What it is
Why it matters
We bank, shop, chat, and work online. One weak password or fake link can open the door to identity theft, drained accounts, or a locked-up laptop. Good security turns those “uh-oh” moments into non-events.
How it works (people + process + tech)
-
People: learn to spot phish, use strong passwords, and confirm money/account changes.
-
Process: simple rules—updates on, backups running, MFA required.
-
Tech: firewalls, anti-malware/EDR, password managers, DNS filtering, and encryption.
Common risks in real life
-
Phishing & fake sites that steal logins
-
Weak/reused passwords that unlock many accounts
-
Unpatched devices with exploitable bugs
-
Ransomware & info-stealers hidden in “free” downloads
Quick wins (5-minute checklist)
-
Turn on MFA everywhere (prefer an app or security key).
-
Use a password manager and unique passwords.
-
Keep devices, browsers, and apps updated.
-
Back up important files offline or immutable.
-
Be skeptical of urgent messages—verify out of band before paying or sharing.
