Understanding Remote Access Protocols

Remote access protocols make everyone’s jobs easier by enabling technicians to troubleshoot remote devices. They also allow organizations to collaborate, even with fully remote or hybrid workforces.

For remote access to work properly, organizations connect their remote servers to endpoints using remote access protocols. Let’s explore these protocols and learn how they are used in today’s tech environments.

What are Remote Access Protocols?

Remote access protocols control the connections between remote access servers and endpoints. These protocols allow technicians to safely access endpoints from a remote location. Although the main purpose of remote access is technical support and help-desk activities, it can also be used to share documents and files between various devices.

Remote Access Protocols List: 8 Remote Access You Should Know

Understanding the various remote access protocols helps organizations choose the right remote access solutions for their teams. However, it isn’t necessary to know all the remote access protocols, just the most relevant ones.

1) Serial line internet protocol (SLIP)

Serial line internet protocol (SLIP) was a remote access protocol developed for UNIX back in the 1980s that’s still widely used today. The purpose of SLIP is to transmit TCP/IP only over serial connections. IBM’s SLIP guide provides excellent resources for configuring, activating, deactivating, and troubleshooting for SLIP.

2) Point-to-point protocol (PPP)

Point-to-point protocol (PPP) enables technicians to use TCP/IP. PPP can be used for both dial-in and dial-out servers. When choosing between PPP and SLIP protocols for your organization, keep in mind that PPP is often the better choice due to its support for multilink connections and better authentication abilities.

3) Point-to-point protocol over ethernet (PPPoE)

Point-to-point protocol over ethernet (PPPoE) offers the same benefits as PPP over ethernet networks. PPPoE allowss service providers to manage multi-client envrionments, authenticate users access, and monitor data usage. In addition, this remote access protocol supports data encryption and compression.

4) Secure Shell (SSH)

SSH Secure Shell (SSH) is a remote access protocol that enables secure, encrypted communication between devices over an unsecured network. IT professionals can use SSH to remotely access and manage servers, network devices, and other systems with command-line interfaces. Strong authentication methods, such as encryption, protect servers against unauthorized access.

5) Virtual Private Networks (VPNs)

A Virtual Private Network (VPN) is a remote access protocol that establishes an encrypted connection between a device and a private network over the internet. A VPN masks the user’s IP address and encrypts all data. Businesses typically utilize VPNs to allow users to access corporate resources, applications, and files remotely.

6) Point-to-point tunneling protocol (PPTP)

Point-to-point tunneling protocol (PPTP) was developed by Microsoft and is based on PPP. PPTP uses PPP and TCP/IP to create secure, virtual connections across networks. PPTP works by using connections, often referred to as “tunnels,” that are encrypted to send network data packets to servers. Once the servers receive the packets, they send the data packets to their destinations.

7) Windows remote access service (RAS)

Windows remote access service (RAS) is used for smaller networks that don’t require a dial-up router. It allows technicians to dial-up and connect to a server and the server’s network. Network Encyclopedia’s RAS review explains, “RAS allows remote clients to connect through a telephone line or other wide area network (WAN) link to the RAS server; from there RAS allows those clients to access resources on the network. Remote users can access network resources as though they were logged on to a machine directly connected to the network.”

8) Remote desktop protocol (RDP)

Remote desktop protocol (RDP) from Microsoft allows technicians to securely access and control other devices. Although RDP is mainly used for Windows OS, it can also be used for macOS. The way RDP works is by opening a network channel that sends data back and forth between the desktop and the other computer that is being used. All essential data (keystrokes, displays, mouse movements, et cetera) is transmitted via TCP/IP.

The Importance of Remote Access Protocols

Now that you have a better understanding of remote access protocols, you’ll be better prepared to choose the best remote access solution for your organization. You can ensure that the remote access solution you choose uses secure protocols and keeps information safe. All of the protocols listed above support remote and hybrid workforces by allowing technicians to provide remote aid while keeping endpoints and data secure.
