Discussion

Firewalls protect computers from network attacks by blocking or limiting access to open network ports. Application firewalls limit which applications are allowed to communicate over the network.

Check Content

Verify the operating system enabled an application firewall, if available. If it does not, this is a finding. If the operating system does not support an application firewall, this may be downgraded to a CAT III finding.

Fix Text

Ensure the operating system's application firewall is enabled, if available.
