Description

Introduction

As NaaS (Network as a Service) adoption grows, traditional perimeter-based security models are no longer sufficient to protect dynamic, distributed network environments. Zero Trust Network Access (ZTNA) provides a modern security framework that ensures users and devices are continuously authenticated, authorized, and monitored before granting access to network resources.

This training equips participants with the skills to design, implement, and manage ZTNA within NaaS architectures. Participants will learn about identity-centric security, micro-segmentation, secure access policies, integration with cloud and multi-tenant environments, and continuous monitoring to mitigate risk. The course also explores real-world deployment strategies, automation, and emerging trends in Zero Trust adoption for scalable and secure NaaS solutions.

Prerequisites

• Basic networking knowledge (TCP/IP, routing, switching, LAN/WAN)

• Familiarity with NaaS, SDN, and network virtualization

• Understanding of cloud computing concepts (IaaS, PaaS, SaaS)

• Basic knowledge of cybersecurity principles (authentication, encryption, firewalls)

• Awareness of access control models and compliance standards
