How to secure Remote Desktop Protocol (RDP)?

To safely use Remote Desktop Protocol (RDP), the following measures need to be taken: 1. Use strong passwords and enable multi-factor authentication (MFA), avoid common vocabulary or birthday passwords, and combine mobile phone verification codes and other methods to enhance security; 2. Modify the default port (such as 3389) and restrict access to the source IP, the firewall only releases specific IPs, and improves scanning defense capabilities; 3. Enable network layer authentication (NLA), verify user identity before connection, and prevent man-in-the-middle attacks; 4. Regularly audit logs and close useless accounts, monitor login behavior through event viewer, and promptly detect exceptions and handle them. Implementing the above configuration can greatly improve RDP security.

Using two-factor authentication with Remote Desktop

Remote desktop requires two-factor authentication because it only relies on usernames and passwords by default, and is susceptible to brute-force cracking and password leakage, especially when exposed to public networks. With two-factor authentication (2FA), it is difficult for an attacker to bypass layer 2 verification, such as SMS verification codes, dynamic codes, or hardware tokens, even if the password is stolen. Implementation methods include: 1. Use third-party remote desktop software that supports 2FA, such as AnyDesk and TeamViewer; 2. The enterprise environment can cooperate with NPS and RADIUS servers such as DuoSecurity or Microsoft NPS extensions; 3. Azure virtual machine users can enable MFA in combination with AzureAD. Individual users recommend using the remote control with built-in 2FA function directly.
