In this module, you learned about a foundational organizing principle in networking: layers of communication. The OSI model and the TCP$/$IP model are both commonly used to guide network design, maintenance, and troubleshooting tasks.

This text gave the analogy of a letter being mailed via the post office to illustrate the nature of each layer in the OSI model. Many other analogies can be used to further describe how communications layers function in a system. What examples can you HLP Ltd$.$ has already set up a private web server for its corporate network with Windows as an operating system, and now they have contacted you to make their network remotely accessible to a certain group of employees. They have also requested you to ensure that the selected protocol provides secured and encrypted transmissions.

Which of the following protocols would you apply so that the employees can have secured remote access to the computer server?
