Innovative Approaches to Network Segmentation in Cloud Native Environments for Improved Multi-Tenancy

Abstract

Network segmentation is one of the most important strategies to improve on security and performance while running cloud native architectures in multi-tenant scenarios. The research will cover the innovative approaches towards network segmentation using Software Defined Networking (SDN), Kubernetes Network Policies, and Zero Trust Network Architecture (ZTNA). Getting control of what network traffic is processed in each tunnel allows for dynamic and granular methods for controlling what traffic is allowed to flow through a tunnel while reducing the associated security risk. However, the study informs us about the benefits of micro segmentation, enforcing the policies, the identity based access controls to mitigate the cyber threats. Other challenges include scalability, policy management, interchangeability, and others. Integration of these approaches in cloud service providers helps in gaining better security, operational efficiency and compliance in the multi-tenant cloud environment.
