THE EXAMS POINT / COMPUTER AWARENESS

Digital security: protect the account and the data

01 · Authentication

Establish who is trying to access the system.

02 · Authorisation

Limit what an authenticated user is allowed to do.

03 · Phishing awareness

Check the actual domain and request; avoid sharing passwords or OTPs.

04 · Strong access protection

Use unique passwords and supported multi-factor authentication.

05 · Updates and backups

Patch known weaknesses and keep recoverable copies of important data.

Connect the branches

Security uses multiple controls. No single password, antivirus or certificate guarantees safety.

Avoid the exam trap

HTTPS encrypts a connection; it does not prove every claim on a website is trustworthy.

Test yourself: Is signing in successfully enough to access every other user’s records?

No. Authorisation must enforce which records and actions that user may access.

A concise revision aid with simplified connections. It supports the full chapter and primary references; it does not replace them.
