Secure RDP: Best Practices for Remote Access

Why RDP gets attacked

RDP is one of the most targeted remote access protocols because exposed endpoints are easy to scan and brute-force. A secure deployment requires layered controls, not one single setting.

1) Never expose RDP directly to the internet

• Put RDP behind VPN, ZTNA, or a remote access gateway

• Restrict inbound access by source IP where possible

• Remove all unnecessary public NAT rules for port 3389

2) Enforce strong identity controls

• Require MFA for remote sessions

• Use conditional access and device posture checks

• Disable local admin sign-in for normal user accounts

3) Harden hosts and sessions

• Keep OS and endpoint software fully patched

• Disable clipboard/drive redirection where not needed

• Apply account lockout thresholds and idle timeouts

4) Log and monitor everything

• Track failed and successful logons

• Alert on unusual geolocation or sign-in times

• Forward logs to centralized monitoring for review

5) Test recovery and incident playbooks

Run tabletop drills for account compromise, ransomware containment, and service restoration so your team can act quickly under pressure.
