Remote Desktop Protocol (RDP) is ubiquitous in enterprise environments — and it's one of the most exploited attack vectors in cybersecurity. Exposed RDP ports are scanned and probed millions of times per day by automated tools looking for weak credentials and unpatched vulnerabilities.

Why RDP Is Such a High-Value Target

RDP provides direct graphical access to remote systems — making it incredibly valuable for legitimate administrators and attackers alike. Once an attacker gains RDP access with valid credentials, they effectively have the same level of control as a local administrator sitting at the machine.

Common RDP Attack Techniques

• Brute force — Automated tools test millions of credential combinations against exposed RDP ports.
• BlueKeep and related CVEs — Unpatched RDP vulnerabilities allow unauthenticated remote code execution.
• Pass-the-hash — Stolen credential hashes are used to authenticate without the plaintext password.
• Lateral movement — Attackers use RDP to move between systems once inside the network.

Hardening Your RDP Configuration

If RDP is necessary, it must be hardened aggressively. Require Network Level Authentication (NLA), enforce MFA, restrict access to specific IP ranges, change the default port, and monitor all sessions with a PAM solution. Better yet, consider replacing direct RDP with a secure remote access gateway that provides all the functionality without the attack surface.

RDP doesn't have to be a liability. With the right controls in place — or better yet, replaced by a modern secure access solution — organizations can enable the remote connectivity their teams need without exposing themselves to unnecessary risk.
