RDP

Remote Desktop Protocol delivers interactive Windows sessions over TCP/3389 and is a recurring ransomware entry point when exposed.

FoundationalUpdated 2026-09-01

Overview

RDP supports network level authentication, TLS transport and gateway brokering. Session hosts can be pooled for multi user desktop services or published per application.

Internet exposed RDP is one of the most reliably exploited services in existence. Publish it only through a gateway or Zero Trust broker, with MFA and account lockout in place.

Security considerations

  • Never expose 3389 directly; require a gateway plus phishing resistant MFA.
  • Restrict who may log on remotely and monitor for password spraying against exposed gateways.
