Web Protocol Security (HTTP vs HTTPS):
A user fills out an online form to enter their credentials on a web page.
Answer the following questions:
1. What happens to the transmitted data if the website uses the HTTP protocol and an attacker intercepts the traffic (sniffing)?
2. How does the HTTPS protocol solve this problem and what technologies/standards does it use to support it?
3. Which standard port is used by HTTP and which by HTTPS?
Analisi: Guide the student to reflect on cleartext vs. encrypted transmission. Ask: 'If data travels in cleartext, can anyone on the path read it? What is the role of SSL/TLS certificates in HTTPS?'. Discuss asymmetric cryptography for negotiation and symmetric cryptography for data exchange.
