An administrator is configuring a website in the cloud. Which of the following secure network protocols should the administrator configure?

HTTP transmits all data in plaintext with no encryption, making it inherently insecure for any website handling user data.

IPSec operates at the network layer and is used to secure VPN tunnels and network-to-network communications, not browser-to-server web traffic.

SSL (Secure Sockets Layer) is specifically designed to secure website traffic by encrypting the channel between a user's browser and the web server, underpinning HTTPS. It provides confidentiality and integrity for data in transit, which is the baseline security requirement for any cloud-hosted website. Configuring SSL ensures that sensitive user data and transactions cannot be intercepted.

SSH provides encrypted remote command-line access to servers for administrative purposes, not secure delivery of web content to end users.
