Allowing inbound access to domain workstations from other systems may allow lateral movement across systems if credentials are compromised. Limiting inbound connections only from authorized remote management systems will help limit this exposure. NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Configure firewall exceptions to inbound connections on domain workstations to include only authorized remote management hosts. Configure only inbound connection exceptions for authorized remote management hosts. Computer Configuration >> Windows Settings >> Security Settings >> Windows Defender Firewall with Advanced Security >> Windows Defender Firewall with Advanced Security >> Inbound Rules (this link will be in the right pane) For any inbound rules that allow connections, configure the Scope for Remote IP address to those of authorized remote management hosts. This may be defined as an IP address, subnet or range. Apply the rule to all firewall profiles. If a third-party firewall is used, configure inbound exceptions to only include authorized remote management hosts.
