

Section A: Quick Questions

A — Protecting digital systems, accounts and data from attack and unauthorised access

B — Turning on multi-factor authentication for your login

A — Encrypting a file so only people with the key can read it

B — Installing updates and antivirus software on your laptop

A — False - it matters to everyone who uses accounts, data or devices

Section B: Match the Pairs

cyber security → The protection of digital systems, accounts and data from attack, damage and unauthorised access.

protect(device) → Keeping a phone or laptop safe from attack, for example with antivirus software and updates.

Protecting an account means making it hard for anyone else to log in as you. → account.protect = strongPassphrase + MFA

Protecting data means keeping files safe from theft or damage, and unreadable to outsiders. → data = encrypt(data)

cyber security = only antivirus on a laptop → This is too narrow. Cyber security protects accounts, data and devices, not just one device with one tool.

cyber security = deleting all your files → Cyber security is about keeping data safe from attack, damage and unauthorised access, not removing it.

Section C: Definitions

cyber security — The protection of digital systems, accounts and data from attack, damage and unauthorised access, such as keeping accounts, files and devices safe.

Section D: Fill in the Blanks

protect(accounts, data, devices)

IF user IS NOT allowed THEN
    deny(access)

Section E: Spot the Error

C — An if statement must end with a colon. The line should be: if mfa_on and password_strong: so the account protection check runs.

C — To protect data from being read, you encrypt it. decrypt turns scrambled data back into readable data, so the line should use encrypt.

B — Python's Boolean value must be written with a capital T. The line should be: updates = True

D — The text being returned must be inside quotes. The line should be: return 'At risk' so it is a string, not two unknown names.

A — Python uses the keyword def to define a function, not function. The line should be: def lock_account(user):
