Chapters
- Always look for a padlock icon in the browser's address bar.
- The padlock indicates that your connection to the website is secure and encrypted.
- If there is no padlock, your data is transmitted openly and is not safe from interception.
This is the most immediate visual cue to determine if a website is protecting your sensitive information during transmission.
Seeing a padlock next to the website address in your browser.
- Be vigilant about fake websites designed to mimic legitimate ones.
- Carefully check the website's URL (web address) for any discrepancies.
- A slightly altered URL can indicate a fraudulent site trying to trick you.
Fake websites can steal your login credentials or personal information, so verifying the URL is crucial before entering any data.
A fake website might have a URL like 'amaz0n.com' instead of 'amazon.com'.
- Public Wi-Fi networks, like those in cafes or airports, are often unsecured.
- When connected to public Wi-Fi, others on the same network might be able to monitor your internet activity.
- While individual websites can use encryption (HTTPS) to protect your data, the network itself is a potential vulnerability.
Unsecured public Wi-Fi exposes your online activities to potential eavesdroppers, making it risky for sensitive transactions.
Using free Wi-Fi at an airport where someone else on the network could potentially see the websites you visit.
- A 'not secure' warning in the address bar means the website is not using encryption.
- Data sent to or from a 'not secure' site is transmitted in plain text.
- This makes your information vulnerable to being read by anyone intercepting the traffic.
This warning is a direct signal that your data is unprotected, and you should avoid entering any sensitive information on such sites.

Key takeaways
- Always prioritize websites with a visible padlock icon for secure connections.
- Scrutinize website URLs to prevent falling victim to phishing or fake sites.
- Be extremely cautious when using public Wi-Fi, as your activity can be monitored.
- A 'not secure' warning indicates that your data is exposed and should not be shared.
- Website encryption (HTTPS) protects data between you and the site, but not necessarily the network you're on.
