What is the function of TCP Port 443 in the context of Tanium Cloud?

In the context of Tanium Cloud, TCP Port 443 is primarily used for secure communication, particularly for interactions that involve web traffic or API calls, which commonly employ HTTPS (HTTP Secure). This means it facilitates secure connections between clients and servers.

The correct choice highlights the critical nature of TCP Port 443 in downloading files, specifically in the context of communication between the Tanium client and a Content Delivery Network (CDN). CDNs are utilized to efficiently distribute and deliver content to users by caching files at various locations. By using TCP Port 443, Tanium Cloud ensures that the files transferred to the clients are done so over a secure connection, thereby protecting the integrity and confidentiality of the data being downloaded.

The other options do not accurately reflect the primary use of TCP Port 443 in Tanium Cloud. For instance, client-to-client communication typically occurs over different ports or protocols, whereas secure communication between Tanium servers may use other ports or does not solely rely on port 443. Lastly, asserting that TCP Port 443 is not used in Tanium Cloud is incorrect, as it plays an essential role in securing file downloads and interactions over the internet.
