Network Security & Firewalls in Practice

About Course

This course focuses on core network security principles and practical firewall implementation. You’ll explore how to protect network infrastructures, how attackers operate, and how to design and enforce robust defenses—emphasizing real-world application and hands-on practice

Understand core network security concepts, including the CIA triad, threat types, and attack vectors.
Differentiate and configure various firewall types such as packet-filtering, stateful, proxy, and next-generation firewalls.
Design and implement firewall policies and rules to protect enterprise networks effectively.
Set up and manage VPNs, including IPSec and SSL/TLS, for secure remote access.
Perform practical firewall configurations using pfSense and similar tools.
Analyze firewall logs and monitor network activity to detect and respond to threats.
Integrate firewalls with IDS/IPS systems and other security tools for layered defense.
Troubleshoot network security issues and optimize firewall performance.
Implement advanced firewall concepts, including application-layer filtering, geo-blocking, and high availability.
Develop incident response strategies and conduct post-incident reviews for continuous improvement.

Course Content

Module 1: Introduction to Network Security
Importance of network security in modern enterprises Overview of the CIA Triad (Confidentiality, Integrity, Availability) Common network attacks: DoS, spoofing, phishing, malware Understanding TCP/IP, subnets, and network topologies

Module 2: Fundamentals of Firewalls
What are firewalls and why are they essential? Types of firewalls: Packet-filtering firewalls Stateful inspection firewalls Proxy firewalls Next-generation firewalls Host-based and cloud-based firewalls Firewall placement and network architecture

Module 3: Firewall Policies and Rule Management
Designing effective firewall policies Creating and managing firewall rules Understanding rule order and optimization Best practices for policy enforcement Troubleshooting rule conflicts and issues

Module 4: VPN Technologies and Implementation
VPN fundamentals: why and when to use VPNs Types of VPNs: IPSec VPN SSL/TLS VPN L2TP VPN Tunnel vs. transport mode Configuring VPN tunnels for secure remote access Managing VPN users and encryption settings

Module 5: Practical Firewall Configuration (Hands-On Labs)
Installing and configuring pfSense firewall Creating firewall rules and NAT policies Configuring IPS/IDS on firewalls Monitoring logs and interpreting firewall alerts Simulated attack and defense scenarios for practice

Module 6: Network Security Monitoring & Incident Response
Monitoring firewall logs and identifying suspicious activity Integrating firewalls with IDS/IPS systems Using tools like Wireshark for packet analysis Incident response planning and reporting Post-incident analysis and continuous improvement

Module 7: Advanced Firewall Concepts
Advanced rule configuration (application-layer filtering, geo-blocking) Configuring high availability and failover Load balancing with firewalls Firewall hardening and updates

Module 8: Capstone Project & Assessment
Real-world scenario: Designing a secure network with firewall implementation Configuring a VPN for remote teams Documenting firewall policies and rule justifications Security audit and improvement plan presentation
