Remote Desktop Protocol (RDP)

RDP or Remote Desktop Protocol is a technical standard that enables remote use of a desktop computer. In other words, RDP allows you to connect to a remote desktop computer from a separate computer. As a result, it's easy to access the files on a remote desktop computer and make edits to them.

Virtual Network Computing (VNC) and ICA are used as remote desktop software, but they have not been as popular as RDP. The ease of use of RDP has made it easier for remote users to connect to their work computers.

RDP is a network protocol developed by Microsoft and works smoothly on Windows operating systems. After RDP was launched, it was also made available for use on operating systems such as Mac, Linux and Unix.

 

How Does RDP Work?

The user's required actions, clicks, and writings are transmitted to the connected desktop computer via the internet. Essentially, the user easily uses the computer they connected to the remote desktop as if it were in front of them.

There are two components for RDP connections to work. These are the RDP server and RDP client. The RDP client allows you to control the RDP server. In doing so, it provides remote access via a special network between the two computers.

All requests, writings, and clicks that the user wants to make are sent to this special network via the transmission protocol called TCP/IP. Thus, the user's request is safely fulfilled because RDP encrypts and transmits all data.

RDP divides the connection into nine stages. The stages of RDP connection are: sending a connection request, agreement, channel connection, security applications, configuration in security settings, licensing, adding requests, ending the connection and data exchange.

 

What are the Advantages of RDP?

RDP has many advantages. So, what exactly are advantages of RDP?

  1. RDP does not require a VPN.

  2. It securely stores all data on the user's desktop.

  3. RDP allows users to work from anywhere they want. It's pretty simple to reach remote desktop and the files in it using RDP.

  4. RDP simplifies the jobs of experts providing technical support and system maintenance when there's a problem with the computer.

 

Features of RDP

The features of RDP primarily include the following:

  • It creates a secure connection between desktop computers.
  • It allows to work on different operating systems.
  • It supports identity verification.
  • It decreases bandwidth.
  • It supports GPU also know as Graphics Processing Unit.
  • The files on the remote desktop can be edited and even printed.

 

What are the Disadvantages of RDP?

  1. RDP may not work with full performance where the connection speed is slow. Delays can occur in user requests. These delays can lead to a decrease in productivity.
  2. Furthermore, RDP has some security vulnerabilities. The remote desktop may be vulnerable to malicious attacks.

 

What are the Security Vulnerabilities of RDP?

Any hardware or software error that allows attackers to gain unauthorized access is called a security vulnerability. RDP also has some security vulnerabilities. The most important RDP security vulnerabilities are:

  1. Weak session login information. There are passwords created by users on desktop computers. These passwords protect the privacy and security of documents in the computer. However, if the same passwords are used when logging in remotely with RDP, this can turn into a security threat. Companies sometimes skip these measures, do not manage the passwords and leave the desktop computer open to threats.
  2. RDP connections occur on the 3389* connection port. Malicious attackers may realize that this is the connection port and target this connection.
  3. Another RDP security vulnerability is called BlueKeep, which allows remote code execution. BlueKeep allows attackers to send a request to the connection port, which results in any code being executed remotely on the computer.

 

How to Fix RDP Security Vulnerabilities?

  1. The latest version of the RDP protocol can be used to eliminate these security vulnerabilities.
  2. For weak login information, users can change their desktop computer's password to be a stronger password. Additionally, procedures like two-factor authentication can be added as a solution to this issue.
  3. Firewall rules can be introduced against attack on the connection port. The company can manually accept traffic from employees' IP addresses and can block all passage of connection port traffic other than this. However, determining the IP address of all devices and transferring this to the system requires much manual effort.

 

Development of RDP

The poor quality of RDP's graphic interface was one of its biggest problems. RDP updates developed over the years as follows:

  • In 2008, Microsoft launched RemoteFX as an advanced version of RDP.
  • In 2012, RemoteFX was improved. This version used adaptive graphics.
  • In 2016, with the addition of applications of graphics processing unit (GPU) for OpenCL/OpenGL and PCIe transition, the popularity of RDP was increased.

 

How to Enable Remote Desktop on Windows?

The remote desktop activation feature is not available in every version of Windows. Windows devices that have the remote desktop option only allow a single RDP connection. If multiple user connections are required, it is necessary to set up the RDS system. Nevertheless, creating a remote desktop connection on Windows is quite easy.

 

  1. Click the Start button.
  2. Go to Settings > System Settings. From here you can enable the Remote Desktop Connection option.
  3. If you want only certain users to be able to connect to the RDP server, you can enable Network Level Authentication (NLA) in the Advanced Settings option.

 

What are the Best RDP Alternatives?

You can form more secure connections by using alternative remote desktop software.

 

1. SolarWinds Dameware

SolarWinds Dameware contains tools that can be used by both in-house and support teams. SolarWinds is cloud-based. Its benefits include multi-factor authentication, support for multiple platforms, and a help desk that users can always reach. There's also a 14-day free trial period.

 

2. RemotePC

It provides encrypted remote desktop access and supports almost all operating systems. The user-friendly interface supports drag and drop functionality.

 

3. TeamViewer

It's a remote desktop tool that supports almost every operating system. Its easy and understandable use attracts users. It also supports communication methods such as text, video and audio.

 

4. Chrome Remote Desktop

This is a quick and free remote desktop support that can be used in the Google Chrome browser. The greatest advantages are that it is completely free and the installation is extremely simple.
