What is RDP?




RDP is a protocol that provides a graphical interface for users to interact with remote computers over a network connection. RDP uses the Remote Desktop Services (RDS) role on Windows Server 2012 or the Remote Desktop feature on Windows-based computers to enable remote access. With RDP, you can:


  • View and control the desktop of a remote computer



  • Run applications on a remote computer



  • Transfer files and clipboard data between local and remote computers



  • Print documents from a remote computer to a local printer



  • Use multiple monitors, audio, video, and other devices with a remote computer



Why use RDP?




RDP can provide many benefits and scenarios for using remote desktops, such as:


  • Administration: You can use RDP to manage and maintain your servers and computers from anywhere, without having to physically access them. You can also use RDP to perform tasks that require higher privileges or different user accounts.



  • Remote work: You can use RDP to access your work computer or applications from home or another location, without compromising security or performance. You can also use RDP to collaborate with your colleagues or clients on projects or presentations.



  • Application delivery: You can use RDP to deliver applications to your users or customers without installing them on their devices. You can also use RDP to provide access to legacy or specialized applications that are not compatible with newer operating systems or devices.



  • Virtualization: You can use RDP to create and access virtual desktops or virtual machines that run on a server or in the cloud. You can also use RDP to scale up or down your resources according to your needs and budget.



Best practices




To use RDP effectively and securely, you need to configure some settings on both the remote computer (the server or host) and the local computer (the client). You also need to follow some guidelines on how to use RDP efficiently.


How to configure RDP settings




To enable and customize RDP on Windows Server 2012, you need to install the Remote Desktop Services role and its components. To enable and customize RDP on Windows-based computers, you need to enable the Remote Desktop feature and its options. Here are some steps you can follow:



  • On the server or host computer, open Server Manager or Control Panel.



  • Select Add Roles and Features or System and Security.



  • Select Remote Desktop Services or System.



  • Select Add Roles Services or Remote Settings.



  • Select the role services you want to install for RDP, such as Remote Desktop Session Host, Remote Desktop Connection Broker, Remote Desktop Web Access, etc. or Allow remote connections to this computer.



  • Follow the instructions on the screen to complete the installation or configuration.



  • On the client computer, open Remote Desktop Connection or a web browser.



  • Enter the name or IP address of the server or host computer you want to connect to.



  • Select the options you want to use for your RDP session, such as display, local resources, experience, etc.

How to secure RDP connections




RDP connections can be vulnerable to attacks if they are not protected properly. Hackers can use various methods to intercept, modify, or steal your RDP data, such as brute force, man-in-the-middle, denial-of-service, ransomware, etc. To secure your RDP connections, you need to use encryption, authentication, firewall, and other methods. Here are some tips you can follow:



  • Use encryption: Encryption is a process that converts your data into an unreadable form that can only be decrypted by authorized parties. Encryption can prevent hackers from eavesdropping or tampering with your RDP data. You can use Transport Layer Security (TLS) or Network Level Authentication (NLA) to encrypt your RDP connections. TLS uses certificates to verify the identity of the server and the client and to establish a secure channel for data transmission. NLA uses credentials to authenticate the user before establishing an RDP session. You can enable TLS or NLA on both the server and the client side by using Server Manager, Control Panel, Group Policy, or PowerShell. For more information, see [How to enable TLS for Remote Desktop Services] or [How to enable NLA for Remote Desktop Services].



  • Use authentication: Authentication is a process that verifies the identity of the user or the device that tries to access a resource. Authentication can prevent hackers from impersonating you or accessing your resources without your permission. You can use various methods to authenticate your RDP users or devices, such as passwords, smart cards, biometrics, multifactor authentication (MFA), etc. You can configure authentication settings on both the server and the client side by using Server Manager, Control Panel, Group Policy, or PowerShell. For more information, see [How to configure authentication for Remote Desktop Services].



  • Use firewall: Firewall is a software or hardware device that monitors and controls the network traffic between your computer and the internet or other networks. Firewall can prevent hackers from accessing your computer or launching attacks on your RDP connections. You can use Windows Firewall or a third-party firewall to block or allow RDP traffic on specific ports, protocols, IP addresses, etc. You can configure firewall settings on both the server and the client side by using Server Manager, Control Panel, Group Policy, or PowerShell. For more information, see [How to configure firewall for Remote Desktop Services].



  • Use other methods: Besides encryption, authentication, and firewall, you can also use other methods to secure your RDP connections, such as:



  • Use strong passwords: Passwords are one of the most common ways to authenticate your RDP users. However, passwords can also be easily guessed or cracked by hackers if they are weak or reused. You should use strong passwords that are long, complex, unique, and changed regularly. You should also avoid writing down or sharing your passwords with anyone.



  • Use VPN: VPN (Virtual Private Network) is a technology that creates a secure tunnel between your computer and a remote network over the internet. VPN can encrypt and protect your RDP traffic from being intercepted or modified by hackers. You can use Windows VPN or a third-party VPN service to connect to your server or host computer before launching an RDP session.



  • Use antivirus: Antivirus is a software that detects and removes malicious software (malware) from your computer. Malware can infect your computer and compromise your RDP security by stealing your credentials, spying on your activities, or disrupting your connections. You should use a reputable antivirus software and keep it updated regularly. You should also scan your computer for malware before and after using RDP.



  • Use patches: Patches are updates that fix bugs or vulnerabilities in your software or operating system. Patches can improve your RDP security by preventing hackers from exploiting known flaws or weaknesses in your system. You should use Windows Update or a third-party patch management tool to install the latest patches for your server, host, and client computers. You should also check for new patches frequently and apply them as soon as possible.



How to use RDP efficiently
