Check Content

The steps in this check will vary based on the host-based firewall being used in the environment. 

For Windows Firewall, type wf.msc. 

Verify that the firewall is set to On. 

Click on Inbound rules and verify that there are no any-any allow rules in any profile. 

If McAfee is installed, it will be visible in the system tray. Verify with a McAfee administrator that there are no any-any rules allowing full access. 

If no host-based firewall is installed, or a host-based firewall is configured to allow all traffic inbound, this is a finding.
