Instance with administrative service: Remote Desktop (TCP:3389) is exposed to a wide network scope
Services and databases store data that may be sensitive, protected by law, subject to regulatory requirements or compliance standards. It is highly recommended that access to data will be restricted to encrypted protocols. This rule detects network settings that may expose data via unencrypted protocol over the public internet or to a too wide local scope.
Risk Level: Medium
Cloud Entity: Amazon EC2 Instance
CloudGuard Rule ID: D9.AWS.NET.AG2.5.Instance.3389.TCP
Covered by Spectral: No
Category: Compute
GSL LOGIC
Instance where inboundRules contain [port <= 3389 and portTo >= 3389 and protocol in ('TCP','ALL')] should not have inboundRules contain [port <= 3389 and portTo >= 3389 and protocol in ('TCP','ALL') and scope numberOfHosts() > 256]
REMEDIATION
It is recommended to remove the rules that allow permissive SSH/Remote/Admin access.
As a further protection, use CloudGuard Dynamic Access Leasing to limit access to SSH/Remote Desktop only from allowed sources and only when needed.
