What are the security domains used in Zone-Based Policy Firewall called?

1. Security Policies

2. Security Layers

3. Security Zones

4. Safety Areas

The correct answer is: Security Zones

In the context of a Zone-Based Policy Firewall, the correct term for the segments that are designated to enforce traffic policies is "Security Zones." Each security zone represents a logical grouping of interfaces, and it is used to define how traffic should be treated when it moves from one zone to another. This allows for a more granular and organized approach to managing network security, as rules can be applied based on the zone-to-zone traffic rather than on specific interfaces alone. Security zones facilitate the implementation of policies that can specify whether traffic is allowed or denied between zones, contributing to an effective security architecture within the network. By using these zones, network administrators can create a clear, structured means for defining and managing access control and avoid potential security risks. The other terms provided, while relevant to security concepts, do not accurately represent the specific structural components of a Zone-Based Policy Firewall. For instance, "Security Policies" refers to the actual rules that define how traffic is handled rather than the zones themselves, "Security Layers" might imply levels of protection but lack the specificity of zones, and "Safety Areas" is not a standard term used in network security frameworks. Thus, "Security Zones" is the precise terminology used to describe these fundamental components of the firewall architecture.
