Web Security · Junior · Question 15 of 75
Why do browsers show a full-page warning for an invalid or self-signed certificate?
- 1Because the site uses an outdated version of HTML
- 2Because the certificate is too large to download
- ✓Correct answer: The browser can't confirm it's talking to the real server, so the connection could be intercepted
Explanation
A certificate binds a domain to a key, signed by a trusted authority. Clicking through the warning removes the protection HTTPS is supposed to give.
