If a user prefers to send data with encryption by logging in to a web-based system, which protocol should they access?

  • HTTP
  • SSH
  • DHCP
  • SNMP
  • POP
  • HTTPS
Explanation & Hint:

When sending data securely through a web-based system, the protocol you would want to use is HTTPS (Hypertext Transfer Protocol Secure). HTTPS is an extension of HTTP and is used for secure communication over a computer network, like the internet. It operates within the Transport Layer Security (TLS) or Secure Sockets Layer (SSL), which encrypts the data exchanged between a user’s browser and the web server. This encryption helps protect against eavesdroppers, man-in-the-middle attacks, and hijackers who might try to steal or alter the information being transmitted.

Here’s a brief overview of the other protocols mentioned and why they aren’t suitable for this specific case:

  • HTTP (Hypertext Transfer Protocol): HTTP is the foundation of data communication on the World Wide Web but does not include any encryption mechanisms. This means that data transmitted over HTTP can be intercepted and read by others.
  • SSH (Secure Shell): SSH is a cryptographic network protocol for operating network services securely over an unsecured network. While it provides secure data communication, it is typically used for logging into and executing commands on remote computers, not for secure web browsing or web-based system access.
  • DHCP (Dynamic Host Configuration Protocol): DHCP is a network management protocol used on IP networks whereby a server dynamically assigns IP addresses and other network configurations to devices, facilitating their ability to communicate on the network. It does not provide encryption or secure data transmission functionalities.
  • SNMP (Simple Network Management Protocol): SNMP is used for collecting information from, and configuring, network devices, such as routers and switches. It is not used for encrypting data or securing web communications.
  • POP (Post Office Protocol): POP is used by email clients to retrieve emails from a server. The latest version, POP3, can be secured with SSL/TLS, but it’s specific to email retrieval and not suitable for general secure web access or data transmission.

In summary, HTTPS is the correct protocol to use for securely logging in and sending data through a web-based system, as it encrypts the data to protect your privacy and security.
