Mastering Network Defense Strategies

Secure your network infrastructure with VLANs, VPNs, ACLs, and wireless defense strategies from design to operations.

What you'll learn
- Apply secure design using threat modeling, VLANs, subnetting, and layered zones to control traffic and reduce enterprise risk.
- Implement ACLs and VPNs to regulate traffic by IP, protocol, port, and encrypt data across public/private networks.
- Configure AAA with TACACS+ to manage admin access and monitor network activity for threat detection and response.
- Apply advanced techniques to design and validate a secured enterprise network using integrated prior skills.

Requirements
- To fully benefit from this course, learners should have a foundational grasp of networking concepts, including how data moves through a network and how routing and switching function. Familiarity with IP addressing, subnetting, and basic routing/switching protocols will help participants engage more effectively with the practical labs and configuration exercises presented throughout the program.

Description
Network Defense Strategies empowers cybersecurity professionals to design, implement, and manage secure network infrastructures that are resilient to evolving threats. This course delves into critical concepts of network security, teaching you to build and maintain networks that can withstand attacks while ensuring continuous protection. In this specialization, you’ll explore real-world techniques like VLAN configuration for network segmentation, secure remote access via VPN tunnelling, and proactive defense mechanisms using firewalls, IDS/IPS, and SIEM systems. These best practices are grounded in industry standards and transform theoretical knowledge into practical application, helping you construct scalable, secure network environments.

Through a step-by-step approach, you will learn how to design robust network architectures and implement layered security principles, including zero trust and defense in depth, to mitigate risk and protect sensitive data. The course guides you through the entire network lifecycle—from initial design to deployment, real-time monitoring, and ongoing defense ensuring you understand how to build networks that are resilient against advanced cyber threats. You will also gain hands-on experience with traffic analysis, threat mitigation, and configuring security protocols, preparing you to handle complex network environments with confidence.

Interactive labs and guided exercises will immerse you in real-world network defense scenarios, strengthening both your technical skills and strategic thinking. Each module combines expert-led instruction with practical exercises, ensuring you not only learn the theory but also build actionable, real-world defense strategies.

Whether you're an aspiring network security professional, an IT manager, or part of a security operations team, this specialization equips you with the knowledge, tools, and techniques to defend your network infrastructure against a wide range of cyber threats.

Who this course is for:
- This course is tailored for network engineers, administrators, and cybersecurity professionals who play a key role in safeguarding organizational infrastructure. It is equally valuable for IT practitioners seeking to enhance their understanding of network defense mechanisms, as well as learners preparing for careers in network or systems security. The course bridges theoretical concepts with hands-on implementation, ensuring participants can design and operate secure networks in real-world environments.
