Which concept describes the ongoing removal of the network perimeter and reliance on controls across the environment?

• A. Data Sovereignty
• B. BYOD
• C. Jurisdiction
• D. De-Perimeterization

Answer: (D)

De-perimeterization is the idea of removing the traditional network boundary and securing the environment with controls that apply across all locations, devices, and services. As organizations move to cloud services, mobile devices, and remote work, the idea of a single trusted edge becomes less realistic, so security relies on continuous verification and protection at every access point. This includes strong identity and access management, device health checks, encryption, micro-segmentation, and ongoing monitoring rather than depending on being inside a fixed network perimeter. Data protection and access decisions are made based on context and posture, not just network location.

Data sovereignty is about where data physically resides and which laws apply to it. BYOD refers to employees using their personal devices for work. Jurisdiction relates to legal authority and applicable laws. None of these describe the shift away from a defined network boundary to security controls that span the entire environment the way de-perimeterization does.
