The lesson

HTTPS encrypts the connection between your browser and a site, so others on the network cannot read it. The padlock does not prove the site is honest — fake sites use HTTPS too.

Check the domain name carefully: look-alike domains swap letters or add words. Go to important sites by typing the address or using a bookmark.

Download software only from official sources; avoid 'cracked' software, which often carries malware.

Step by step

  1. Compare genuine and look-alike domains.
  2. Check a site's padlock and address.
  3. Bookmark important sites.
  4. Find the official download page for a common app.

Practice activity

Bookmark your bank, email and government sites and write three download rules.

Expected result: Safe bookmarks and clear download rules.
