In a zone-based security model, how should access control requirements apply to hosts within the same zone?

In a zone-based security model, hosts that reside within the same zone should share the same access control requirements. This is because zones are typically designed to segment networks based on similar security needs and risk levels. By establishing uniform access control rules for all devices within a single zone, organizations can simplify management, ensure consistency in security policies, and minimize the risk of configuration errors.

Shared access control requirements within a zone take into account the similar function and risk profile of the hosts. For example, if hosts in a zone are all dedicated to a similar purpose, such as a web server farm, then they can be subject to the same security policies regarding firewall rules, intrusion detection configurations, and other security measures. This uniformity helps streamline security management and monitoring efforts, making it easier to enforce policy compliance and respond to incidents effectively.

Implementing different access control requirements for hosts within the same zone could lead to confusion and potential security gaps, as it complicates the enforcement of security policies. Moreover, requiring stricter controls in a zone designed for low-risk hosts could unnecessarily hinder functionality and performance, while isolating hosts in the same zone may negate the benefits of having them grouped together for operational efficiency. Thus, sharing access control requirements aligns with the fundamental principles of a
