Huawei firewalls come preconfigured with several default security zones, each serving a specific purpose:

DMZ (Demilitarized Zone):A buffer zone between the internal network and external networks, often used to host public-facing servers like web servers.

Local:Represents the firewall itself. Traffic destined for the firewall (e.g., management traffic) is associated with this zone.

Untrust:Represents external, untrusted networks such as the Internet. Security policies typically restrict traffic from this zone.

Trust:Represents internal, trusted networks. Traffic within this zone is generally considered safe.

These zones form the foundation of firewall security policies, allowing administrators to control traffic flows between different parts of the network.
