ITPEC FE Morning October 2021 Question 44
ITPEC FE Morning October 2021 — Question 44 of 80
TLS for Web Traffic Protection — TLS encrypts data between a browser and a web service over public networks.
The question asks which technology protects credit card data transferred between a customer's PC and a web service over public networks.
Answer: c) TLS
- •TLS (Transport Layer Security) is the protocol behind HTTPS
- •It encrypts the communication channel between a web browser and a web server
- •Standard solution for protecting sensitive data (credit cards, passwords) in transit
Why not others:
- (a) S/MIME — encrypts email content, not web traffic
- (b) SSH — provides secure remote shell/terminal access, not browser-to-server encryption
- (d) VPN — encrypts all network traffic between two endpoints; not a technology a web service deploys for its customers
Key rule: Browser ↔ Web server encryption over public networks = TLS (HTTPS).
