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.
