RDP

There are two essential terminologies that you must be aware of.

  • RDP Server
  • RDP Client

What is an RDP server?

An RDP server is simply the Windows PC or a server with which you wish to establish a connection.

What is RDP Client?

An RDP client is a PC or a device with a pre-installed RDP client app that helps you to control the server.

Additionally, RDP is strictly a Windows-only protocol, so the remote connections are only built with the PCs or Windows servers that support it. For instance, Windows 10 home, can be used only as a client and not as a server. Hence, be careful while building a connection. 

Moving further, you can only build one connection with the Windows PC, whereas to create a nexus amongst several users at the same time, you have to use a Windows server with an installed and enabled RDS component. Also, there can be instances where you want to build a connection with an enterprise network. In that case, you must have an installed and configured Remote Desktop Gateway service. Usually, an internal VPN or a Virtual Private Network is needed, but this service replaces that requirement and adds additional security too.

Now that you have gained a decent understanding of the meaning of Remote Desktop Protocol (RDP), let us begin the process by understanding, how to enable the remote desktop connection and how to use RDP.

To discover the optimal remote desktop software that meets your specific requirements, dive into our comprehensive review on the best remote desktop softwares at MonoVM.

4. Personal Use

Even if you are not an IT Professional, you can use the Remote Desktop for personal use too. You can use it for troubleshooting purposes as well as extend it to support and manage each other’s devices. Moving on to the next segment, let us now understand how a remote desktop protocol works!

After learning about the advantages and ease associated with RDP, it’s time to understand the mechanism behind it.

Basically, all the commands passed by the user sitting on a different machine are transferred to the desktop computer remotely. 

The RDP protocol initiates a dedicated network channel that further sends the data between the connected machines. The network port 3389 is used to establish a connection. 

Whenever any command is sent through mouse or keyboard or any other important data for that matter, it is sent via TCP/IP. TCP/IP is the transport protocol that is used mostly for Internet traffic. Whereas, the RDP encrypts the data and provides additional security to the connections over the internet.

As you have seen, all the commands that you give must be transmitted with encryption. This may take a few milliseconds or sometimes a slight delay may occur. For instance, if you are a user, and you double click on an application, The double click may not occur as soon as you give the command. 

The reason is that sometimes it takes a few milliseconds for the action to transfer to your target desktop.

Further, RDP is not just about ease and accessibility, there are ample other benefits associated with the same. Let’s have a look!

  • Speed
  • No VPN Required
  • Flexibility
  • Savings

1. Speed

As you have seen, there is no physical intervention, so you save a lot of time. Remote Desktop helps you to solve the issues of not just others but your own device in seconds.

2. No VPN Required

When we talk about the remote desktop protocol, you do not require a VPN. It does not store the data on cloud servers, instead, it keeps the data and information secure on the device of the user. Moreover, it is highly recommended for the employees to work from home. 

3. Flexibility

You can deliver your work from sitting anywhere in the world. At your comfort, you can achieve satisfaction related to your work.

4. Savings

Remote Desktop provides you with a lot of cost reduction factors. For instance, no travel cost. It works on the basis of BYOD, i.e., Bring Your Own Device. Therefore, you do not require office essentials. It results in increased effectiveness and productivity.

Optimizing the performance of Remote Desktop Protocol (RDP) sessions is essential for ensuring a smooth and responsive remote access experience, especially in environments with bandwidth limitations or high latency. Here are practical tips and techniques for enhancing RDP performance:

Adjust Visual Effects

  • Simplify Visuals: Reduce the use of visual effects on the remote desktop. In the RDP settings, choose to display a lower color depth and disable features like desktop background, font smoothing, and window animations. This reduces the amount of graphical data that needs to be transmitted, improving performance.

  • Screen Resolution: Lower the screen resolution for the remote session. A lower resolution requires less bandwidth to transmit screen updates, leading to a more responsive experience.

Limit Resource Use

  • Close Unnecessary Applications: On the remote computer, close applications and processes that are not needed for the task at hand. This frees up system resources, improving the performance of essential applications.

