ISC2 CISSP Practice Question

Network slicing is a key architectural feature introduced in 5G networks that was not present in previous cellular generations like 4G. This technology allows network operators to create multiple virtual networks on a shared physical infrastructure, each designed for specific use cases or customers. Each network slice can have different performance characteristics and security requirements.

From a security perspective, network slicing introduces new challenges for BYOD policies because corporate data may travel through different network slices with varying security levels. Organizations need to establish policies that account for how corporate data is isolated and protected across these slices, potentially implementing additional encryption or security controls for data traversing public 5G infrastructure.

While improved bandwidth, lower latency, and edge computing integration are all features of 5G networks, they represent improvements over 4G rather than fundamentally new security considerations. Network slicing represents a new architectural approach that specifically requires security policy adjustments.
