Which statement is true regarding zones in a security context?

In a security context, the correct understanding of zones is that they share common security requirements. This concept is integral to effective cybersecurity architecture, especially in industrial environments. Different areas or zones within a network can have distinct security needs based on the nature of the assets they contain and the risks they face.

By categorizing resources into zones with similar security requirements, organizations can tailor their security policies and controls accordingly. This ensures that specific security measures—such as access controls, monitoring, and incident response protocols—are consistently applied, reflecting the unique vulnerabilities and threats present in each zone.

In contrast, the other options do not adequately capture the essence of security zones. For example, zones definitely require security policies to define the protections in place; they are not merely physical demarcations but conceptual frameworks. Ignoring zones for network management would undermine the structured approach to safeguarding the IT and OT environments within organizations. Hence, recognizing and utilizing zones based on their shared security requirements is essential for a robust security posture.
