What habits make browsing genuinely safer?

Learning objectives
  • State 10 safe-browsing rules
  • Explain what a VPN can and cannot do
  • Debate whether a VPN is always a good idea

Overview

Most malware infections start in a browser. Ten simple habits — combined with the tools from earlier lessons — block the majority of everyday attacks. VPNs are useful in some situations but are often oversold: they protect against local eavesdropping but do not make you anonymous or immune to phishing.

10 Safe-Browsing Rules

1) Keep browser updated. 2) Prefer HTTPS. 3) Do not click unknown links. 4) Check the URL bar. 5) Avoid pirated downloads. 6) Use an ad blocker. 7) Enable pop-up blocker. 8) Do not save passwords in shared browsers. 9) Log out after sessions on public devices. 10) Report suspicious sites.

What a VPN Does

Encrypts traffic between you and the VPN server; hides your IP from websites; useful on public Wi-Fi.

What a VPN Does Not Do

It does not stop phishing, malware, tracking cookies, or logins linking you to your accounts. The VPN provider itself sees your traffic — pick one you trust.
