Which port would be used to secure e-commerce transactions across the web?
25
80
443
22
Correct Answer: 443. TCP port 443 used to secure web browser communication (e.g., online shopping and banking). Edit: Remember TCP/443 is HTTPS or HTTP over SSL(Secure Socket Layer)/TLS(Transport Layer Security). TCP/22 or SSH(Secure Shell) is used for secure remote connectivity between clients. While true that SSH provides security for file transfer, we are talking about an e-commerce "website" so port 443 would be the correct answer here. TCP/80 is HTTP (unsecured) and TCP/25 is SMTP(Simple Mail Transfer Protocol).
