Qué comprueba
The Windows Defender Firewall provides host-based network protection that blocks unauthorized inbound and outbound connections. Without a centrally managed firewall policy through Intune, individual devices may have inconsistent or disabled firewall settings, leaving them vulnerable to network-based attacks. Centralized firewall management ensures consistent protection across all managed endpoints regardless of network location.
Valor recomendado
Windows Defender Firewall enabled for all profiles (Domain, Private, Public); block inbound connections by default; log dropped packets
Remediación
Deploy an Intune endpoint security firewall policy that enables Windows Defender Firewall for Domain, Private, and Public network profiles with inbound connections blocked by default. Configure firewall rules for any required application exceptions and enable logging for dropped and successful connections. Monitor the firewall policy deployment status and investigate any devices reporting policy application errors or firewall disabled states.
