name: Unrestricted RDP Access in Azure NSGs
author: princechaddha
severity: high
description: |
Ensure that Microsoft Azure network security groups (NSGs) do not allow unrestricted access on TCP port 3389, used for Remote Desktop Protocol (RDP), to prevent unauthorized remote access.
impact: |
Unrestricted RDP access can lead to unauthorized access and control over virtual machines, potentially resulting in data theft or malicious activities.
remediation: |
Configure NSG rules to restrict RDP access to only trusted IP addresses. Consider using VPNs or other secure methods for remote access.
