Remote network access overview

Companies increasingly require the capacity to access resources—whether apps, files, servers, or other resources—across a network. Employees now also need this ability to accesswork files from anywhere. This skill, called remote network access or remote access, has become immensely more significant nowadays.

This post will cover remote network access definition, protocols, and types. Moreover, we will discuss network-based remote access tools. Let’s get going.

Remote Network Access

What is remote network access?

Remote network access refers to accessing various network resources, such as files, applications, desktops, and servers. The network comprises the local area network (LAN) and the wide area network (WAN). With remote network access, users can access resources and perform computer-related tasks anywhere, even worldwide.

How does remote network access work?

Remote network access works through alot of components. When a user access data or launch a remote desktop, all the members operate on software, hardware, and the network to function.

How Does Remote Network Access Work

6 common types of remote network access protocols

Performing remote network access may apply one or more remote network access protocols. Let’s talk about the most common ones.

Remote Network Access Protocols

Point-to-Point Protocol (PPP)

PPP is a direct communication protocol. It can operate via various network communications channels, such as phone lines, serial cables, cellular networks, fiber optic lines, SONET, ISDN, and others.

PPP enables the communication between two computer systems situated in different locations. It can also be utilized by an Internet Service Provider (ISP) to send IP packets between two modems.

Point-to-Point Tunneling Protocol (PPTP)

PPTP is a remote network access protocol based on PPP that is used for VPNs. It is not suggested for businesses because it does not provide encryption or authentication.

Internet Protocol Security (IPSec)

IPSec is a set of security protocols that safeguard data transfer over public networks such as the Internet. It supports features like encryption, data integrity, and authentication. It secures the VPN connection for remote device access and is frequently used with VPN tunneling protocols like L2TP.

IPSec can be incredibly secure if properly configured but also quite complicated. For example, workarounds are required to make it compatible with a NAT firewall. If you are going to deploy an IPSec-enabled solution in business, we recommend testing for interoperability with the current solutions you wish to apply with it.

Remote Desktop Protocol (RDP)

RDP protocol makes it possible to access a Windows system remotely. Remote workers frequently use it to access files and applications on their work PCs. Also, tech support employees often use it to establish a Remote Desktop Connection to troubleshoot end-user devices.

RDP has several functions. You can control a remote device as if you were physically using it. You can also copy and paste content between remote and local sessions, print on local printers from a remote session, etc.

RDP Introduction

Layer Two Tunneling Protocol (L2TP)

L2TP is also used for VPNs, similar to PPTP. It is significantly more secure than PPTP since it encrypts the control data. It does not, however, encrypt the content itself. It is typically combined with IPSec since it offers the necessary security.

Serial Line Internet Protocol (SLIP)

SLIPis an old UNIX protocol that is still commonly used today. It can transmit TCP/IP over serial connections. However, it limits in terms of advanced features like error checking and packet addressing. For this reason, alternative protocols have supplanted it and made it obsolete.

3 common types of remote network access

The following three different types of remote access are in widespread use today.

Remote access to desktops

Remote access to desktops refers to accessing any operating system running on a distant device. With remote access, for example, a user in London can interact with a PC in Paris as if it were running locally.

To remotely access a desktop over the Internet, you can use the Windows RDP protocol or third-party remote desktop software.

What is Remote Access

Remote access to applications

Remote access to applications is similar to remote access to desktops. However, the user only accesses a single application rather than the entire desktop. For example, users can set up RemoteApp to remotely control Windows-based apps without taking control of the computer.

Remote access to files

Remote access to files is widely used in businesses. Not every business requires remote access to applications or desktops. You may occasionally want to access work files only. In this case, a VPN solution is preferable to RDP or other solutions. This is because VPNs provide secure connections for remote network access to files, even when done via the Internet.
