Windows server 2012 Practice Test

The choice of SSL (Secure Sockets Layer) as the correct answer highlights its role in establishing secure communication over the internet. SSL is a protocol that provides encryption, ensuring that data transmitted between a client and a server remains confidential and protected from eavesdropping. This is particularly important in scenarios where sensitive information, such as credit card numbers or personal data, is transmitted.

Firewalls often need to allow or deny traffic based on certain rules, and the ability to configure these rules for SSL is a critical aspect of network security. When SSL is employed, it typically operates over the HTTP protocol, forming HTTPS (HTTP Secure), which is widely used for secure transactions on the web. Thus, configuring firewall rules to allow or restrict HTTPS traffic directly relates to SSL.

The other protocols mentioned serve different functions and do not provide secure communication inherently. FTP (File Transfer Protocol) is used for transferring files but lacks encryption by default. HTTP (Hypertext Transfer Protocol) is the standard for web traffic but also does not include security features. Telnet is used for remote access to servers but transmits data, including credentials, in plaintext, making it vulnerable to interception. This highlights why SSL is the appropriate choice for ensuring secure communications that can be governed by firewall rules
