What is Remote Access Technology?
Remote access technology refers to any IT toolset used to connect to, access, and control devices, resources, and data stored on a local network from a remote geographic location. This is different from using a cloud solution, as it provides access to an on-premises environment rather than being hosted offsite in a shared environment and available via the internet. This makes remote access crucial for businesses of all sizes which have not moved to a cloud-first model, or which require access to on-premises machines or resources. Three of the most common remote access technologies – Remote Desktop Services, Remote Access Software, and Virtual Private Networks – are examined in detail in this article.
What Is Remote Access Software?
Remote Access Software offers an alternative to RDS and leverages a dedicated software to remotely connect users to an endpoint device from anywhere in the world via the internet. This method of remote access is typically the easiest to implement, as it only requires the user to install the software on the computer to be accessed. This type of remote access is especially useful when most of the organization’s endpoint devices are desktops.
What Is a Virtual Private Network?
A Virtual Private Network (VPN) is a technology which creates a smaller, private network on top of a larger public network – most commonly the internet. By logging into the VPN, users can gain internet-based access to applications that would otherwise only work on local networks. The goal of any client-based VPN solution is to provide remote employees with the same level of access as onsite. However, this is functionally different from an RDS session, as it does not allow full access to an entire desktop, but only specific applications, software, and other resources which the user has been given access to.
What is remote desktop service?
Remote Desktop Services (RDS), also known as Terminal Services, is one of the most common methods used by SMBs to enable remote work. By using RDS, individuals can remotely connect to an endpoint device or server which supports Remote Desktop Protocol (RDP) via a Terminal Server. The connection can be made over a local network or internet connection and gives the user full access to the tools and software installed on the machine they connect to. This method is frequently used by IT departments to remotely access servers, or to provide easy local software access to multiple employees.
Why do organizations use VPN?
Organizations of all sizes frequently use VPN technology to securely access remote resources from multiple locations. Unlike RDS, VPN connectivity does not require additional dedicated hardware to function securely over the internet and is designed to be particularly secure. Most VPN connections are encrypted using either Secure Sockets Layer (SSL) or Transport Layer Security (TSL) to ensure that the data cannot be read by malicious third parties.
What is the most common application used with RDS?
One common business application which is frequently used with RDS is Intuit Quickbooks. Many companies install the application on a central Terminal Server instead of individual computers, allowing multiple users to connect to the software on a remote device via RDS and access the toolset.

What is virtual private network?
Virtual private networking protocols encapsulate PPP frames (the data units at the data link layer of the OSI model) into IP datagrams at the network layer. These datagrams are then sent across an internetwork, which can be either a private network or, more commonly, the Internet. This encapsulation creates a “tunnel” that acts like a dedicated WAN link, even though it usually uses the Internet—thus, a “virtual” private network.
Why do you want to be encrypted in a remote session?
First, you want the best security you can provide for the remote session. You want authentication to be encrypted so that someone who is snooping cannot see it , and you want the data that is passed in the remote session to be encrypted for the same reason. Second, older systems and their associated protocols are less capable in terms ...
What is dial up modem?
Dial-up involves one modem connecting with another over the Public Switched Telephone Network (PSTN), creating a temporary, dedicated WAN link. There are three possible protocols for making the initial connection: Point-to-Point Protocol (PPP), Serial Line Internet Protocol (SLIP), and Asynchronous NetBEUI (AsyBEUI). Table A explains their differences.
Why is SLIP needed in NT?
Serial Line Internet Protocol (SLIP) SLIP is used as a client in NT or Win2K only when necessary to connect to an older server that is not supporting PPP.
How to use PPTP?
To use PPTP, you set up a PPP session between the client and server, typically over the Internet. Once the session is established, you create a second dial-up session that dials through the existing PPP session using PPTP. The PPTP session tunnels through the existing PPP connection, creating a secure session.
What is LCP in PPP?
LCP tests the link between client and PPP host and specifies PPP client configuration. Through LCP, PPP also supports authentication negotiation, as well as negotiation of encryption and compression between client and server, using compression control protocols (CCPs) and encryption control protocols (ECPs).
What is a RAS modem?
Both Windows NT and Windows 2000 include technology to allow users to dial up a server and connect to not only that server, but also to that server’s host network. This technology is known as RAS. RAS is used in smaller networks where a dedicated dial-up router is not practical or possible. In a RAS setup, you can basically connect a modem to a Windows NT or Windows 2000 server and, by way of the RAS, configure that modem as dial-out only, dial-up only, or a combination.
What is PPTP in a network?
PPTP is the Microsoft-created protocol based on PPP. It is used to create virtual connections across the Internet using TCP/IP and PPP so that two networks can use the Internet as their WAN link and yet retain private network security. PPTP is both simple and secure.

How does VPN work?
Point-to-point tunneling protocol (PPTP) and its successor layer 2 tunneling protocol (L2TP) both can help support the transmission of data in VPNs, but don’t provide any meaningful protection for this data. To this end, they can be encapsulated by IPsec, providing encryption for the traffic passing through it.
Can you log off of a network before booting?
On the flip side, there are also hardware options such as air cards or baked-in connections on certain types of embedded devices that can create a secure connection before the operating system has finished booting. In this way, the user is never off of the network; they are logging in directly every time.
What is remote access technology?
A common remote access technology in use today is the IPsec VPN. A piece of software called a VPN client is installed on the end user’s computer and is configured with details about the target network, such as the gateway IP address and a pre-shared security key. Each time the user wants to connect to the corporate network, they start the VPN client, which creates a secure connection to the corporate firewall.

Remote access connection allows users to access a network or computer remotely via an internet connection or telecommunications. This post is dedicated to secure remote access.
What is remote desktop connection?
Remote Desktop Connection (RDC) is a Microsoft technology that allows a local computer to connect to and control a remote PC over a network or the Internet. The host computer can see and interact with the target computer through the target computer’s actual desktop interface—allowing the host user to see exactly what the target user sees. It is done through a Remote Desktop Service (RDS) or a terminal service. Microsoft Windows, Linux, and MacOS have the software available that allows for remote desktop access.
What is remote assistant?
The remote assistant can be considered a subset of the remote desktop. When you connect to another computer using the remote desktop, the current user of that computer is forced to sign-out. In other words, if an employee asks you for help with a problem and you use a remote desktop to connect to his computer, it is not possible for both of you to be able to view the desktop at the same time and do the necessary work. In terms of technical support, this is a huge problem. To solve this problem, remote assistant technology was introduced. In remote assistant, technical support person and an employee with a problem are able to connect to a computer at the same time.
