The most common form of securing channels is through ________.

Solution (By Examveda Team)

The correct answer is C: SSL. Here's why:

SSL (Secure Sockets Layer) is the most widely used protocol for securing communication channels on the internet.
It creates an encrypted connection between a web server and a browser, ensuring that all data transmitted is private and secure.
You'll often see "HTTPS" (HTTP Secure) in the URL, which indicates that SSL/TLS is being used.

Let's look at the other options:

A: S-HTTP (Secure HTTP) is an older protocol, less commonly used than SSL/TLS.
It focuses on securing individual messages rather than the entire connection.

B: VPNs (Virtual Private Networks) create a secure connection to a private network.
While they provide security, they are more often used for securing access to a network rather than specifically securing eCommerce transactions directly on websites.

D: PPTP (Point-to-Point Tunneling Protocol) is an older VPN protocol that has known security vulnerabilities.
It is generally not recommended for secure communications anymore.

Therefore, because of its widespread adoption and specific focus on securing web communication, SSL is the most common form of securing eCommerce channels.
