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.

iMaster NCE (Huawei’s Network Cloud Engine)is anintent-driven network management and control systemdesigned forSDN networks.

It supports both traditional and SDN-capable networks:

SNMPis used to manage and controltraditional (non-SDN) devices.

NETCONF + YANGis used to manageSDN-capable devicesin a structured and automated manner.

CLI is not a preferred method in SDN environmentsas it lacks automation and scalability.
