Core Principles of Network Defence Strategies

Master network security fundamentals for enterprise systems

Securing enterprise networks requires both solid foundations and practical skills to defend against modern cyber threats. This course gives you a comprehensive overview of network architecture, access control, device security, and monitoring techniques essential for robust defence.

You’ll build the technical knowledge and hands-on experience needed to protect enterprise networks across industries—from understanding how networks are structured to implementing the security measures that keep them safe.

Network security fundamentals and architectural design

Explore the core concepts of network design including VLANs, subnetting, and layered security zones. You’ll learn how to apply threat modelling principles to protect enterprise assets and control network traffic effectively, building networks that are secure by design.

Access control, VPNs, and securing network devices

Gain practical experience implementing Access Control Lists (ACLs), configuring Virtual Private Networks (VPNs), and securing network devices. You’ll understand encryption protocols and techniques to safeguard data as it moves across public and private networks.

Centralised authentication, monitoring, and wireless security

Learn to deploy centralised authentication using TACACS+ to manage administrative access and monitor network activity effectively. You’ll explore wireless security challenges and operations, culminating in a practical project that brings together everything you’ve learned.

You’ll walk away with confidence in your ability to secure enterprise networks in sectors like finance, healthcare, and government.

This course is ideal for network engineers, cybersecurity specialists, IT professionals, and anyone pursuing advanced skills in securing enterprise networks, particularly in sectors like finance, healthcare, and government.
