10 Essential Internet Security Tips

Most attacks aren't sophisticated. They rely on a weak password, an out-of-date browser, or a convincing-looking email. Get these ten basics right and you've already avoided the vast majority of real-world threats.

1. Use a password manager

It solves two problems at once: long unique passwords for every account, and no more reuse across sites. A single leaked password stops being a disaster.

2. Turn on two-factor authentication

Start with email, banking, and anything tied to payment. Prefer an authenticator app or a hardware key over SMS.

3. Keep software updated

Browser, OS, phone apps — updates patch exactly the holes attackers look for. Turn on automatic updates and move on.

4. Run a modern antivirus

Behavioral detection catches what signature scanning misses. It's the safety net for when something slips past you.

5. Back up, and test your backups

The only reliable defense against ransomware. Keep at least one copy offline or in versioned cloud storage.

6. Lock down your email

Email is the recovery path for everything else. A strong password and 2FA on your main inbox matter more than almost anything.

7. Watch for phishing

Verify the sender, hover over links, and when in doubt navigate to the site directly instead of clicking.

8. Don't trust public Wi-Fi

Use a VPN on airports, cafes, and hotels — or tether to your phone.

9. Review app permissions

Every few months, check what your phone apps can access. Revoke anything that doesn't need the permission it has.

10. Slow down before you click

Urgency is the number-one phishing tactic. "Your account will be closed in 24 hours" is a red flag, not a deadline.
