This module introduces foundational concepts in network security, including the CIA triad, common threats and threat actors, vulnerabilities (both technical and human), and essential security mechanisms such as authentication and password management. Learners will explore how attackers exploit weaknesses and how to mitigate these risks to protect organizational data and systems.

This module guides learners through securing device access and implementing VPN solutions using Cisco IOS routers. You will gain hands-on experience configuring authenticated access, encrypting passwords, and establishing both remote access and site-to-site VPNs to protect network resources. By the end, you'll understand best practices for device security and remote connectivity.

This module introduces the principles and practical steps for configuring Access Control Lists (ACLs) on Cisco IOS routers. Learners will explore how ACLs filter network traffic, understand the use of wildcard masks, and apply best practices for creating both standard and extended ACLs. Hands-on exercises reinforce the skills needed to implement effective network security controls.

This module explores common Layer 2 and wireless security threats, such as VLAN attacks, DHCP spoofing, and Spanning Tree attacks, and demonstrates practical methods to defend against them. Learners will gain hands-on experience implementing security features like port security, DHCP snooping, and Dynamic ARP Inspection on Cisco devices. The module also covers wireless authentication methods to enhance network protection.

This module introduces key concepts in network automation, including data formats, APIs, and configuration management. Learners will explore how modern networks leverage automation tools and intent-based networking to streamline operations and improve efficiency. Practical examples illustrate how these technologies are applied in real-world enterprise environments.
