Introduction

This course provides a comprehensive understanding of network security implementation within ArcOS, focusing on policies, access control lists (ACLs), and secure configuration practices. Participants will learn how to protect ArcOS-based environments from internal and external threats, enforce granular access policies, and ensure secure communication between network elements. The training combines theoretical concepts with hands-on exercises to help engineers strengthen their ArcOS security posture effectively.

Prerequisites

• Basic understanding of ArcOS fundamentals and CLI commands

• Knowledge of networking concepts such as IP addressing and routing

• Familiarity with security principles, firewalls, and access control

• Optional: Exposure to automation or SDN-based security management
