Network Security & Firewalls in Practice

Description

In an era where cyber threats evolve every day, the ability to secure your network infrastructure and implement effective firewall policies is critical for any organization. This comprehensive online training, “Network Security & Firewalls in Practice,” is designed to transform you from a beginner into a confident professional capable of defending networks using practical, industry-aligned strategies and tools.

What This Course Covers

The course begins by establishing a solid foundation in networking essentials, including TCP/IP protocols, subnetting, routing, DNS, and OSI layers, ensuring you can confidently navigate network topologies and communication flows. You will then delve into the threat landscape, learning to identify and analyze common and advanced attack vectors such as phishing, malware, sniffing, spoofing, DDoS attacks, DNS poisoning, and insider threats.

Moving forward, the training will guide you through the architecture and operational principles of firewalls, exploring different types including packet-filtering, stateful, application-layer, and next-generation firewalls (NGFW). You will learn how to design, configure, and manage firewall policies, aligning them with organizational needs while maintaining strong security postures and operational efficiency.

The course also covers Intrusion Detection and Prevention Systems (IDS/IPS), teaching you how to deploy and monitor these systems to detect and respond to threats in real-time. You will practice packet capture and analysis using tools like Wireshark, giving you the skills to identify suspicious activities, interpret logs, and perform basic network forensics.

VPN implementation and management are critical for securing remote connections, and this course equips you with the knowledge to configure secure VPN tunnels, enforce strong authentication, and mitigate VPN-related risks.

As organizations increasingly adopt cloud and hybrid environments, you will explore cloud-specific network security challenges and the use of firewalls and access controls in these infrastructures. The course also addresses wireless security, focusing on WPA3, 802.1X, and securing IoT devices in a network environment.

To solidify your knowledge, hands-on lab exercises and real-world case studies are integrated throughout the program. These practical sessions simulate network environments and attack scenarios, allowing you to implement firewall policies, analyze traffic, configure VPNs, and detect intrusions, building the confidence to apply these skills in your organization.
