Question
A web server is configured to only allow secure connections. Which of the following will a user most likely use to connect to the web server?
A. TFTP
B. HTTP
C. FTP
D. TLS
Answer
D. TLS (Transport Layer Security)
Explanation
When a web server is configured to only allow secure connections, it means that all traffic between the client (web browser) and the server must be encrypted. This ensures the confidentiality and integrity of the data being transmitted.
TLS is the protocol used to establish secure, encrypted connections between clients and servers over the internet. It is the successor to the older SSL (Secure Sockets Layer) protocol.
When a client initiates a connection to a web server that requires secure connections, the client and server perform a TLS handshake. During this process, they negotiate the encryption algorithms to use, verify each other’s identities using digital certificates, and establish a shared session key to encrypt the data. Once the TLS handshake is complete, all subsequent traffic is encrypted.
The other options are incorrect because:
A. TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that does not support encryption.
B. HTTP (Hypertext Transfer Protocol) is used for transmitting web pages, but it sends data in plain text and does not provide encryption.
C. FTP (File Transfer Protocol) is used for transferring files, but like HTTP, it does not natively support encryption.
So in summary, TLS is the protocol that enables secure, encrypted connections between clients and web servers configured to require secure connections. It is an essential technology for protecting sensitive data transmitted over the internet.
