Network security groups provide filtering of ingress and egress network traffic to OCI resources at the VNIC level. It is recommended that no network security group allows unrestricted ingress access to TCP port 3389 from 0.0.0.0/0 (IPv4) or ::/0 (IPv6). Removing unrestricted connectivity to remote console services, such as Remote Desktop Protocol (RDP), reduces a server’s exposure to risk.
Remove or modify ingress security rules that allow RDP access from 0.0.0.0/0 (IPv4) or ::/0 (IPv6). Instead, restrict RDP access to specific IP ranges or use VPN connections. For guidance on configuring network security groups, refer to the Network Security Groups section of the Oracle Cloud Infrastructure documentation.
