The Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software to this effect, while the other computer must run RDP server software.
Clients for RDP are available for:
- Windows OS: Built-in with the operating system.
- macOS: Available for download from the Mac App Store.
- Linux: Clients such as rdesktop and FreeRDP.
- iOS and Android: Apps available in respective app stores.
RDP is primarily used for:
- Remote administration: Allowing IT professionals to manage servers and desktops remotely.
- Virtual meetings: Facilitating presentations and collaborative tasks.
- Technical support: Enabling technicians to diagnose and fix issues remotely.
- Accessing virtual workstations: Providing users the flexibility to work from any location.
RDP server software is supported on:
- Windows Professional and Server editions: Integrated RDP services by default.
- Linux: Using XRDP or x11rdp, among other alternatives.
Best security practices for RDP include:
- Enabling Network Level Authentication (NLA): Adds an extra layer of authentication before establishing a session.
- Using strong passwords: Reduces chances of unauthorized access.
- Keeping software updated: Ensures the latest security patches are applied.
- Limiting users who can log in: Restricts access to authorized personnel only.
- Implementing Two-factor authentication: Provides enhanced security.
- Using RDP gateways: Adds another layer of security for RDP sessions over the internet.
Best use cases for RDP are situations where direct physical access to a machine is not possible or practical. This includes telecommuting, managing data centers, and providing support to end-users remotely.
