Safe Browsing & Data Privacy Basics

In this lesson you will

  • Judge websites and downloads
  • Tighten privacy settings

How and where you browse affects how exposed your data is — public Wi-Fi, oversharing on social media, and unclear privacy settings are common everyday risks.

  • HTTPS: Look for the padlock icon and "https://" before entering any sensitive information on a website — it means the connection is encrypted.
  • Public Wi-Fi: Avoid logging into banking or sensitive accounts on public/shared Wi-Fi where possible; it's easier for others on the same network to intercept traffic.
  • Social media privacy: Review who can see your posts, location tags, and personal details — oversharing (travel plans, daily routines) can create real-world safety risks.
  • Data minimization: Only share the personal information a service genuinely needs — question requests for excessive detail.

Practical Skill: Review your main social media account's privacy settings and adjust who can see your posts, contact details, and location information.

Worksheet
=== SOCIAL MEDIA PRIVACY REVIEW === [ ] Who can see your posts? (Public / Friends / Custom)[ ] Is your phone number visible to the public?[ ] Is location tagging on for your posts? Turn it off unless needed.[ ] Do old posts reveal your daily routine or travel plans?[ ] Is your profile photo/bio revealing more than necessary? === BEFORE ENTERING SENSITIVE INFO ONLINE ===[ ] Does the address bar show "https://" and a padlock icon?[ ] Are you on a trusted network (not open public Wi-Fi)?[ ] Does the website's name match exactly what you expected    (watch for lookalike spellings)?

Practice exercise

Bookmark your bank and email sites, turn off automatic joining of open Wi-Fi and review one social media account's privacy settings.

Key takeaways

  • The padlock means encrypted, not trustworthy
  • Prefer mobile data for sensitive tasks
  • Share less personal information publicly
