Suitable Scalability Management Model for Software-Defined Perimeter Based on Zero-Trust Model

The software-defined perimeter (SDP), a zero-trust model developed by the Cloud Security Alliance, has been attracting attention in technological industry since its introduction to world adapting digital transformation. Many trust models have introduced meet growing demands for cyber security, such as public key infrastructure, soft-ware-defined network, and virtual private network. SDP particularly gained importance because no one can be trusted. With of new technical devices, there is now need improve newly technology on various grounds when customers adapt devices. In this work, we discuss how overcome current issues relating scalability, reliability, usability, etc. As number organizations that share information online continues expand, scalable reliable are both easy maintain cost efficient evolving organizations. To need, proposed several enable easier installation management real networks with different organizational structures. Specifically, propose hierarchical, bridge, hybrid, mesh models. results qualitative quantitative evaluations showed bridge most suitable four an extension SDP.
