Line 91:
Zones are logical segments within a network that group together devices with similar security requirements. By partitioning a network into zones, such as "[[Operational technology|Technical]]", "[[Wide area network|WAN]]", "[[Local area network|LAN]]", "[[Wide area network|Public]]," "[[Private network|Private]]," "[[DMZ (computing)|DMZ]]", and "[[Wireless network|Wireless]]," administrators can enforce policies that control the flow of traffic between them. Each zone has its own level of trust and is governed by specific firewall rules that regulate the ingress and egress of data.
 
IA typical default is to allow all traffic from LAN to WAN, and to drop all traffic from WAN to LAN.