  • Optimize Multitasking: Avoid running resource-intensive applications simultaneously during the RDP session. Focus on one application at a time to maximize responsiveness.

Optimize Network Settings

  • Persistent Bitmap Caching: Enable persistent bitmap caching in the RDP client settings. This feature caches frequently used images and elements on the local device, reducing the need to retransmit them and thus saving bandwidth.

  • Adjust Experience Settings: Based on your network connection, adjust the RDP experience settings (available in the RDP client). For slower connections, select options that reduce the amount of data transmitted, such as disabling themes and wallpaper.

  • Use a Wired Connection: If possible, use a wired network connection instead of Wi-Fi for both the client and the remote machine. Wired connections are generally more reliable and have lower latency compared to wireless connections.

Manage Bandwidth

  • Limit Bandwidth Usage: If the RDP session is competing with other network traffic, consider using Quality of Service (QoS) settings on your network to prioritize RDP traffic. Additionally, avoid large file transfers and streaming video during RDP sessions to conserve bandwidth.

  • Network Compression: Enable network compression for the RDP session if supported by the client and server. Compression reduces the size of the data transmitted between the client and server, improving performance over limited bandwidth connections.

Upgrade Hardware and Infrastructure

  • Server and Client Hardware: Ensure that both the RDP server and client machines have adequate hardware to support the tasks being performed. Upgrading memory, CPU, and storage can significantly impact performance.

In some cases, cybercriminals may attempt to steal user credentials to gain access to RDP-enabled systems. This emphasizes the importance of user education regarding phishing threats and the significance of using multi-factor authentication (MFA) to add an extra layer of security.

Securing Remote Desktop Protocol (RDP) sessions is crucial to protect against unauthorized access and potential cybersecurity threats. Implementing robust security measures can significantly enhance the safety of remote connections. Below are key best practices for securing RDP sessions:

Use Strong Encryption

  • Enable High-Level Encryption: Ensure RDP sessions are configured to use high-level encryption, protecting data in transit from eavesdropping or interception. This can be configured through Group Policy or directly within the RDP settings.

  • TLS/SSL Certificates: Use Transport Layer Security (TLS) or Secure Sockets Layer (SSL) certificates to authenticate RDP sessions. This adds an additional layer of security by verifying the identity of the remote computer.

Implement Network Level Authentication (NLA)

  • Require NLA: NLA requires users to authenticate before a full RDP session is established, significantly reducing the risk of brute-force attacks and other unauthorized access attempts. It ensures that RDP resources are only allocated to authenticated users.

  • Strong Password Policies: Combine NLA with strong password policies, including complexity requirements and regular password changes, to further secure access.

Configure Firewalls and Access Controls

  • Limit RDP Access Through Firewalls: Configure firewalls to restrict incoming RDP connections only from known IP addresses or subnets. This minimizes the exposure of RDP servers to potential attackers.

  • Use Port Filtering and Change Default Ports: While the default RDP port is 3389, changing it to a non-standard port can reduce the risk of automated scans and attacks. Additionally, employ port filtering to monitor and control data flow to and from RDP-enabled devices.

Additional Best Practices

  • Enable Account Lockout Policies: To combat brute-force attacks, enable account lockout policies that temporarily lock accounts after a certain number of failed login attempts.

  • Use Multi-Factor Authentication (MFA): Where possible, implement MFA to require a second form of verification beyond just a password. This significantly enhances security, especially for critical or high-value systems.

  • Keep Systems Updated: Regularly update RDP clients and servers with the latest security patches and software updates. This helps protect against vulnerabilities that could be exploited by attackers.

  • Monitor RDP Logs and Sessions: Regularly review RDP logs for unauthorized access attempts or irregular activity. Implementing session monitoring can also help detect and respond to suspicious activities in real-time.

  • Disable RDP When Not In Use: If RDP is not required for day-to-day operations, consider disabling it or restricting its use to when it is needed. This reduces the potential attack surface.
