Seminar “Leveraging Software Defined Perimeter (SDP) as an Effective Implementation Approach of Zero-Trust Architecture in Enhancing Security in the SDN-Enabled Modern Campus Network Infrastructure”
11 May at 15:00 MSK
Network softwarization presents a breakthrough in designing modern networks and providing a myriad of new network services and operations. Software-Defined Network (SDN) and Network Function Virtualization (NFV) exemplars play an essential role in this transformation. SDN, NFV, and integrated SDN/NFV frameworks gain significant momentum in the sense of network security, depicting key enablers towards the on-demand protection mechanisms provisioning.
However, SDN, NFV, and SDN/NFV frameworks’ inherent security flaws pose the main challenge in adopting Network softwarization security mechanisms. To address this issue, we propose a Zero-Trust Architecture (ZTA)-Software-Defined Perimeter (SDP)-powered approach to enhance security holistically in the SDN/NFV-enabled campus network. We also provide a threat model and analyze the security and performance of the proposed model. Furthermore, we highlight possible network security function implementations in a zero-trust compliant manner to improve protection for network resources, endpoints devices, and network flows for effective threat detection and response capabilities while incurring little overhead and latency.
