The network slicing concept provides mobile network capability to reuse existing resources for different vertical customer requirements. The resources shared across network slices require attaching security mechanisms to isolate each data slice. The network conditions are dynamic, and data protection of data slices needs to be evaluated throughput.
The author of this research work aims to deliver a security model in the context of optimising resources for network slicing. The multi-layer network describes the architecture of mobile networks well. The service or customer demand isolates resources at one layer that shares the lower layers. Evaluating resource security protection is critical, especially security mechanisms at shared layers of resources. The author, during research, introduced an isolation scoring model for mitigating vulnerabilities or resources under attack, show dependencies between layers and requirements for protection mechanisms for lower layers. Each layer's isolation score/metric calculation is based on different criteria. Evaluate the isolation level and isolation risk at each management layer (accept, modify for self-healing purposes) and report the isolation score/metric to management in the higher layer.
The presented isolation is scored in conjunction with hierarchical management for classification resource protection based on security metrics and human behaviour. It allows for evaluating resources regarding security for the demands placed on them.
