Network security zoning allows an organization to create and maintain a secure network environment and infrastructure by selecting proper security levels for each zone. This technique will aid in controlling and monitoring igress and egress traffic.
Common implemented zones include:
Internet Zone
This is an uncontrolled zone because it is outside the boundary of the organization.
Internet DMZ
This is a controlled zone that provides a buffer between internal networks and the Internet.
Production Network Zone
This controlled zone is a restricted zone as it strictly controls direct access from uncontrolled zones.
Intranet Zone
This is a controlled zone that usually does not have heavy restrictions.
Management Network Zone
This is a critical secured zone with strict policies and controls.
