Reading Notes for Class 07, Self-Paced Ops 102

Objective

The objective of today's readings were to introduce us to the world of remotely connecting from one computer to another. The first article explains what happens on the backend when a user is trying to connect to an SSH server. The second article details how one would go about setting up remote connection on their Windows device. These readings will be helpful as we try to set up our own remote connections in the upcoming lab.

Reading Comprehension (1)

Title = SSH Protocol

  1. What is the Secure Shell (SSH) Protocol? The SSH Protocol is a method for secure remote login from one computer to another. It is a secure alternative to non-protected login protocols and insecure file transfer methods.
  2. What are the typical uses of the SSH protocol? Typical uses of the SSH protocol include (1) providing secure access for users and automated processes, (2) facilitating interactive and automated file transfers, (3) issuing remote commands, and (4) managing network infrastructure and other mission-critical system components.
  3. How does the SSH protocol work? The client will initiate the connection by first contacting the SSH server. The server will then send the client the server public key. The server and client then work together to negotiate parameters and open a secure channel for the client to client and server to exchange data in. Once set up, the client may then login to the server host operating system.
  4. How is the data kept safe when transmitted between the SSH client and server? The SSH protocol uses strong symmetric encryption and hashing algorithms to ensure the privacy and integrity of the data that is exchanged.
  5. What is SFTP? SSH File Transfer Protocol. It is the most widely used secure file transfer protocol that exists today.

Things I'd like to know more about (1)

  • I wonder exactly how the encryption of the client's data works. How does one even go about designing something like that?

Reading Comprehension (2)

Title = What is RDP? And how to use it

  1. What is Windows Remote Desktop Connection? This tool gives users the ability to connect to a remote Windows PC or server over the internet or on a local network, allowing them to gain full access to the tools and software installed on it.
  2. What is RDP? Remote Desktop Protocol. This protocol allows remote users to see and use Windows on a device in another location.
  3. What is the RDP port number? port 3389
