Vulnerability discussion

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.

Check content

Verify firewall exceptions to inbound connections on domain workstations include only authorized remote management hosts. If allowed inbound exceptions are not limited to authorized remote management hosts, this is a finding. Review inbound firewall exceptions. Computer Configuration >> Windows Settings >> Security Settings >> Windows Firewall with Advanced Security >> Windows Firewall with Advanced Security >> Inbound Rules (this link will be in the right pane) For any inbound rules that allow connections view the Scope for Remote IP address. This may be defined as an IP address, subnet, or range. The rule must apply to all firewall profiles. If a third-party firewall is used, ensure comparable settings are in place.

Fix text

Configure only inbound connection exceptions for authorized remote management hosts. Computer Configuration >> Windows Settings >> Security Settings >> Windows Firewall with Advanced Security >> Windows 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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
