Which term describes the considerations for positioning security controls to protect network zones and individual hosts to implement a defense in depth strategy and meet overall security goals?

• A. Network zoning
• B. Security policy
• C. Cable mapping
• D. Device placement

Answer: (D)

Positioning security controls across a network to create layered defenses is about device placement. In a defense-in-depth approach, you decide where to deploy each control—firewalls, intrusion detection systems, endpoint protections, access controls, and so on—and how they span network zones and individual hosts. The goal is to have multiple, complementary layers that protect assets even if one layer is breached, while aligning with security goals and performance considerations. This concept differs from network zoning (dividing the network into zones for containment), a security policy (the rules governing behavior and access), and cable mapping (the physical layout of connections). By focusing on where to place the security controls themselves, you ensure the right protections are in the right places to achieve comprehensive coverage.
